Answer:
A. -5x = -23
Step-by-step explanation:
First you have to simplify the equation - 4(x - 5) + 8x = 9x - 3
-4x + 20 + 8x = 9x -3
9x - 4x = 20 + 3
5x = 23
=> equivalent to answer A.
Answer: 0.185 gallons
Step-by-step explanation:
Divide 5/12 by 2 1/4
First convert the improper fraction to a proper fraction, 2 1/4 = 9/4
5/12 ÷ 9/4
= 5/12 × 4/9
= 5/27 = 0.185
Step-by-step explanation:
Use the quadratic formula

x=\frac{-{\color{#e8710a}{b}} \pm \sqrt{{\color{#e8710a}{b}}^{2}-4{\color{#c92786}{a}}{\color{#129eaf}{c}}}}{2{\color{#c92786}{a}}}
x=2a−b±b2−4ac
Once in standard form, identify a, b and c from the original equation and plug them into the quadratic formula.
