Answer:
the answers are below
Explanation:
I don't know which one you needed help on
First one: 128x=96 --> x=3/4 so 96 is 75% of 128
Second one: 7^2=49, then use distributive property for the second part (3*5.2) and (3*-2.8)---> 49+15.6-8.4= 56.2
Third one: find the greatest common factor between 7x and 56 (it is 7 since seven can go into 56)---> 7(x+8)
