You can now 800 square feet of lawn in 15 minutes at this rate how many minutes will it take you to mow a lawn that measures 600
frutty [35]
Ok so assuming you don't get tired and the rate stays the same
rate=amountwork/timeitdonein

rate=800/15

euals
6000/time

800/15=6000/time
simlify for ease
160/3=6000/time
multiply both sides by 3time
160time=18000
divide both sides by 160
time=112.5

means 112.5 minutes or 1hour, 52 minutes, 30 seconds

Simplify 3(4x + 6) - 9x.<br><br> -15x + 18<br> 3x + 18<br> 3x + 6<br> 12x + 18 - 9x
Kamila [148]
Hi there!

To simplify this equation we first need to distribute.

(3)(4x) + (3)(6) + - 9x
= 12x +18 + - 9x

Next, combine like terms.

= 12x + 18 + - 9x
= (12x + - 9x) + (18)
= 3x + 18

In simplified form, 3 (4x + 6) - 9x is 3x + 18.

Hope this helps!
