Question

I need to find expressions that will show how 5 x 37 can be rewritten using distributive property.
5 x 30 + 7 ---- My answer
5 x 30 + 5 x 7
5 x 40 - 5 x 7
5 x 40 - 5 x 3
*It can be more than one answer*


3u + 7v + 4u = 2v (I have to simplify)
My answer is 7u + 9v because 4+3 and 7 + 2

7u + 5v
&u + 9v
10u - 2v
12uv

Answer 1

37 = 30 + 7


5 x 37 = 5 x ( 30 + 7 ) = 5 x 30 + 5 x 7


3 u + 7 v + 4 u = 2 v Subtract 2 v to both sides

3 u + 7 v + 4 u - 2 v = 2 v - 2 v

3 u + 4 u + 7 v - 2 v = 0

7 u + 5 v = 0

Answer 2

No.

Remember PEMDAS

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
7u = -5v

Answer 3

AND

37 = 40 - 3


5 x 37 = 5 x ( 40 - 3 ) = 5 x 40 - 5 x 3

Answer 4

Thank You! :)
