For this case, the first thing we must do is define variables:
x: unknown number (1)
y: unknown number (2)
We now write the equations that model the problem:
their sum is 6.1:

their difference is 1.6:

Solving the system we have:
We add both equations:

Then, we look for the value of y using any of the equations:
Answer:
The numbers are:
Answer:
five times a number plus two
Step-by-step explanation:
Well not sure what you are asking, but If it is what I think it is, it would go like this:
2
(9^2)
Then the answer should be
9^4 since we multiply the exponents.
If you mean this...
3^2....It would be same as 3 x 3 which we should know is equal to nine.
Hope I helped! (Be sure to thank me!)
First, find out how much he made in the week total: 24($8.75) = $210
The, find 1.45% of 210: (.0145)(210) = 3.045
*note that 1.45% = .0145*
Round that number to 3.05 and you have your answer
