13/8 or 1 5/8
3/4 becomes 7/8 when add it is 13/8
Answer:
A) Sometimes
A ) Sometimes is the correct answer because b) always and c) never is not possible
it cannot be always measured 90 degrees
Using elimination, we add the equations, but this time from left to right. This process wants to elimination a variable. So 2x plus -2x equals 0. Moving on the next variable, 6y plus -y is 5y. On to the last variable, 18 plus 12 is 30. So we have this equation, 5y=30. 30/5 is 6, so y=6. We plug 6 into y in one of the equations you choose. In this case, I'm going to use the first equation. Plugging 6, we have this equation, 2x plus 36 is 18. 18-36 is -18. We then have this equation, 2x=-18. We know -9 times 2 is -18, so our x value is -9, So, our y=6, and our x=-9.
Answer:
(_1,_7),(_2,_6),(_3,_5),(_4,_4)(_5,_3)
2+1.25f=10-2.75f Add the variables
2+4f=10 isolate the variable
4f=8
f=2
