Answer:
9
Step-by-step explanation:
Adding polynomials causes like terms to be combined. The sum cannot have a degree higher than the degree of any of the terms in the sum. If the degree of f(x) is 8, then the degree of g(x) must be 9 in order for the sum to be of degree 9.
Answer:
1 quart of oil is $2.
Step-by-step explanation:
Represent the problem with equations.
let x be a quart of oil and g be a gallon of gasoline
(1) 24.5 = 10g + x
(2) 22 = 8g + 2x
We need to solve this system of equations to get x.
I can solve by elimination by making both equations have 2x.
Multiply equation (1) by 2. Equation (2) remains the same.
(1) --> 49 = 20g + 2x
(2) 22 = 8g + 2x
Subtract (2) from (1) to get:
27 = 12g <= isolate g
g = 27/12
g = 9/4
Substitute g = 9/4 in (2)
22 = 8g + 2x
22 = 8(9/4) + 2x
Now simplify and isolate x.
22 = 18 + 2x
2x = 4
x = 2
x represents one quart of oil.
Therefore, one quart of oil is $2.
