What is the solution to the equation represented by the model below? x= -14
x= -2
x= 2
x= 14

C

Step-by-step explanation:

On the left, we have 3 positive x bars and 8 1s.

Hence, the left can be represented by the following expression:

On the right, we have 4 positive x bars and 6 1s.

Hence, the right can be represented by the following expression:

The two are equivalent. Therefore:

Solve for x. Subtract 6 from both sides:

Subtract 3x from both sides:

Flip:

Hence, our answer is C.

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
