If the '7t' is supposed to be '7y', then the answer is below
(4y+8)-(7y-12)=11
distribute the negative into the second parenthesis
4y+8-7y+12=11
combine like terms
-3y+20=11
subtract the 20 from both sides
-3y=-9
divide by -3 on both sides
y=3
if it is supposed to be '7t', I'm not sure if there's enough information
Say you have 7/2 as your improper fraction. How many times does 2 go into 7? 3 Times with one left over. Your answer would be
3 1/2
Step-by-step explanation:
for 1 min=9 wraps
for x(unknown minutes)=360 wraps
so I crossed multiply:
9x=360
x=360/9
x=40
so it takes 40 minutes to make 360 wraps
The answer would be 2020 unless you have any specific answer choices.
