If m = 16 and n = 4, what is the value of the following expression?
m - 2 • n + 2
Answer:
10
Step-by-step explanation:
Use PEMDAS to rewrite the equation as:
m - (2 * n) + 2 =
16 - (2 * 4) + 2 =
16 - 8 + 2 =
10
Answer:
When m = 16 and n = 4, m - 2 * n + 2 = 10.
Step-by-step explanation:
m - 2 * n + 2
Substitute values given
m = 16
n = 4
16 - 2 * 4 + 2
Multiply -2 and 4.
16 - 8 + 2
Subtract 8 from 16.
8 + 2
Add 8 and 2.
10.
If the original expression had parenthesis, please let me know as this answer would need to be edited.

Nadia charges $6.50 an hour for babysitting. She babysits 19.50 hours the first week of the month and 19 hours the second week of the month.
Suppose Nadia raises her rate by $0.65 an hour. How many hours would she need to work to earn the same amount of money she made in the first two weeks of the month?
Complete the explanation and give your answer.
Nadia's new hourly rate is $___ .She would need to work ___ hours in the next two weeks to make the same amount she made in the first two weeks.
Answer:
Her new hourly rate is $7.15. She would need to work 35 hours in the next two weeks to make the same amount she made in the first two weeks
Step-by-step explanation:
6.50+.65=7.15 which is the new hourly rate
19+19.50 to find how many hours in total which is 38.5 hours
you multiply the rate of 6.50 by 38.5 and you get $250.25 in 2 weeks for the old rate.
I just multiplied until I found the amount of hours to make 250.25 with the new rate.
7.15x35=250.25
Answer:
New hourly rate: $7.15
Total number of hours: 35
Step-by-step explanation:
$6.50 per hour:Given Nadia's hourly rate of $6.50:
For the first week of the month, she babysits for 19.50 hours:
$6.50 per hour × 19.50 hours = $126.75 (Week 1)
For the second week of the month, she babysits for 19 hours:
$6.50 per hour × 19 hours = $123.50 (Week 2).
For those two weeks, she worked for a total of 38.50 hours, and earned $250.25.
$6.50 + $0.65 per hour increase:Nadia increased her hourly rate by $0.65, which means that her new hourly rate will be: $6.50 + $0.65 = $7.15 per hour.
Since we need to determine how many hours she needs to work for in the next two weeks to make the same amount as she did in the first two weeks, we could divide her weekly earnings by her new hourly rate for babysitting:
Week 3:Divide Nadia's earnings for week 1 by $7.15:
$126.75 ÷ $7.15 = 17.72 hours
Week 4:Divide Nadia's earnings for week 2 by $7.15:
$123.50 ÷ $7.15 = 17.27 hours
Week 3 + Week 4 hours = 17.72 + 17.27 = 34.99 or 35 hours
If you multiply her total working hours for weeks 3 and 4 by her new hourly rate:
35 hours × $7.15 per hour = $250.25 (This matches her total earnings for Week 1 and 2).
Therefore, Nadia's new hourly rate is $7.15. She would need to work for 35 hours in the next two weeks to make the same amount she made in the first two weeks.

A Ferris wheel accommodate 75 people in 30 minutes . how many people could ride the Ferris wheel in 6 hours? what was the rate per hour?
Answer: The ferris wheel could accomodate 900 people in 6 hours. The rate per hour was 150 people.
Step-by-step explanation:
To start off we can find the number of people by deciding how many time slots of 30 minutes are in 6 hours. Since 30 minutes is half an hour we just do 2 times 6 which would give us 12. Since 75 people can fit in 30 minutes then we do 12 times 75 for the whole 6 hours which comes out to 900.
Once we have the number of people in 6 hours then we can find the hourly rate. To do this we just take the number of people (900) in the whole time (6 hours) and divide 6 from 900 which would give us the hourly rate of 150.
Answer:
900 people
Step-by-step explanation:
One hour is 60 minutes, and the number of thirty minutes in an hour is two. To get the number of thirty minutes in 6 hours, you would do 2 x 6, which is 12. After this, you would do 12 x 75 since 75 people ride it in 30 minutes. This equals 900.

solve the equation
½ (6f – 4) = 3f - 2
Answer:
There is infinite solutions to f so it is an Identity
Step-by-step explanation:
Multiply (6f - 4) by 1/2 then you should get 3f - 2= 3f - 2
Add positive 2 in both sides then you should get 3f = 3f
Then multiply by its reciprocal and get f = f

An object that weighs 1 on Earth weighs 1.19 pounds on Neptune. Suppose a dog weighs 9 pounds on earth. How much would the same dog weigh on Neptune?
(40 points!)
Answer:
f 1 pound on Earth is equal to 1.19 pounds on Neptune all you have to do is multiply the number of Earth pounds by their Neptunian equivalent: 9x1.19=10.71 the dog would weigh 10.71 pounds :) I hope this makes sense :)
Answer:
They will weigh 10.71 on Neptune
Step-by-step explanation:
We can write a ratio to solve
1 Earth 9 Earth
-------------- = ---------------
1.19 Nept x Neptune
Using cross products
1x = 1.19 * 9
x =10.71
They will weigh 10.71 on Neptune
