Answer:
50
Step-by-step explanation:
find a number that is 16 less than twice a number is decrease is 84
so if i get this right it is:
84 = 2x-16?
if so we do the following:
84+16 = 2x (Move the variables to one side and the numbers to the other)
100 = 2x (simplify)
50 = x (divide each side)
Answer:
9, if you round to 2 Decimal Places.
(C = 18π = 18 × π = 56.54 (2 DP))
r = C ÷ 2π
= 56.54 ÷ 2 × π ≈ 9
15 more than half -12 = 9 or -6 + 15 = 9
Dotted line and Shade below are two solutions to this.
Hope this helps!!
