Answer:
Step-by-step explanation:
Much depends on how accurate an estimate you want.
If "to the nearest hundred" would be acceptable (it's a lot of work),
Round off 542817 to 542820 and 27398 to 2740. Then you'd want to subtract 2740 from 542820. (Again, it's a lot of work.)
Otherwise round off to the nearest thousand: 543000 - 27000.
Or go to the nearest ten thousand: 540,000 - 30,000 = 510,000 (estimate)
Yes, so the answer would be C. You can use rise/run for this:
9/12=3/4
By simplifying 9/12, you get 3/4. Since 3/4=3/4, the hypotenuses can lie on the same line.

Answer:
A (-5,2)
Step-by-step explanation:
5x+y=-23
7x-3y=-41
3×(5x+y)=3×(-23)
15x+3y=-69
<u>+</u><u>7x-3y</u><u>=</u><u>-41</u>
<u>22x</u>=<u>-110</u>
22. 22
x=-5
5x+y=-23
5(-5)+y=-23
-25+y=-23
<u>+25</u><u>.</u> <u>+25</u>
y=2
When using elimination you add both equations together so that one variable cancels out the other. In this situation, y can be the variable. You must get the y-variables to cancel out leaving just the x- variables to solve for.
