Answer:
Step-by-step explanation:
<u>Use ratios:</u>
- 30/20 = (x + 5)/(36 - 20)
- 3/2 = (x + 5)/16
- 2(x + 5) = 3(16)
- 2x + 10 = 48
- 2x = 38
- x = 19
Answer:
43
Step-by-step explanation:
She has distributed the bracket incorrectly
(64 + 5) - 0.2(- 20 + 10)
= (69) - 0.2 (- 10)
=34.5 + 2
= 36.5
28(pi) is the same thing is (pi)(diameter)
so 28/2 is 14
14 is the radius
