Cheryl is organizing her movie collection. If each movie case is 3/4 inch wide, how many movies can fit on a shelf 5 1/4 feet wide?

3

Step-by-step explanation:

size of the shelf= 5 1/4 = 21/4

size of movie case = 3/4

The number of movie cases that will fit in a 5 1/4 ft shelf = 21/4 ÷3/4

= 21/4 *4/3

= 7

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

2x^2+5x+17
