Step-by-step explanation:
C=πd
find diameter:
small= 15 x 15= 225
large= 24 x 24= 576
multiply:
225 x 3.14= 706.5
576 x 3.14= 1808.64
ratio:
706.5/1808.64
reduce:
25/64
The answer is 2(x+4)-5x+2 .
Step by step:
Distribute the 2 through the parentheses--> 2x+8 -5x + 2
Then collect the like terms:
-3x+8+2
Then add 8 and the 2
-3x + 10
Answer:
x = 7 / 2
Step-by-step explanation:
5(2x - 9) + 3 = -7 ---------- subtract 3 from both sides
5(2x - 9) + 3 - 3 = -7 - 3
5(2x - 9) = -10 ------ divide both side by 5
2x - 9 = -2 ---------- add 9 to both sides
2x - 9 + 9 = -2 + 9
2x = 7
x = 7 / 2
Answer:
