A sparkling-water distributor wants to make up 200 gal of sparkling water to sell for $ 5.00 per gallon. She wishes to mix three grades of water selling for $10.00, $1.00, and $4.50 per gallon, respectively. She must use twice as much of the $4.50 water as the $ 1.00 comma water. How many gallons of each should she use?

x=50

y=50

z=100

Step-by-step explanation:

Let x = $10

y = $1

z = $4.5

2y=z

5 * 200 = 1000 Dollars wanted

1000 = 10x + y + 4.5z

variables represent number of gallons of each type

1000 = 10x + y + 4.5(2y)      sub z for y

x=50

y=50

z=100

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."

the answer is d. (1.2, -4.7) on edgn

hope this !
