Answer:
263.76 feet
Step by step explanation:
Circumference of a circle = pi x d
Given
Diameter d =84 and
Pi = 3.14
Therefore
Circumference = 3.14 x 84
= 263.76 feet
Answer:
x=3
Step-by-step explanation:
9x+5+2x = 38
Combine like terms
9x+2x +5 = 38
11x+5 = 38
Subtract 5 from each side
11x+5-5 = 38-5
11x = 33
Divide each side by 11
11x/11 = 33/11
x = 3
Answer:

Step-by-step explanation:

Step 1. Switch sides.

Step 2. Since the fraction 1/2 multiplies b, multiply both sides by the reciprocal of 1/2 which is 2.


Step 3. Since h is multiplying b, and you want b alone, divide both sides by h.

Answer:

Answer:
X=9
Step-by-step explanation:
2x-7=11
Add 7 each side
2x - 7 +7 =11 + 7
2x=18
Divide by 2 each side
2x/2=18/2
x=9
