i know 73.25 x 3 = 219.75ft. i don't understand how to convert the .75 into inches?

219 ft, 9 inches

Step-by-step explanation:

73.25 yards of cable to feet and inches

1 yard = 3 ft

Therefore;

73.25 yards is equal to;

73.25 x 3 = 219.75 ft

1 ft =12 inches

Thus; 0.75 ft is equal to;

0.75 × 12 =9 inches

Hence; 73.25 yards is equal to 219 ft and 9 inches

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
