Answer:
a = 4
Step-by-step explanation:
Simplify both sides of the equation.
−296=−8(8a+5)
−296=(−8)(8a)+(−8)(5)
−296=−64a+−40
−296=−64a−40
Flip the equation
−64a−40=−296
Add 40 to both sides
−64a−40+40=−296+40
−64a=−256
Divide both sides by -64
(−64a
) / (−64) = (−256) / (−64)
a = 4
C = 2πr
141.3 = 2(3.14)r
141.3 = 6.28r
22.5 = r
(a) One possibility is 8.45
Rounded to the nearest integer = 8
Rounded to the nearest tenth = 8.5
And rounding this to the nearest integer = 9
(b) The possible numbers are 8.45 to 8.49, inclusively
