Question

Zari wants to find the dimensions of this parallelogram. She knows that the first step is to find the value of x. Which of these equations will result in the correct value of x?

a) 2x+5=15
b) 3x−2=10
c) 4x=16
d) 5x+3=24

Answer 1

To find the value of x, we need to solve the given equation from the options provided. Option b) 3x−2=10 results in the correct value of x, which is x=4.

Step-by-step explanation:

In order to find the value of x, we need to solve the given equation. Let's go through each option:

1. a) 2x+5=15: Subtracting 5 from both sides gives us 2x=10. Dividing both sides by 2 gives us x=5.
2. b) 3x−2=10: Adding 2 to both sides gives us 3x=12. Dividing both sides by 3 gives us x=4.
3. c) 4x=16: Dividing both sides by 4 gives us x=4.
4. d) 5x+3=24: Subtracting 3 from both sides gives us 5x=21. Dividing both sides by 5 gives us x=4.2.

The correct equation that results in the value of x is option b) 3x−2=10, which gives x=4.
