A car rental company charges a daily rate of $ 24 plus $ 0.10 per mile for a certain car. Suppose that you rent that car for a d

Mariulka [41]

Answer: 130 miles

Explanation: make an equation. 24 + 0.10m = 37.00. subtract 24 from both sides leaving m for miles on one side. 0.10m = 13.00. now divide both sides by 0.10 leaving m by itself and making the equation m = 130.

PLEASE HELP, MATH, PLEASE<br>Solve for n: n+5/16 = -1

Anit [1.1K]

$\tt Step-by-step~explanation:$

To solve for n, we have to isolate n. To do so, we move all the terms that are not n to one side of the equation, and leave n on the other side.

$\tt Steps:$

Equation: n + 5/16 = -1

Subtract 5/16 on both sides to bring it to the right side of the equation.

$\tt n+5/16-5/16=-1-5/16\\\\n=-\frac{21}{16}~or~-1\frac{5}{16}$

$\Large\boxed{\tt Our~final~answer:~n=-\frac{21}{16}~or~-1\frac{5}{16} }$
