4 0
3x + 12x + 12 = 7
15x + 12 = 7
15x = -5
x = 1/3

3 (1/3) + 4y = 7
1 + 4y = 7
4y = 6
y = 1.5

3 (1/3) + 4 (1.5) = 7

A 'snail's pace is 60 inches per minute. At this rate how long will it take the snail to crawl 120 feet?
True [87]
Ok, so here, we have the unit rate of the snail. Now, we need to set up a proportion.

60/1 = 120/x

Now, cross multiply.

60*x = 120*1

60x= 120

Now divide to solve for x.

60x/60 = 120/60
x = 120/60 
x= 2

Now our final answer is 2.

Final answer:- The snail will take 2 minutes to crawl 120 feet
