Answer:

B = A/5h - b; You could use

B = (A - 5hb)/5h This just puts everything over a common denominator.

Step-by-step explanation:

A = 5h (B + b) Divide both sides by 5h

A/5h = B + b Subtract b from both sides.

A/5h - b = B

Karmin will make $18.4 for working an hour after the increase.

Step-by-step explanation:

Step 1:

First, we need to determine how much Karmin made an hour.

Karmin's hourly rate $= \frac{480}{30} = 16.$

So Karmen made $16 every hour that she worked. She worked for 30 hours and earned $480.

She will get a 15% increase in her hourly rate this month.

Step 2:

We need to determine how much 15% of $16 is.

15% of $16 $= \frac{15}{100} (16) = 0.15 (16)= 2.4.$

So her 15% increase amounts to $2.4.

So the hourly rate for this month $16 + 2.4 = 18.4.$

So Karmin will make $18.4 for working 1 hour.

Solve the quadratic equation.<br>m^2/15 -3 = 2

Radda [10]

The answer is $5 \sqrt{3}$

<h3>Explanation :</h3>

$\frac{ {m}^{2} }{15} - 3 = 2$

$\frac{ {m}^{2} }{15} = 2 + 3$

$\frac{ {m}^{2} }{15} = 5$

${m}^{2} = 5 \times 15$

${m}^{2} = 75$

$m = \sqrt{75}$

$m = \sqrt{25 \times 3}$

$m = \sqrt{25} \times \sqrt{3}$

$m = 5 \sqrt{3}$
