Answer:
y = 32
Step-by-step explanation:
sqrt(2y) +3 = 11
Subtract 3 from each side
sqrt(2y) +3-3 = 11-3
sqrt(2y) = 8
Square each side
(sqrt(2y))^2 = 8^2
2y = 64
Divide by 2
2y/2 = 64/2
y = 32
There is many ways to do this but i did it this way.
180-123.75= 56.25
56.25/5=11.25
=11.25
#22: 10.2 gallons for $2.59 each = 10.2 x 2.59, which rounded is $26.42.
#23: 12 pieces that are 6.45 in wide each = 12 x 6.45, which is 77.4 in.
#25: Aaron started with $38.
$22.47 + $8.53 + $6.50 is $37.50.
38.00 - 37.50 is .50 or 50 cents.
Hope that helps!
