Example 1
evaluate the expression (5 + 7) + 2x3- (8 + 1).
(5 + 7) + 2 x 3 – (8 + 1) = 12 - 2x3- (8 + 1) add inside the left parentheses.
= 12 - 2 x 3-9 add inside the remaining parentheses
= 6 x 3 - 9
divide.
= 18 - 9
multiply
subtract.

you meant circumference well the answer is:

17.27876 miles

area is 23.7583

the radius is 2.75 miles

for every 3 steps of anna's steps , todd made 5 steps .

so, there will be ratio i.e.

so, the number of steps anna walk = 3x

the number of steps todd walk = 5x

according to question,

so,

number of steps anna walk is given by

number of   steps todd walk is given by
