Ten decreased by twice a number is the same as -28

Anzelm wants to burn 540 calories while jogging. Jogging burns about 12 calories per minute.

he usually plans to stop and rest for about 5 minutes.

m  represents the total minutes.

12 calories per minute.

for m minutes the calories burn is 12m

He stop and rest for about 5 minutes. so we need to subtract 5 from total minutes

So expression becomes 12(m-5)

He wants to burn 540 calories. So we set the calories = 540

The equation becomes ,

12(m-5) = 540

Now we solve for m , total number of minutes

12(m-5) = 540(divide by 12 on both sides)

m - 5 = 45

m = 50 ( add 5 on both sides)

Anzelm should plan to be out jogging for 50 minutes

So B is halfway between 0 and 1. What's half of 1? 1/2.

A is halfway between 0 and B. What's half of 1/2? 1/4.

So A is 1/4 of 1.

Alternatively -

0 - A - B - - - 1

If each - is an eighth, A is at 2/8, or 1/4

Answer:

So B is halfway between 0 and 1. What's half of 1? 1/2.

A is halfway between 0 and B. What's half of 1/2? 1/4.

So A is 1/4 of 1.

Alternatively -

0 - A - B - - - 1

If each - is an eighth, A is at 2/8, or 1/4
