Seperate the number 53 into 3 parts so that the second number is 3 less than the first number and the third number is twice the first number. Give the value of the second number.

Answers

Answer 1

Answer: Hello,

Let a the first, b the second and c the third.
a+b+c=53
b=a/3
c=2a
==>a+a/3+2a=53
==>10a/3=53
==>a=15.9
c=2*a=2*15.9=31.8
b=a/3=15.9/3=5.3

Proof: a+b+c=15.9+5.3+31.8=53

The second number is 5.3

Theresa worked 9 hours on Monday and 7 hours on Wednesday. Her total pay was $116.00. What is her rate per hour?

Answers

GivenSituation: Theresa worked 9 hours on Monday and 7 hours on Wednesday.
=> First let’s add the total amount of hours Theresa rendered.
=> 9 + 7 = 16 hours in total
Her total pay was $116.00. What is her rate per hour?
=> Let’s solve for the unit rate:
=> 16 hours for 116 dollars.
Let’s find x dollars / hour
=> 116 dollars / 16 hours = 7.25 dollars / hour.
Thus, she is paid 7.25 dollars every hour she do her work

If you would like to know what is her rate per hour, you can calculate this using the following steps:

9 hours on Monday + 7 hours on Wednesday = 9 + 7 = 16 hours

$116.00 / 16 hours = 116.00 / 16 = $7.25

The correct result would be $7.25.
