Question

What is the value of w?

5(9 − 3) = w • 9 – 5 • 3

Answer 1

what will the expansion of
5(9-3) look like

Answer 2

Answer 3

30

Answer 4

yea okay but i mean just writing it out in general

Answer 5

like the middle step

Answer 6

5(9-3)=5*9 - 5*3

Answer 7

cuz of 9-3=6 times 5=30

Answer 8

okay dont simplify the inside now, just write out distributive law

Answer 9

5(9 − 3) = w • 9 – 5 • 3
5(9 − 3) = 5 * 9 - 5 * 3 <------- from distributive law of multiplication

can you see what w has to be now

Answer 14

by its self?

Answer 15

30=w • 9 – 5 • 3
hmm okay

Answer 16

and yes i do know that

Answer 17

look try plugging in numbers to get a feel for it

Answer 18

Answer 32

i hate math

Answer 33

5(6)= w(4)(3)
30=12w
30/12=w but 30/12 cant get enterd in the bx so we divide?

Answer 34

wich is 2.5

Answer 35

but we can break it down more to 1 by dividing them right?
