Hello from MrBillDoesMath!
Answer:
r = C/6.28
Discussion:
Note that C = 2 * Pi * r is the exact formula. As Pi is approximately 3.14, the given formula, C = 2 (3.14) r, is an approximation. Solving it for r:
C = 2(3.14) r => as 2 * 3.14 = 6.28
C = 6.28 r => divide both sides by 6.28
r ( 6.28/6.28) = C/6.28 => as 6.28/6.28 = 1
r = C/6.28
Thank you,
MrB
you need to distribute the 5. multiply each term in the parentheses by 5:
5(1) + 5(3x)
5 + 15x
Forks :
20 x 12 = 240
Spoons:
10 x 12 = 120
Knives :
5 x 10 = 50
Paper plates :
175
Total :
175 + 50 + 120 + 240 = 585
