8. Riverside has 270 seventh grade students, and its ratio of boys to girls is 5:4. Salem has
180 seventh grade students, and its ratio of boys to girls is 4:5. The two towns hold a carnival, and all
seventh grade students from both towns attend. How many seventh grade students at the carnival are
girls?
[A] 220
[B] 225
[C] 230
[D] 100

the answer is 37

step-by-step explanation:

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."

there still no table
