Brandon made $38.00 in 3 hours. How much would he make in 10 hours
Bad White [126]

Answer:

He would make $126.70 in 10 hours.

Step-by-step explanation:

First, you have to find the unit rate, in other words, how much money he earns in one hour. To do that, you have to divide.

38.00÷3= 12.666667

Once you know how much money Brandon earns in one hour($12.67), you multiply that number by 10.

12.67×10= 126.70

In conclusion, the answer to this solution($126.70) is how much money he earns in 10 hours.

1..) 2x +15 = 35 
Masja [62]

Answer:

1) x=10

2) x=3

Step-by-step explanation:

1)

2x+15=35

Subtract 15 from both sides

2x=20

Divide both sides by 2

x=10

2(10)+15=35

20+15=35

35=35

this shows that 10 is the right answer

2)

7x-3=18

Add 3 to both sides

7x=21

Divide both sides by 7

x=3

7(3)-3=18

21-3=18

18=18

this shows that 3 is the right answer

Hope this helps

How many people swam fewer than 30 laps?
Bas_tet [7]

Answer:

3 people

Step-by-step explanation:

Reading a stem & leaf plot can be hard!

Remember in the middle or whichever side is single digits divided by the line is your tens place values.

The 2 has two values on the other side, giving us 23 & 29 laps.

The 1 has one value on the other side, giving us 11 laps.

The 0 has no other value, so there is no data for that row.

There were 3 data points below 30, & these were 11, 23, & 29.

Hope this helped. :)
