Answer: x = 4 and x =1
Step-by-step explanation: by factorization method, use factor 4 and 0. i.e (x-4)(x-0)=0
x=4 and x=0
Answer:
32
Step-by-step explanation:
Divide 24 by 3/4 to find the number.

-1
Step-by-step explanation:
Answer:
(E) 450
Step-by-step explanation:
Let x represent the number of gallons of solution X that must be added to the mix. Then the amount of sugar in the mix is ...
0.20x +0.40·150 = 0.25(150 +x)
0.20x +60 = 37.5 +0.25x . . . eliminate parentheses
22.5 + 0.20x = 0.25x . . . . . . subtract 37.5
22.5 = 0.05x . . . . . . . . . . . . . subtract 0.20x
450 = x . . . . . . . . . . . . . . . . . . multiply by 20
450 gallons of solution X must be added to make a 25% sugar solution.
