Answer: 40%
Step-by-step explanation:
first you symplify your fraction:
12/30 = 2/5
then divide your numerator from your denominator:
2÷5 =0.4
then you convert your decimal into a percentage:
0.4×100=40%
Answer:
x = -9
First, divide both sides by 12 to isolate the expression, x + 11
12(x + 11)/12 = 24/12
x + 11 = 2
Then, subtract 11 from both sides
- 11 - 11
b. 6 cm
Q is the midpoint of PR, so QR = PR/2 = (12 cm)/2 = 6 cm
x = 18
