Answer:
x=100
Step-by-step explanation:
(2x+8)+(71-x)=180
2x+8+71-x=180
x+80=180
x=180-80
x=100
Answer:
w = 18; l = 62
Step-by-step explanation:
The formula for perimeter of a rectangle is P = 2l + 2w, where l represents length and w represents width
We know that the length can be found using the equation l = 3w + 8
Plugging this in for l in the original formula for perimeter gives us 160 = 2 * (3w + 8) + 2w
160 = 6w + 16 + 2w
160 = 8w + 16
144 = 8w
18 = w
Plugging 18 in for the second equation gives us 3 * 18 = 54 + 8 = 62 = l
Answer:
x = y / 3.2
Step-by-step explanation:
Given:
y = 3.2x
Where
y = cost for a taxi ride during peak hours (in dollars)
x = cost for a taxi ride during off-peak hours (in dollars)
Solve the equation for x.
y = 3.2x
Divide both sides by 3.2
y / 3.2 = 3.2x / 3.2
y / 3.2 = x
x = y / 3.2
This means,
Cost for a taxi ride during off-peak hours (in dollars) = Cost for a taxi ride during peak hours (in dollars) / 3.2
