To solve for k in the equation 4 2/5 + k = -3 2/11, we convert the mixed numbers to improper fractions, find a common denominator, and perform algebraic operations to isolate k. The solution is k = -417/55.
The student is asking to solve the equation 4 2/5 + k = -3 2/11 for k. To solve this, you would convert the mixed numbers into improper fractions, then isolate the variable k by performing algebraic operations.
Steps to Solve for k:
Convert mixed numbers to improper fractions: 4 2/5 becomes 22/5 and -3 2/11 becomes -35/11.Write the equation with improper fractions: 22/5 + k = -35/11.Find a common denominator: In this case, the common denominator for 5 and 11 is 55.Write both fractions with the common denominator: 22/5 becomes 242/55, and -35/11 becomes -175/55.Rewrite the equation: 242/55 + k = -175/55.Subtract 242/55 from both sides to isolate k: k = -175/55 - 242/55.Combine the fractions: k = (-175 - 242) / 55.Calculate k: k = -417/55, which can be simplified if necessary.By following these steps, we can find that the value of k is -417/55. We have used algebraic operations, improper fractions, and common denominators to solve the equation.
Yunika downloaded four applications for $2.99 each to her cell phone. The remaining applications that Yunika purchased cost $1.99 each.If she downloaded x total applications, which of the following equations can be used to find how much Yunika spent on cell phone application downloads?
A. y = 1.99(x - 4) + 11.96
B. y = 11.96(x - 4) + 1.99
C. y = 1.99x + 11.96
D. y = 11.96x + 1.99
Answer:
THE ANSWER IS A and I GO TO AMANA ACADEMY CHARTER SCHOOL
Step-by-step explanation:
Yunika downloaded four applications for $2.99 each to her cell phone. So, these four applications cost a total of $11.96.
Each remaining application that Yunika downloaded cost $1.99. Since represents the total number of applications, then ( - 4) represents the number of $1.99 applications she downloaded.
Therefore, the equation that can be used to find how much Yunika spent on cell phone application downloads is shown below.
= 1.99( - 4) + 11.96
Final answer:
The equation to represent the total amount spent by Yunika on cell phone application downloads is y = 1.99(x - 4) + 11.96, which corresponds to option A.
Explanation:
To find the equation representing the total amount spent by Yunika on cell phone application downloads, we can let y represent the total amount spent and x represent the total number of applications downloaded. As given, Yunika downloaded four applications at $2.99 each which gives us a fixed cost of 4 applications × $2.99 = $11.96. The remaining applications cost $1.99 each, so for every application after the first four, Yunika spends $1.99. The total amount spent, y, can thus be calculated by multiplying the number of additional apps (which is x - 4) by their cost ($1.99), and then adding the fixed cost ($11.96).
Therefore, the equation can be written as y = 1.99(x - 4) + 11.96, which matches option A. This equation takes into account both the initial fixed cost for the first four apps and the variable cost for the remaining apps.
what are two`fractions whose product is -3/5
To find two fractions whose product is -3/5, we can choose any two fractions that follow the rules of multiplying fractions. For example, the fractions 1/5 and -3/1 or -4/5 and 3/4 both have a product of -3/5.
Explanation:To find two fractions whose product is -3/5, we need to consider the rules of multiplying fractions. When we multiply two fractions, we multiply their numerators to get the new numerator and multiply their denominators to get the new denominator. In this case, we can choose any two fractions that satisfy these rules and have a product of -3/5.
For example, let's consider the fractions 1/5 and -3/1. When we multiply these fractions, we get (1 × -3) / (5 × 1) = -3/5.
Another example is the fractions -4/5 and 3/4. When we multiply these fractions, we get (-4 × 3) / (5 × 4) = -12/20, which can be simplified to -3/5.

Select the equation in which the graph of the line has a negative slope, and the y-intercept equals 10. Answer 10x + 5y = –25 5x – 10y = –12 20x + 5y = 50 2x + 6y = 10
The correct equation that represents a line with a negative slope and a y-intercept of 10 is 20x + 5y = 50, which rearranges to y = -4x + 10 in slope-intercept form.
Explanation:The question asks us to select the equation where the graph of the line has a negative slope and a y-intercept equal to 10. To find this, we need to rearrange each equation to the slope-intercept form, which is y = mx + b, where 'm' stands for slope and 'b' stands for y-intercept.
Let's analyze each equation:
10x + 5y = –25 rearranges to y = –2x - 5, having a slope of –2 and a y-intercept of -5.5x – 10y = –12 changes to y = 0.5x + 1.2, showing a positive slope of 0.5 and a y-intercept of 1.2.20x + 5y = 50 modifies to y = –4x + 10, which has a negative slope of –4 and a y-intercept of 10. This is the correct answer.2x + 6y = 10 turns into y = –1/3x + 10/6, having a negative slope of –1/3 but a y-intercept of 10/6.Thus, the correct equation is 20x + 5y = 50, which, when written in the slope-intercept form, displays a negative slope and meets our specification of a y-intercept equal to 10.
Final answer:
The equation with a graph that has a negative slope and a y-intercept of 10 is 20x + 5y = 50, when rearranged into slope-intercept form, it shows a slope of -4 and a y-intercept of 10.
Explanation:
To find the equation in which the graph of the line has a negative slope and a y-intercept equals 10, we need to convert the given equations into slope-intercept form, which is y = mx + b, where 'm' represents the slope and 'b' represents the y-intercept.
Starting with each equation:
10x + 5y = -25 can be rearranged to 5y = -10x - 25, and then y = -2x - 5. Here, the slope (m) is -2, which is negative, but the y-intercept (b) is -5, not 10.
5x - 10y = -12 rearranged gives -10y = -5x - 12, and then y = (1/2)x + 1.2. This line has a positive slope, not a negative.
20x + 5y = 50 is rearranged to 5y = -20x + 50, and then y = -4x + 10. This line has a negative slope (-4) and the y-intercept is 10, so this is the correct equation.
Finally, 2x + 6y = 10 rearranged gives 6y = -2x + 10, and then y = -(1/3)x + (10/6), which simplifies to y = -(1/3)x + 1.6667. The slope is negative, but the y-intercept is not 10.
Therefore, the correct equation is 20x + 5y = 50, because its graph has a negative slope and y-intercept of 10.

A local hamburger shop sold a combined total of 605 hamburgers and cheeseburgers on Friday. There were 55 more cheeseburgers sold than hamburgers. How many hamburgers were sold on Friday?
The local hamburger shop sold 275 hamburgers on Friday, which was determined by setting up a system of equations to find the individual sales of hamburgers and cheeseburgers based on the given total sales and difference in numbers.
The question asks us to determine how many hamburgers were sold on a specific day, given the total number of hamburgers and cheeseburgers and the difference in their individual sales numbers. Let's denote the number of hamburgers sold as H and the number of cheeseburgers as C. We are told that the total number of burgers sold is 605, so we can write the equation H + C = 605. We also know there were 55 more cheeseburgers sold than hamburgers, giving us the equation C = H + 55. To find the number of hamburgers sold, we need to solve these two equations simultaneously.
Substituting the second equation into the first, we get:
H + (H + 55) = 6052H + 55 = 6052H = 605 - 552H = 550H = 550 / 2H = 275Therefore, the hamburger shop sold 275 hamburgers on Friday.

Francisco makes $12 per hour doing part time work on Saturdays. He spends $4 on transportation to and from work. The equation y=12x-4 gives his earnings y, after transportation costs, for working x hours. Make a table for values for this situation. Please help.
In the given linear equations, we can use the equation y=12x-4 to create a table of earnings for different numbers of hours Francisco might work, taking into account his transportation costs. For example, if he does not work he loses $4 (-$4); if he works one hour he earns $8; if he works two hours he earns $20; if he works three hours he earns $32.
Explanation:In the equation y=12x-4, 'x' represents the number of hours Francisco works, and 'y' gives his earnings after transportation costs. Let's start creating a table using different values for 'x (hours)'.
For 0 hours (x=0), we substitute x into the equation to get y = 12*0 - 4 = -$4. Since Francisco can't earn negative money, we can consider this as him simply not going to work.For 1 hour (x=1), y = 12*1 - 4 = $8.For 2 hours (x=2), y = 12*2 - 4 = $20.For 3 hours (x=3), y = 12*3 - 4 = $32.So, the table would look something like this:
(0, -$4)(1, $8)(2, $20)(3, $32)This table provides four possible combinations of hours worked (x) and the corresponding earnings (y), taking into account the cost of transportation.

Sasha lives 1,493 miles from her grandmother. One year, Sasha's family made 4 round trips to visit her grandmother. How many miles did they travel in all?
Final answer:
Sasha's family traveled a total of 11,944 miles over the course of the year by making 4 round trips to visit her grandmother, with each round trip being 2,986 miles.
Explanation:
The student is asking a mathematics question related to calculating the total distance traveled during multiple round trips. In this problem, Sasha's family traveled 1,493 miles to visit her grandmother, and they made this trip 4 times in a year. To find out how many miles they traveled in all, we need to calculate the distance of one round trip and then multiply by the number of round trips made.
A round trip consists of going to the grandmother's house and then returning back, so that's 1,493 miles each way. Therefore, one round trip would be:
1,493 miles (to grandmother) + 1,493 miles (back) = 2,986 miles.
Since they made 4 round trips, we calculate:
2,986 miles (for one round trip) x 4 (round trips) = 11,944 miles.
Thus, Sasha's family traveled a total of 11,944 miles to visit her grandmother over the course of the year.

Which ordered pair is a solution of the equation y = x – 3?
The ordered pair (5, 2) is the solution to the equation y = x - 3.
Explanation:
To find the solution to the equation y = x - 3, we need to substitute the x-value and see if the resulting y-value matches. Let's check each ordered pair:
For (-2, 5), substituting x = -2, we get y = -2 - 3 = -5, not a match.
For (-5, 2), substituting x = -5, we get y = -5 - 3 = -8, not a match.
For (2, 5), substituting x = 2, we get y = 2 - 3 = -1, not a match.
For (5, 2), substituting x = 5, we get y = 5 - 3 = 2, which is a match!

What is the distance between point A (−1, 3) and point B (−7, 3) ?
1 units
3 units
6 units
8 units
Answer:
The distance between point A and the point B is:
6 Units.
Step-by-step explanation:
The Cartesian plane is known as 2 perpendicular number lines between them, one horizontal and one vertical, which are cut at a point called the origin.
And the coordinates are given by the values of X and Y (x, y)
Where X are horizontal values and Y are vertical values.
By placing the point (−1, 3) and the point (−7, 3) we realize that two values of Y are exactly the same on the line.
But the values of X are different from each other, so the units of the distance between them are counted.
-7U - (- 1U) = -6U
But since the distance units cannot be negative then the answer is 6 units of distance.

C: 1
D: 9
The x-intercept of a line with a slope of -3 and a y-intercept of 3 is 1(C). This is calculated by setting y = 0 in the equation of the line (y = -3x + 3) and solving for x.
Explanation:The question is asking for the x-intercept of a line with a slope of -3 and a y-intercept of 3.
The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. Here, m = -3 and b = 3.
The x-intercept of a line is the x-coordinate where the line crosses the x-axis. At the x-intercept, the y-coordinate is 0 because it's on the x-axis. Therefore, we set y = 0 in our equation and solve for x: 0 = -3x + 3.
By adding 3x to both sides and then dividing by -3, we find that x = 1. So, the x-intercept of the line is 1(C).
