Make q the subject of the formula 5(q+p)=4+8
Answer:
q = [tex]\frac{4+3p}{5}[/tex]
Step-by-step explanation:
Given
5(q + p) = 4 + 8p ← distribute the left side
5q + 5p = 4 + 8p ( subtract 5p from both sides )
5q = 4 + 3p ( divide both sides by 5 )
q = [tex]\frac{4+3p}{5}[/tex]
The equation in its simplest form and q as subject is q = (1/5)(4+3p)
What is the meaning of Simplest form ?Reducing any fraction or equation to its simplest form means to to reduce it to a form from where no more factors can be taken common from the numerator and denominator , or the equation is in the form where no more simplification can be done.

Evelyn has three apples to just serve to her friends. if Evelyn served each friend 1/3 of a whole Apple, how many friends can she serve?
Evelyn can serve nine friends with her three apples if she gives each friend 1/3 of an apple by performing a simple multiplication of the number of apples, which is 3, by the reciprocal of 1/3.
Evelyn has three apples and wants to serve each friend 1/3 of a whole apple. To find out how many friends she can serve, we must divide the total number of apples (which is 3) by the fraction each friend receives (which is 1/3).
We perform the division by multiplying the total number of apples by the reciprocal of 1/3, which is 3. So, 3 apples x3 gives us 9. Therefore, Evelyn can serve nine friends.
Understanding fractions can be made easier by relating them to everyday examples. Say, if you have a whole pie, then one-third of this pie represents a slice that is one out of three equal parts of the pie. Knowing that four quarters make one dollar can also make it easy to grasp that four quarters (or four 1/4s) make a whole, just like four 1/4s of a pie would make a full pie.
A restaurant offers 8 appetizers and 6 main courses. In how many ways can a person order a two-course meal?
Answer:
= 48 ways to order a 2-course meal.
Step-by-step explanation:
Number of appetizer choices = 8
Number of main course choices = 6
Number of possible combinations of appetizer and main course
= 6 x 8
= 48 ways to order a 2-course meal.
The number of ways is an illustration of selections and arrangements
There are 48 ways to order a two-course meal
The given parameters are:
[tex]\mathbf{Appetizer = 8}[/tex]
[tex]\mathbf{Main = 6}[/tex]
A person can choose 1 a-piece from each menu.
This means that:
There are 8 ways of selecting appetizers, and 6 ways of selecting the main courses.
So, the number of ways (n) is:
[tex]\mathbf{n = Appetizer \times Main}[/tex]
This gives
[tex]\mathbf{n = 8 \times 6}[/tex]
[tex]\mathbf{n = 48}[/tex]
Hence, there are 48 ways to order a two-course meal

−28x+98=02, x, start superscript, 2, end superscript, minus, 28, x, plus, 98, equals, 0
x = {}x=x, equals
Answer:
7
Step-by-step explanation:
2x² - 28x + 98 = 0
x² - 14x + 49 = 0
(x - 7)² = 0
x = 7
To solve the equation 2x^2 - 28x + 98 = 0, we can use the quadratic formula. After substituting the values into the formula, we simplify the equation and solve for x. The solution is x = 7.
Explanation:Solution:To solve the equation 2x2 - 28x + 98 = 0, we can use the quadratic formula:
x = (-b ± √(b^2 - 4ac)) / (2a)
In this case, a = 2, b = -28, and c = 98. Substituting these values into the formula:
x = (-(-28) ± √((-28)^2 - 4(2)(98))) / (2(2))
Simplifying the equation gives:
x = (28 ± √(784-784)) / 4
Since the term inside the square root is zero, we have:
x = (28 ± √0) / 4
The square root of zero is zero, so:
x = (28 ± 0) / 4
Simplifying further:
x = 28 / 4
x = 7
Therefore, the solution to the equation 2x2 - 28x + 98 = 0 is x = 7.

What are the values of a, b, and c in the quadratic equation 0 = x2 – 3x – 2?
a = , b = 3, c = 2
a = , b = –3, c = –2
a = , b = 3, c = –2
a = , b = –3, c = 2
For this case we have that by definition, a quadratic equation is of the form:
[tex]ax ^ 2 + bx + c = 0[/tex]
Where the roots are given by:
[tex]x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}[/tex]
We have the following equation:
[tex]x ^ 2-3x-2 = 0[/tex]
Then, according to the definition, the values are:
[tex]a = 1\\b = -3\\c = -2[/tex]
Answer:
[tex]a = 1\\b = -3\\c = -2[/tex]
Answer:
The values of a, b, and c in the quadratic equation are:

A spinner has 5 sector's of equal size. The sectors are labeled 1,2,3,4, and 5. the spinner is spun twice.x is the number of times 3 is spun
Answer:
Because the sectors are of equal size, each sector has the same probability of happening.
So for every number, you have a probability of 0.2 of it appearing.
Because you have three odd numbers, the probability to land on an odd number on each spin is 0.6. You can also say that the probability to not have an odd number is 0.4.
So what is the probability to have 0 odd number in two spins?
What is the probability to have 1 odd number in two spins? You can have one odd number on the first or one odd on the second spin, that is why we add the probabilities.
What is the probability to have 2 odd numbers in two spins?
To verify if we did a good job, we add all the probabilities. We should get 1.

The likelihood of spinning a 3 on an equal-segment spinner is 1/5 per spin. When spun twice, the probability of getting 3 both times is 1/25. The variable x, which represents how many times 3 is spun, can therefore be 0, 1, or 2.
Explanation:Your inquiry is related to probability.
Each spin of the spinner is an independent event. This means that the result of the first spin does not influence the result of the second spin. Since the spinner is equally likely to land on any of the 5 sectors, the probability of it landing on 3 (or any given number) is 1 out of 5 or 1/5.
Since the spinner is spun twice, we multiply these probabilities together to find the total probability of spinning a 3 both times. Therefore, the total probability of spinning a 3 twice would be (1/5) * (1/5) = 1/25.
Thus, the variable x, representing the number of times 3 is spun in these two attempts, can be 0, 1, or 2. These are the possible outcomes.

Hello!
The first step you would want to do here is distribute the -3 to inside the parentheses. This can be done by multiplying -3 by what's inside the parentheses. This would make the original equation become:
y + 1 = -3(x - 5)
y + 1 = (-3 * x) - (5 * -3)
Then, complete the multiplication inside the parentheses to get:
y + 1 = -3x + 15
Now, subtract both sides by 1 to isolate the y on the left side.
y + 1 - 1 = -3x + 15 - 1
Therefore, your final answer is:
y = -3x + 14
(it can also be f(x) = -3x + 14, y and f(x) are the same thing in this case)

y=1/2x + 3 y= 3/2x -1
Answer:line a would have a y intercept of three and a slope of 1/2. Line b would have a y intercept of negative one and a slope of 3/2
Step-by-step explanation:line a would start at 3 on the y axis and move up one to the right two. Line b would start at -1 on The y axis and move up three to the right two
The system of equations y=1/2x + 3 and y= 3/2x -1 can be represented as two lines on a graph, the intersection of which indicates any common solution.
Explanation:The system y=1/2x + 3 and y= 3/2x -1 represents two linear equations. These two equations can be graphed out onto the x and y-axis. The first equation y=1/2x + 3 will have a slope of 1/2 and y-intercept of 3, and the second equation y= 3/2x -1 will have a slope of 3/2 and y-intercept of -1.
To graph the first equation, start at the point (0,3) on the y-axis. From there, as the slope is 1/2, for every 2 units you move to the right on the x-axis, you will move 1 unit up on the y-axis.
To graph the second equation, start at the point (0,-1) on the y-axis. As the slope is 3/2, for every 2 units you move to the right on the x-axis, you will move 3 units up on the y-axis.
These lines intersect at their solution, if one exists, that is a common point on both lines.

For a given right triangle side a=76.4 ft and side b=39.3 ft. What is the measure of angle A to the nearest degree?
The measure of angle A in the right triangle with sides a=76.4 ft and b=39.3 ft can be found using the tangent function and is approximately 62 degrees when rounded to the nearest degree.
Explanation:To find the measure of angle A in a right triangle with given sides a=76.4 ft and b=39.3 ft, we can use trigonometric functions. Since side a is opposite to angle A and side b is adjacent to angle A, we will use the tangent function, which is the ratio of the opposite side to the adjacent side. The formula to find the angle is angle A = tan∑(a/b).
Plugging in the values, we get:
angle A = tan∑(76.4/39.3)
By using a calculator, we find:
angle A = tan∑(1.9435) ≈ 62 degrees
Rounded to the nearest degree, the measure of angle A is approximately 62 degrees.
