It would take 2 hours. To complete the whole lawn you would need:
\frac{8}{8}
To make a whole, so to get that we multiply:
8 \times  \frac{1}{8}  =  \frac{8}{8}
So we use the same number required for the whole lawn, and multiply it times the hours
\frac{1}{4}   \times 8 = 2

i keel asking for the dang answer why wont anyone tell me it a store sells pencils pens and markers that sells two times as many
babunello [35]

Answer:

Pencils = 325 ; Pens = 975 ; Markers = 650

Step-by-step explanation:

Let :

Number of Pencils = x

Number of pens = y

Number of markers = z

2 times as many markers as pencils

z = 2x

3 times as many pens as pencils

y = 3x

x + y + z = 1950

Write z and y in terms of x in the equation :

x + 3x + 2x = 1950

6x = 1950

Divide both sides by 6

6x / 6 = 1950 / 6

x = 325

Number of pencils = 325

Pens = 3 * 325 = 975

Markers = 2 * 325 = 650

Pencils = 325 ; Pens = 975 ; Markers = 650
