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
B)
2x6= 12
2x7= 14
2x8= 16
2x8= 18
The area of the triangle should be 20. Try that out
