7x - 3x = 24

7x - 3x = 24
The 7x and the 3x are both like terms, so they can be combined. 7 - 3 is 4, so the equation turns into
4x = 24
Now, you want to get the x alone, so you divide both sides by 4 because it is the opposite of multiplication. 24 divided by 4 is 6, so
x = 6

Answer:

x=3

Step-by-step explanation:

7x-3x=24

subtract 7 and 3 you'll get 4x=24

4x=24

divide each side by 4

x=3

Meiko is hanging a picture collage on her wall. The dimensions of the collage are shown in the diagram. She plans to cover

alexira [117]

Answer: $\frac{A_{collage}}{15.75\ in^2}$

Step-by-step explanation:

Since you did not attach the diagram and I don't know the dimensions of the collage, I will give you a general explanation of the procedure you need to use in order to solve the exercise:

1. You need to use the formula for calculate the area of a rectangle:

$A=lw$

Where "l" is the length and "w" is the width.

2. Using the formula, you must calculate the area of an small picture.

You know that its length is 4.5 inches and its width is 3.5 inches. Therefore, its area is:

$A_{picture}=(4.5\ in)(3.5\ in)\\\\A_{picture}=15.75\ in^2$

3. Calculate the area of the collage using the formula:

$A_{collage}=(l_{collage})(w_{collage})$

4. Finally, divide the area of the collage by the area of an small picture in order to find the number of small pictures that will fit within the collage:

$\frac{A_{collage}}{15.75\ in^2}$

Answer:

It would be B.

Step-by-step explanation:

This is because adding a negative exponent onto a number is telling you how many times you have to divide it by. So in this case, it would be the equation 1 / 2^4 to solve it.

Let mA = 40°. If B is a complement of A, and C is a supplement of B, find these measures.

nasty-shy [4]

If B is a complement of A this means that the sum of the measures of A and B is 90 degrees.

mA + mB = 90
mB =90 - mA
mB = 90 - 40 = 50

Thus, the measure of angle B is 50 degrees.

If C is a supplement of B then, the sum of the measures of B and C is 180 degrees.
mC + mB = 180
mC = 180 - mB
mC = 180 - 50 = 130

Therefore, the measure of angle C is 130 degrees.
