To solve this equation with algebra
4/7 = 1/x
(4/7)x = (1/x)x
4x/7 = 1
(4x/7)7 = 1(7)
4x = 7
4x/4 = 7/4
x = 1.75
1.75 yards of fabric are needed to make 1 dress.

Answer:
I think 6.............,..........
357 is your answer because all you do is solve the problem =
So to figure out 10% of this would be to remove the 0. that would be six. since 30÷10 is 3, we have to do 6×3. that would be 18, so 30% of 60 is 18
X=number of hours that the first plane had been traveling.
(x-2)=number of hours that the second plane had been traveling.
we can suggest this equation:
500x+550(x-2)=3100
Now, we can solve this equation:
500x+550(x-2)=3100
500x+550x-1100=3100
1050x=3100+1100
1050x=4200
x=4200/1050
x=4
Answer:
Equation: 500x+550(x-2)=3100
The amount hours, after the first plane left , when the planes will be 3100 miles would be 4 hours.
