Nancy shot a 16 on 4 holes of golf. At this rate, what can she expect her score to be if she plays 18 hole? Round to the nearest whole number.

108.

Step-by-step explanation:

"At this rate, ..." means we're to assume Nancy's score is proportional to the number of holes:

 score/18 = 24/4

Multiplying by 18, we get ...

 score = 18(24/4) = 18(6) = 108

Nancy can expect a score of 108 on 18 holes.

(if this isn't right, tell me and I will make sure to recheck my work :).

72

Step-by-step explanation:

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,

step-by-step explanation:

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
