Mr. Shahoian need to purchase 9 pieces of fencing.

Step-by-step explanation:

Given: Length of fencing around the flower beds in his backyard = 166.25 ft

The fencing is sold in lengths of 19 ft each.

Number of pieces of fencing = (Length of fencing ) ÷ (19)

i.e. Number of pieces of fencing = 166.25 ÷ 19

= 8.75 ≈ 9

Hence, Mr. Shahoian need to purchase 9 pieces of fencing.

take it another

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
