There are 120 students in the seventh grade. Seventy percent of these students are involved in extracurricular activites. How ma

Tanzania [10]

First, turn 70% into a decimal by dividing 70 by 100.

70% ⇒ 0.70

Multiply 120 by 0.70.

120 × 0.70 = 84

Now we know that 84 students are involved in extracurricular activities. Subtract 84 from 120 to find the amount of students who are <em>not</em> involved in extracurricular activities.

120 - 84 = 36

<h2>Answer:</h2>

<u>36 seventh grade students are not involved in extracurricular activities.</u>

Can someone help me, I don’t get this

I'll break it down for you. Here are the main points:

-has 2 large servings

-made from 9 pints

-x represents how many pints

-y represents how many servings

Now that we know this we can find what each serving comes out to be for example:

$\frac{9}{2\\}$ =4.5 or 4 $\frac{1}{2}$

So for each serving it will come out to be 4.5 pints.

Now that we know this we can figure out the slope to find what the equation which is for example the slope for this equation would be rise over run for example:

$\frac{rise}{run}$ = $\frac{1}{4.5}$ = $\frac{2}{9}$ when simplified.
