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

Can someone help with problems 22, 23 &amp; 25
Sonja [21]

#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!
