What I would do for this problem, is move all the terms that don't contain m to the right side, and then solve.
m = 4/5.

You have to isolate the variable. This is how you do it.

-40= 30m - 16
add 16 to both sides
-24= 30m
divide 30 from both sides
-24/30=m
simplify
-4/5=m
or as a decimal
-0.8=m
I hope this helps love! :)

Ethan spent 12.5% of the money in his pocket on dinner. His dinner cost $15.25. How much did he have in his pocket? Group of ans

Tju [1.3M]

Answer:

$122

Step-by-step explanation:

Let total money in his pocket = $ x

12.5% of x = $ 15.25

$\frac{12.5}{100}*x= 15.25$

Multiply both sides by 100

12.5 *x = 15.25*100

125.5 *x = 1525

Divide both sides by 125.5

$x = \frac{1525}{12.5}\\\\$

x = $ 122

Solve for x. -ax+3b>5

Ann [662]

This is a problem of inequalities. An inequality stands for the relationship between two values when they are different. In this problem, we need to solve for x. So, we have that:

$-ax+3b>5$

Subtracting 3b from each side of the equation, we have:

$-ax+3b \mathbf{-3b}>5 \mathbf{-3b} \\ \\ -ax>5-3b$

Multiplying by $-\frac{1}{a}$ the direction of the inequality changes if $a$ is greater than zero, so we have that solving for x the result is:

$-\frac{1}{a}(-ax)$
