4 quarts per 1 gallon
300/4 = 75 gallons per hour
Answer:
C = -N(P - R)
Step-by-step explanation:
Rearrange the equation so that it is equal to C.
P = R - C/N
P - R = -C/N
-N(P - R) = C
C = -N(P - R)
Answer:a.100+(hx25)
b.120+(hx20)
c.4 hours
h=hours
Step-by-step explanation:
Answer:
Solutions are (6,3) and (-2,3).
Step-by-step explanation:
From the first equation given we can write:
substituting for
in the second equation given we get


∴ y=3
Putting y=3 in the first equation we get

x-2 = ±4
Hence x=6 or x=-2.
