11 and 3/8-1/8=11 and 2/8=11 and 1/4
3/4 times xbags=11 and 1/4
convert 11 and 1/4 to improper faction
11 and 1/4=11+1/4=44/4+1/4=45/4
3/4 times xbags=45/4
times both sides by 4/3 (to clear fraction since 3/4 times 4/3=12/12=1)
xbags=180/12
xbags=15
she could fill 15 bags

Answer: The following three equations could be used to determine the rate:
x*(time there) = 3 miles
(x+1)*(time back) = 3 miles
(time there) + (time back) = 2.5 hr
Step by step (including the actual solution x):
Equation for the trip there:
x*(time there) = 3 miles
Equation for the trip back:
(x+1)*(time back) = 3 miles
And we also know that:
(time there) + (time back) = 2.5 hr
So we have three equations with three unknowns and can solve for x. Let us call
(time there): t1
(time back): t2
The solution (I skipped the gory details of solving, but you can verify by plugging the values back into the equations) is
Rate x = 2 miles/hour
(time there) = 1.5 hours
(time back) = 1 hour
Answer:
You're correct. x= 28
Step-by-step explanation:
2x - 49 + x + 90 + 55 = 180
2x - 49 + x + 145 = 180
3x - 49 + 145 = 180
3x + 96 = 180
3x + 96 - 96 = 180 - 96
3x = 84
3x/3 = 84/3
x= 28
