Answer:
b) 20 minutes
Step-by-step explanation:
Tom=0.5Mike
in 15 minutes, Tom will have done 1/2 of the lawn
in 15 minutes, Mike will have done 1/4 of the lawn
in 15 minutes, they will have done 3/4 of the lawn
15/3=5 minutes for 1/4 of the lawn to be done
5x4=20 minutes for the entire lawn
Square root of 30 divided by 5
Answer
($17,000-$2,500+$4,900)/60
(19,400)/60
=A. $323.33
One rose is 50 cents, so 2 roses cost $1 ( 50 cents x 2).
2 roses per dollar x 20 dollars = 40 total roses sold.
When they sell $20 dollars they make $6, so that means they pay 20-6 = $14 dollars for the 40 roses.
$14 / 40 roses = 0.35 per rose.
She pays 35 cents per rose.
Let x be the number of hours of nagging groceries spent by Ethan. With this representation, the number of hours for moving lawns will be x + 10. The equation that would let us solve this item is,
6x + 7.50(x + 10) = 129
The value of x from the equation is 4. Thus, the number of hours spent for moving lawns is 14 hours.
