If 25 students took an exam and 4 of them failed, what percent of them passed?
lisabon 2012 [21]

If 25 students took an exam and 4 of the students that took the exam failed, what percent of the students passed?

To find out how many students passed, we can subtract 4 from 25 and we will get a difference of 21.

The fraction \frac{21}{25} represents the number of students who passed the exam out of all the students.

To find out what percent of the students passed, we can turn \frac{21}{25} into a percent.

21 ÷ 25 = 0.84

0.84 × 100 = 84%

Therefore, 84% of the students who took the exam passed.

If ||M and M6 = 4X - 15 and m7 = x + 30 then m 6 =​
TEA [102]

Answer:

<h2>15</h2>

Step-by-step explanation:

∠6 and ∠7 are Alternate Interior Angles.

The lines l and m are parallel, therefore ∠6 and ∠7 are congruent.

m∠6 = m∠7 → 4x - 15 = x + 30        <em>add 15 to both sides</em>

4x = x + 45          <em>subract x from both sides</em>

3x = 45            <em>divide both sides by 3</em>

x = 15

The point-slope form of the equation of the line that passes through (-9,-2) and (1,3) is y-3=1/2(x-1) what is the slope-interce
Vikentia [17]

Answer:

y = (1/2)x + 2 1/2

Step-by-step explanation:

y - 3 = (1/2)(x - 1)

Distribute the 1/2

y - 3 = (1/2)x - 1/2

Add 3 to both sides

y = (1/2)x + 2 1/2
