Answer:
17.5 yds =r
Step-by-step explanation:
Circumference is given by
C = 2*pi*r
35pi = 2 *pi*r
Divide each side by 2pi
35pi/2pi = 2*pi*r/2pi
17.5 =r
Answer:
f(x) = x³ x>1
Step-by-step explanation:
2 8=2³
3 27=3³
4 64=4³
5 125=5³
f(x) = x³ x>1
Answer:
2(x + 5) = x - 2
⟹ x = -12
Step-by-step explanation:
Doubling the sum of 5 and a number is equal to the same number decreased by 2. What is the equation?
This word problem can be written as:
⟹ 2(x + 5) = x - 2
1. Distribute:
2(x) + 2(5) = x - 2
⟹ 2x + 10 = x - 2
2. Subtract x from both sides:
2x - x + 10 = x - x - 2
⟹ x + 10 = -2
3. Subtract 10 from both sides:
x + 10 - 10 = -2 - 10
⟹ x = -12
4. Check your work:
2(x + 5) = x - 2
2(-12 + 5) = -12 - 2
2(-7) = -20
⟹ -14 = -14 ✔
