Answer:
3 3/8
Step-by-step explanation:
1 3/4 + 1 5/8
We need to get a common denominator of 8
1 3/4 *2/2 + 1 5/8
1 6/8 + 1 5/8
I like to line them up vertically
1 6/8
1 5/8
---------------
2 11/8
But 11 is larger than 8 so we subtract 8/8 and add 1
2 11/8
+1 -8/8

3 3/8
<span>SALES: 5x² + 2x – 80
</span>- COST: 5x² – x + 100
= ------------------
PROFIT: 0x²+3x-180
(+3x because we subtracted a negative (-x), which is called adding, similarly taking away 100 from negative 80 is -180.)
Checking:
5x² + 2x – 80
5(500)²+2(500)-80 = 1,250,920
5x² – x + 100
5(500)² – (500) + 100= 1,249,600
Profit = 1,250,920 - 1,249,600 = 1,320
0(500)²+3(500)-180 = 1,320 YAY! {:-)
Double Checking:
5x² + 2x – 80
5(5000)²+2(5000)-80 = 125,009,920
5x² – x + 100
5(5000)² – (5000) + 100= 124,995,100
Profit = 125,009,920 - 124,995,100 = 14,820
0(5000)²+3(5000)-180 = <span>14,820</span> YAY! {:-)
