E=VIT how would I isolate the “V” variable
Zigmanuir [339]

Answer:

V =\frac{E}{IT}

Step-by-step explanation:

You can isolate the "V" variable by dividing by IT on both sides:

\frac{E}{IT} =\frac{VIT}{IT}

On the left, the IT from the top and bottom cancel, leaving you with just V:

V =\frac{E}{IT}

Emma buys a softball that is 70% off. If the original price is $30, how much does Emma pay?
Korvikt [17]

Answer:

$9

Explanation:

First, we need to find 70% of the original price of $30 using the following equation:

\text{ \$30 }\times70\text{ \% = \$30 }\times\frac{70}{100}=\text{ \$21}

It means that Emma pays $21 less than the original price. So, she pays:

$30 - $21 = $9

Therefore, the answer is $9
