Answer:
4a+7 over 2 = b.
Step-by-step explanation:
First add 7 to both sides to get 2b by its self so you will have 4a+7=2b. Then, to get B by itself, divided both sides of the equation by to, so you will have 4a+7 (over 2) = B.

Answer:
1.38 x 10^4 that’s it in scientific notation
Step-by-step explanation:
Associative property is dealing with parentahsees and orders
it is
a(bc)=(ab)c and
a+(b+c)=(a+b)+c
so we want the multiplication one
given
(10)(5x)(7)
we can arragnge these a number of ways (we should use commutative property, but whatever)
first one works, the 7 was moved to front
2nd is wrong, that is a wierd version of the distributive
3rd is right, 5x was moved to the front
4th is wack, no bueno
answer is 1st and 3rd options
135 mph
because if i divide 270/2 it gives me 135
hope this helps.
