Answer:

B. 40, 51.5, 88.5

Step-by-step explanation:

(5x - 4) + (2x + 3) + (3x- 4) = 180

10x - 5 = 180

10x = 185

x= 18.5

Substitute

5(18.5) - 4 = 88.5

2(18.5) + 3 = 40

3(18.5) - 4 = 51.5

16+5x=8x-5 What would the variable be?
11111nata11111 [884]
16+5x =8x-5

Reorder the terms
16+5x = -5+8x
Solving for variable for x

Move all terms containing x to the left, all other terms to the right.
Add -8x to each side of the equation.
16+ -3x = -5 + 8x + -8x

Combine like terms: 5x + -8x=-3x
16+-3x = -5 + 8x + -8x

Combine like terms: 8x + -8x = 0
16+-3x = -5 + 0
16+ -3x = -5

Add -16 to each side of the equation
16+-16 + -3x = -5 + 16

Combine like terms: 16+ -16 = 0
0 + -3x =-5 + -16
-3x = -5 + -16

combine like terms: -5 + -16 = -21
-3x = -21
Divide each side by -3
x=7

Answer:

<em>Addition Property of Equality</em>

Step-by-step explanation:

<u>System of Equations</u>

When two equations are given and two variables are unknown in both equations, then we can solve the system in several ways.

One method consists in adding both equations term by term and eliminate one of the variables. That property is called the addition of equalities. Let's consider the equations given in the problem:

5x+4y=-2\\2x-4y=6

If we add both equations, we have

5x+4y+2x-4y=-2+6

Simplifying

7x=4

By adding both equations we managed to eliminate the variable y and could easily find the value of x

x=4/7

LekaFEV [45]
To find the measure of a singular window we need to find the area which is length times width. so that's 2.75(4) which is 11 square feet. However, Kevin has four windows which means he needs 11(4) square feet for all the windows. Which would mean Kevin needs 44 sqaure feet.
