X + y = 47
x = y + 13
y + 13 + y = 47
2y + 13 = 47
2y = 47 - 13
2y = 34
y = 34/2
y = 17
x = y + 13
x = 17 + 13
x = 30.....longer piece is 30 inches
Answer:
$23.60
Explanation:
you can make an equation out of the information provided! it will look something like:
12.5(.7)+13.5(1.1)
(12.5 is the amount of green ribbon and .7 is the cost per foot, so you would multiply them to find the total cost of the ribbon. do the same thing for the polka dot ribbon; 13.5 feet times 1.1, the cost per foot, will give u the total cost of polka dot ribbon. then, add them together for the total cost of both ribbons!!)
12.5×.7=8.75
13.5×1.1=14.85
8.75+11.85=23.6, or $23.60!!
