4m+2m=7-10+15
6m=12
m=12:6
m=2
Since they completed 2/15 miles in 20 mins.
There are 60 mins in an hour so we can multiply they amount of work they did by 3 and that will equal .4
Give me a minute. I’m trying to solve
Y + 8.3 = 12.7.....subtract 8.3 from both sides
y + 8.3 - 8.3 = 12.7 - 8.3...simplify
y = 4.4 <===
u can also check ur answer...
4.4 + 8.3 = 12.7
12.7 = 12.7 ...correct
