The model below represents an equation. which value of X makes the equation true?

The answer to your question is x = 2

Step-by-step explanation:

To solve this problem just count the number of x and the number of numbers ONE on each side of the equation.

- There are three "x"

- There are 4 number one on the left side equation

- There are 10 number one one the right side of the equation

Equation

                   3x + 4 = 10

Solve for x

                   3x = 10 - 4

                   3x = 6

                     x = 6/3

                    x = 2

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
