Which of the expressions are equivalent to the one below? Check all that apply.
7.(6+3)
O A. 7.6+7.3
I B. 7.3 +7.6
O C. 7.9
1 D. 7.18

Step-by-step explanation:

The distributive property and the commutative property of addition both apply here.

  Distributive property: a(b+c) = ab +ac

For a=7, b=6, c=3, this becomes ...

  7(6+3) = 7·6 +7·3 . . . . . matches A

The commutative property of addition says ...

  a + b = b + a

For a=7·6 and b=7·3, this becomes ...

  7·6 + 7·3 = 7·3 + 7·6 . . . . . matches B

Of course, the expression can be partially evaluated:

  7(6 +3) = 7·9 . . . . . matches C

answer: the answer is 5/22

step-by-step explanation: if you subtract 17 from 22 the answer is 5 therefore the remainder of students are female

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
