Colton wants to ride his bicycle 53.2 miles this week. He has already ridden 10 miles.
If he rides for 6 more days, what is the average number of miles he would have to ride
each day to meet his goal?

Answers

Answer:

About 7 miles a day?

Step-by-step explanation:

53.2-10= 43.2

43.2 divided by 6 is  about 7.6. I’m just in middle school though :)

Colton will have to ride 7.2 miles per day on other to hit his target.

Total miles to ride = 53.2

Miles ridden already = 10 miles

Number of miles left to ride = (53.2 - 10) = 43.2 miles

Number of days left to ride = 6 days

The average ride per day will be:

Number of miles left ÷ number of days (43.2 ÷ 6) = 7.2 miles

Hence, Colton will have to ride 7.2 miles each day.

• Mrs. Alvarez rents skis and poles for 3 days.
What is the total cost of the rental?
• The total cost of the rental is $
​

Answers

The value that Mrs. Alvarez will pay depends on the rental value of the ski and the poles per day, for example $144.

How to calculate the total loan cost of Ski equipment?

To know the total cost of the loan of the Ski equipment, we must know the loan price per day or per hour.

For example, suppose the loan price per hour is $2, then we would have to calculate how much one day is equivalent to and then multiply it by the total number of days.

$2 x 24 = $48

$48 x 3 = $144

Note: This question is incomplete because some information is missing. However I can answer it based on my general prior knowledge.

What value of x makes the equation below true? −2x=−36 A x=−34 B x=−38 C x=−18 D x=18

Answers

Answer:

D x = 18

Step-by-step explanation:

Given equation:

−2x = −36

Divide both sides by -2 to find x

−2x / -2 = −36 / -2

x = −36 / -2

x = 18

x = 18 makes the equation −2x = −36 true
