This is a sum and difference problem,
larger number = (sum+difference)/2 = (6.1+1.6)/2 = 3.85
smaller number = (sum - difference)/2 = (6.1-1.6)/2 = 2.25

Answer:

3.85 and 2.25.

Step-by-step explanation:

Let x and y represent two numbers.

We have been given that sum of two number is 6.1. We can represent this information in an equation as:

x+y=6.1...(1)

We are also told that there difference is 1.6. We can represent this information in an equation as:

x-y=1.6...(2)

Upon adding both equations, we will get:

x+x+y-y=6.1+1.6

2x=7.7

\frac{2x}{2}=\frac{7.7}{2}

x=3.85

Upon substituting x=3.85 in equation (1), we will get:

3.85+y=6.1

3.85-3.85+y=6.1-3.85

y=2.25

Therefore, our required two numbers are 3.85 and 2.25.

MA_775_DIABLO [31]

Answer:

The maximum number of hours the repairman estimated for the job is 5.

Step-by-step explanation:

It's simple. First, all you have to do is start with the budget he gave you and subtract the fixed price.

225 - 35 - 40 = 150

Then, use the money you have left over (150) and divide by how much he pays per hour which equals 5.

150/30 = 5

Hope this helps! If you have any additional questions please don't hesitate to ask me or your teacher to be sure you master the subject. Stay safe and please mark brainliest!  :)
