Given

See attachment for question

Required

Solve

We have:

$\frac{11}{12} - \frac{1}{3}$

Take LCM and solve

$\frac{11}{12} - \frac{1}{3} = \frac{11 - 4}{12}$

$\frac{11}{12} - \frac{1}{3} = \frac{7}{12}$

PLEASE HELP For the expression below, write two other equivalent expressions using different terms. Make sure one is fully simpl

Julli [10]

Given:

The given expression is

$-4(x+2)-2x+4$

To find:

The two other equivalent expressions.

Solution:

We have,

$-4(x+2)-2x+4$

Using distributive property, we get

$=-4(x)-4(2)-2x+4$

$=-4x-8-2x+4$

So, one equivalent expression is $-4x-8-2x+4$ .

On further simplification, we get

$=(-4x-2x)+(-8+4)$

$=6x-4$

Therefore, the second and fully simplified equivalent expression is $6x-4$ .
