The answer is 42 mpg, all you need to do is divide 126/3 or 210/5 and they both equal 42.
im just gonna take the points for falling for that.
Step-by-step explanation:
if we add 18 to both side then it becomes 5x=10x+15 and if we divide by five, x=2x+3
If she needs 1,000 ribbons at 3.72 inches each, She will need 1,000 x 3.72 which equals 3720 inches of ribbon.
This can be converted into feet by taking 3720 inches and dividing by 12 inches in a foot.
This will an answer of 310 feet.
