So, first, since 21.8 is a whole thing and you need a part, write x/21.8. Then, compare it to 60/100, or 60%. 100/21.8=4.76. So, divide 60/4.76 and your answer is 12.6.
Glad to help.
-A
I would say. C
Since 100 factor is 10b. And -144 is 12a^2
hope this helps and you get it right
4×2=8 so n=2 and 8+12=20 so ?=12
Answer:
X = 70, y = 21
Step-by-step explanation:
53 + 6y + 1 = 6y + 54
6y + 54 = 180
180 - 54 = 126
6y = 126
126 ÷ 6 = 21
Y = 21
21 × 6 + 1 = 127
127 = 2x - 13
127 + 13 = 140
140 ÷ 2 = 70
X = 70
Opposite angles are congruent and consecutive angles are supplementary.
Hope that helped and have a great day!
