Answer:
4 movies, $20
Step-by-step explanation:
Given data
Family Video
charges $10 for a monthly membership and
$2.50 per movie
let the number of movies be x
and the charge for x movies be y
y= 10+2.5x----------1
Babe's Movies
charges a $12
membership and $2 per
movie.
let the number of movies be x
and the charge for x movies be y
y= 12+2x----------2
equate 1 and 2
10+2.5x= 12+2x
collect like terms
12-10= 2.5x-2x
2= 0.5x
x= 2/0.5
x= 4 movies
put x= 4 in equation 1 or 2
y= 12+2x----------2
y= 12+2*4
y= 12+8
y= $20

Three more than twice the number is 25
The number you're looking for is 25. Simply work backwards.
25 - 3 (three more...) = 22
22 ÷ 2 (twice the number) = 11
Answer:
<h3>
8, 9, 10</h3>
Step-by-step explanation:
x ← the smallest integer
x+1 ← the middle integer
x+2 ← the largest integer
3x ← three times the smallest
x+2 + 14 ← 14 more than the largest
3x = x+2 + 14
-x -x
2x = 16
÷2 ÷2
x = 8
x+1 = 8+1 = 9
x+2 = 8+2 = 10
Check: 3×8 = 24; 24-14 = 10
