How long does it take her to do a lawn? If it took her 5 hours for 1 lawn then it would be $840 for twelve lawns.


She is getting paid $14 an hour.

I think there's something missing but I will elaborate as much as I can.

Let's find out how much she's paid an hour.

70 ÷ 5 = 14

Lindsey makes $14 an hour.

We must know how much she makes in 12 hours.

14 × 12 = 168

Lindsey earns $168.

an artificial lake is in the shape of a rectangle and has an area of 9/20 square mile. the width of the lake is 1/5 the length o
Gnom [1K]
X=length
y=width
Area (rectangle)=length x width
we suggest this system of  equations:
y=x/5
xy=9/20
solve this system of equations by substitution method:
x(x/5)=9/20
x²/5=9/20
Least common multiple=20
4x²=9
x²=9/4
x=⁺₋√(9/4)
we have two solutions:
x₁=-3/2   it does not validate
x₂=3/2    ⇒y=x/5=(3/2)/5=3/10

The dimensions of the lake are:
lengh=3/2 miles
width=3/10 miles

to check:
Area=3/2 miles x 3/10 miles=9/20 miles².
width is 1/5 the length of the lake ⇒  3/10 miles=(3/2) /5 miles
