k-k+k-3 what is this answer?
Answer:
k-3
Step-by-step explanation:
Eliminate the opposites
K-k+k3
= k-3
The given algebraic expression simplifies to k - 3. This means, for any value of 'k', the result would be 'k' minus 3.
Explanation:The problem provided is k-k+k-3. In this case, 'k' is a variable, which is essentially an unknown number. When you subtract a variable (k) from itself, you get zero. Therefore, k - k equals zero. Adding k back again, we return to k itself. Hence, k - k + k - 3 simplifies to k - 3. That is, whatever value 'k' is, you have to subtract 3 from it to solve this equation.

Martina is 3 inches less than twice as tall as her little brother . Write an expression for Martina’s height . How tall is Martina if her little brother is 28 inches tall?
Answer:
Expression: 2x-3
Martina's height if her little brother is 28 inches: 53 inches
Step-by-step explanation:
To write the expression, first read the problem. Martina is twice as tall as her little brother, minus 3. If x represents Martina's little brother's height, the equation will be 2x-3, since she's 3 inches shorter than twice the height of her little brother.
The question says that her little brother is 28 inches tall. Since x represents Martina's little brother's height, simply plug x into our expression.
2x-3
2(28)-3
56-3
53
Therefore, if Martina's little brother was 28 inches tall, Martina would be 53 inches tall. i hope this helps! :)
This answer involves the creation of a mathematical expression based on the given information and substituting the known value to find the unknown variable. The mathematical expression is 'Martina's Height = 2 * (Brother's height) - 3 inches.' When the brother's height is 28 inches, we get Martina's height as 53 inches.
Explanation:The question relates to writing and solving expressions in Mathematics. To find how tall Martina is, we need to first write down an expression depicting the statement. According to the given statement, we can write:
Martina's Height = 2 * (Brother's height) - 3 inches
If her little brother is 28 inches tall, we substitute 28 into the expression:
Martina's Height = 2 * (28) - 3 inches
This implies:
Martina's Height = 56 - 3 inches = 53 inches
Therefore, Martina is 53 inches tall if her little brother is 28 inches tall.

Which rule describes the translation?
C would be my guess, I just take the first letter w/o the apostrophe, and move it by each rule and see if it matches up with the letter with the apostrophe.
Answer:
C, (x,y) → (x + 8, y - 3)
Step-by-step explanation:
we can locate one point on the shape and use that as a reference point to see where it goes.
ABCD is the original shape, while A'B'C'D' is the translated shape
we start at ABCD, for this shape i picked the point B to follow
we count how many units the point B goes in order to get to B'. we start on the x axis, and see that it goes 8 units to the right. this is an increase, as its rising in value
from there, we follow the y axis, moving 3 units down. this is a decrease, as we are going 3 units down
so according to what we have moved in order to get from B to B', we moved 8 to the right so we have x + 8, with x being the x-coordinate the point was previously on. we have moved 3 units down to get from B to B', which is y - 3, with y being the y-coordinate the point was on previously
the answer to this is C, (x,y) → (x + 8, y - 3)

Jorge is building a table out of boards that are 3.75 inches wide he wants the table to be at least 36 inches wide what is the least number of boards he can use
Answer:
10
Step-by-step explanation:
If a board is 3.75 inches wide and he wants the table to be at least 36 inches wide, then we need to use the rule of three:
If a 1 board ---------------------------> 3.75 inches wide
x ---------------------------> 36 inches wide
x = (36 inches wide * 1 board)/3.75
x= 9.6 boards.
Like we cannot buy 9.6 boards, then we conclude that the least number of boards he can use is 10.
Four times a number, decreased by eight equals twelve. What is the number?
Let the number be x.
4x - 8 =12
4x =12 +8 ( you bring the eight over to the 12, it becomes positive )
4x = 20
x = 20÷4
x = 5
The problem is a basic algebra equation. It translates to 4x - 8 = 12, which can be solved by adding 8 to both sides and then dividing by 4 to get x=5. The answer is 5.
Explanation:The subject of this question is Mathematics, specifically algebra. To solve this equation, start by translating the problem into a mathematical expression. This can be done as follows: 4 times a number is represented as 4x, then decreased by eight is -8 and the equation equals twelve (12).
Therefore, the equation is 4x - 8 = 12. To solve for x, you can start by adding 8 to both sides of the equation obtaining 4x = 20. Lastly, divide both sides by 4 to find x, which gives x = 5.
Therefore, the number that meets the condition '4 times a number, decreased by 8 equals 12' is 5.

Given a slope of 1/2 and a y-intercept of -4. What is the equation of the line in slope intercept form?
Answer:y=\frac{1}{2} x-4
Step-by-step explanation:
Slope intercept form of the equation of a line is y = mx+b where m is the slope and b is the y intercept. Plugging in 1/2 for m and -4 for b gives y = 1/2x + (-4) then simplifying adding a negative means subtracting.
The equation of the line is y = (1/2)x - 4, where the slope is 1/2 and the y-intercept is -4.
Explanation:
The equation of a line in slope-intercept form is y = mx + b, where m represents the slope and b represents the y-intercept.
In this case, the slope is 1/2 and the y-intercept is -4, so the equation of the line is y = (1/2)x - 4.
The slope of 1/2 means that for every increase of 1 on the horizontal axis, there is a corresponding increase of 1/2 on the vertical axis.

Compare the two leagues and predict which league would be more likely to win a game.
Interpreting Data( written response)
Answer:
The team from the second league would be more likey to win becasue teams in taht league have more consistent, and mostly greater, numbers of home runs and winning games. Data for teams in the second league also do not show any outliers.
Comparing the data of wins and home runs for the 2 leagues given in the table, we can predict that;
The second league will be more likely to win a game than the first league.
This is about data comparisons and interpretation.
Now, from the 2 tables, we see 2 columns namely HR and W;
HR; This means Home Runs. This is gotten by hitting the ball in a baseball game over the outfield fence that stands in-between the foul poles and does not touch the ground first before going over the outfield fence. This means more home runs denotes more points.
W; This is the number of wins each team possesses. The more the games won, the more the points and the more chances of winning the league.
Now, from the above analysis, we have seen that More HR( Home runs) and more W(Wins) means more points and better chances of winning the league.
Comparing the two leagues, it is clear that second league has teams with more Home runs and more Wins than the first League.
In conclusion, we can say that The second league will be more likely to win a game than the first league.

How many solutions does 3/4(24-16x)=-2/3(18x-27) have?
Answer:
Step-by-step explanation:
Answer: An infinite number
Multiply both sides of the equation by 12
12 [ 3/4 (24 - 16x) = - 2/3 (18x - 27) ]
3*3(24 - 16x) = - 2 * 4 (18x - 27)
9 ( 24 - 16x) = - 8(18x - 27)
Remove the brackets.
216 - 144x = - 144x + 216
Any value for x will preserve the equality. Nice problem.
Final answer:
The equation 3/4(24-16x)=-2/3(18x-27) simplifies to an identity, implying that there are infinitely many solutions for x. Values like x=3 or x=-7 will satisfy the equation, which is a characteristic of an identity.
Explanation:
The equation in question is 3/4(24-16x)=-2/3(18x-27). To find the number of solutions, we begin by simplifying both sides and then solving for x. Let's do this step by step:
Multiply each term inside the parentheses by the fractions in front of them: 18 - 12x = -12x + 18.Notice that both sides of the equation are the same, which means every value of x is a solution. This type of equation is known as an identity.Since this is an identity, there are infinitely many solutions for x.As a check, we can attempt to substitute possible values for x such as x=3 or x=-7 into the equation, and we'll find that they satisfy the equation, confirming our result.

A smart phone manufacturer uses 10 ounces of gold circuitry to make 5,200 smart phones. If they made 7,800 smart phones last month and gold is valued at $1,300 per ounce, what is the value of gold used last month? A) $19,500 B) $20,500 C) $21,500 D) $22,500
Answer:
Its 19,500
Step-by-step explanation:
Answer:
Option A. $19,500
Step-by-step explanation:
A smart phone manufacturer uses 10 ounces of gold circuitry to make 5,200 smartphones.
We will solve this problem by unitary method.
In 5200 smartphones use of gold = 10 ounces
in 1 smartphone use of gold = [tex]\frac{10}{5200}[/tex] = 0.001923 ounces
In 7,800 smartphones, use of gold = 0.001923 × 7800 = 14.999 ounces rounded to 15 ounces of gold
Last month the value of 1 ounce gold is $1,300
The value of 15 ounces = 1,300 × 15 = $19,500
The value of gold used last month is $19,500.

Answer:
Step-by-step explanation:
It looks like you are using the sine law.
23/Sin(85) = x / sin(55) Cross multiply
23*sin(55) = x * sin(85)
23*sin(55)/sin(85) = x
None of these answers look correct. One thing you could try is
sin(85) = cos(90 - 85)
sin(85) = cos(5)
That would give you
x = sin(55)*cos(5)
