Answer:
1. D
2. x=65
Step-by-step explanation:
Hi!
Your answer is D because 78 is 120% of x
120% in decimal point is 1.2.
So it's 1.2x is the same as 120% of x
For question 8:
1.2x=78
Isolate x by divide 1.2 on both sides
78/1.2=65
It would be 10x5 + 3x8= 74
Well 41 divided by 6 is 6.8333333333333 so you just need to subtract .833333333333
