Charles finished 7 laps around the track. This is 20% of the number of laps he has to do. How many laps must he do?

andrew-mc [135]

To solve this problem, you have to use a proportion:
7/20 = x/100

After setting up the proportion, you have to cross multiply:
20x=700

Now, solve the equation by dividing by 20 on both sides:

x=35

So Charles has 35 laps left.

Joe drives 20 mi-in 1/2 h. how Long Will it take him to derive 50 mi?

tiny-mole [99]

An hour and 15 minutes. Since Joe is driving 20 miles per 1/2 hour that means he is driving 40 miles every hour. We still have 10 miles left and since 20 divided by 2 is ten you would simply cut the time it takes him to drive 20 miles in half making 15 minutes. Then you add the time it takes to drive 40 miles and 10 miles and that's how you get an hour and 15 minutes. Hope this made sense!

A teacher writes an inequality x divided by 6 < -2 on the board. Vincent incorrectly solves the inequality and obtains x <

scZoUnD [109]

The error Vincent made was that he only multiplied the left side of the inequality with 6 although he had to multiply on both sides

Step-by-step explanation:

Given inequality that the teacher wrote is:

$\frac{x}{6} -2$

Solving an inequality means that the variable should be isolated on left side of the inequality.

So multiplying both sides by 6

$6* \frac{2}{6} < -2 * 6\\x < -12$

Vincent got the answer is x<-2 = > The error Vincent made was that he only multiplied the left side of the inequality with 6 although he had to multiply on both sides
