Answer:
First, we have rounded numbers A and B, and we know that:
A + B = 11000
A - B = 3000
Now we can solve this system of equations as:
Isolating one variable in one of the equations, i will choose A in the second equation:
A = 3000 + B.
Now we can replace this into the other equation:
3000 + B + B = 11000
2*B = 11000 - 3000 = 8000
B = 8000/2 = 4000
and:
A - 4000 = 3000
A = 3000 + 4000 = 7000.
But remember that our original numbers are not exactly whole numbers, they are rounded up, so we could write them as:
A = 6999.8 (that would be rounded up to 7000)
B = 3999.7 (that would be rounded up to 4000)
The sum is:
A + B = 10999.5 (notice that this would be rounded up to 11000)
A - B = 3000.1 (this would be rounded down to 3000)
If not the answer that I got is 26/57 = [849 x(x= 372.25)]/5
Answer:
7/10 feet/year
Step-by-step explanation:
This straight line graph passes thru (0, 0) and (10, 7).
As x increases from 0 to 10, y increases from 0 to 7. Thus, the slope of this line, which is the unit rate, is m = rise / run = 7/10 feet/year.
