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.

What operations would the set of quadratics be closed under? For each operation, explainwhy it is closed or provide an example showing that it isn’t.Type your response here:x^2-1+(x^2+2x+1)=2x^2+2x closed under addition.(x^2-1)-(x^2+2x+1)=-2x-2 not a quadratic(x^2-1)(x^2+2x+1)=x^4+2x^3-2x-1 no above degree 2(x^2+2x+1)/(x^2-1)=1+(3x+1)/(x^2+2x+1) not a quadratich. Is there a set of expressions that would be closed under all four operations? Explain.Type your response here: Polynomials with a degree of 0, real numbers, andrational numbers.
