Answer:

4.8 megabytes / minute.

Step-by-step explanation:

At the beginning of recording the download you have 24 megabytes.

15 minutes later, you have 96 megabytes.

In 15 minutes you have downloaded 96 - 24 = 72 megabytes

So the question turns out to be  a proportion of

x megabytes / 1 minute = 72 megabytes / 15 minutes.

x = 72/15

x = 4.8 megabytes / minute

Solve<br><br> 3x + 8 = 2x + 21
Elanso [62]

Answer:

Step-by-step explanation:Simplifying

3x + 8 = 2x + -21

Reorder the terms:

8 + 3x = 2x + -21

Reorder the terms:

8 + 3x = -21 + 2x

Solving

8 + 3x = -21 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

8 + 3x + -2x = -21 + 2x + -2x

Combine like terms: 3x + -2x = 1x

8 + 1x = -21 + 2x + -2x

Combine like terms: 2x + -2x = 0

8 + 1x = -21 + 0

8 + 1x = -21

Add '-8' to each side of the equation.

8 + -8 + 1x = -21 + -8

Combine like terms: 8 + -8 = 0

0 + 1x = -21 + -8

1x = -21 + -8

Combine like terms: -21 + -8 = -29

1x = -29

Divide each side by '1'.

x = -29

Simplifying

x = -29

Apollo Spas services 105 hot tubs. If each hot tub needs 165 mL of muriatic acid, how many liters of acid are needed for all of
Licemer1 [7]

Answer:

17.325 liters

Step-by-step explanation:

Number of Apollo Spas Services= 105 hot tubs

Each hot tub needs Muriatic acid= 165 ml

We have to find the total liters of muriatic  acid

Total number of liters required = Number of hots cups× 165 ml

Total number of liters required= 105×165 ml

Total number of liters required= 17,325 ml

1ml = 1/1000 liters

Total number of liters required= 17.325 liters

Hence, the correct answer is 17.325 liters

36 students signed up to volunteer for a race two or three equal groups of students and each group had a different task how many
Delvig [45]

Answer:

I two groups are formed: 18 students

If 3 groups are formed: 12 students

Step-by-step explanation:

We will answer this problem based on two occurrences:

<em>1. The students chose to form only two groups:</em>

If the students chose to form only two groups, the number of students in each group will be got by dividing the total number of students by 2. this will be 36/2 = 18. Therefore, there will be 18 students per group if only 2 groups were formed.

<em>2. The students chose to form three groups:</em>

If the students chose to form three groups, we will divide the total number of students by 3. this will be 36/3 = 12. Therefore, there will be 12 students per group if only 3 groups were formed.
