1. Derek adds water to a pool at a rate of 12 gallons per minute and then reduces the

rate to 8 gallons per minute. Derek adds water to the pool for a total of 2 hours. Lett

be the time in hours that he adds water to the pool at the faster rate. Write algebraic

expressions to represent how many minutes he adds water to the pool at each rate.

step-by-step explanation:

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

if i'm not wrong, i would say that the third angle has (72) because the three sides of all triangles have 180 degrees and if we subtract 180 - 62 - 40 = (72) / but i'm not sure about 40 yd.
