Which pair shows equivalent expressions?

Alona [7]

Answer:

Option 3

Step-by-step explanation:

We need to find a pair which shows equivalent expressions.

First equation is

$2x+10=-2(x-5)$

$LHS=2x+10$

$RHS=-2(x-5)=-2(x)-2(-5)=-2x+10$

$LHS\neq RHS$

Option 1 is incorrect.

Second equation is

$-2(x+5)=2x-10$

$LHS=-2(x+5)=-2(x)-2(5)=-2x-10$

$RHS=2x-10$

$LHS\neq RHS$

Option 2 is incorrect.

Third equation is

$-2x-10=-2(x+5)$

$LHS=-2x-10$

$RHS=-2(x+5)=-2(x)-2(5)=-2x-10$

$LHS=RHS$

Option 3 is correct.

Fourth equation is

$-2(x–5)=-2X-10$

$LHS=-2(x–5)=-2(x)-2(-5)=-2x+10$

$RHS=-2x-10$

$LHS\neq RHS$

Option 4 is incorrect.

Therefore, the correct option is 3.

John is creating a Thanksgiving display at the store where he works, using only canned pumpkin and canned green beans. He needs

KengaRu [80]

Answer:

90 pumpkin and 36 green beans

Step-by-step explanation:

Because there is a total of 7 parts (5+2) and I divided 126 by 7 and then put five of the 18ns (the quotient of 126 and 7) for pumpkins (so... multiply 18 by 5) then the other to times 18 is 36. And if you add them together, they equal 126.
