Answer:
The last one is correct.
Step by step:
Each income has ONLY one outcome.
10 - 6x = 160 - 10x
+6x +6x
-10 + 6 = -4
10 = 160 - 4x
-160
10 - 160 = -150
-4x = -150
-4x/4 = -150/-4
x= 37.5

Answer:
2√13
Step-by-step explanation:
The distance formula is useful for this. One end of the vector is (0, 0), so the measure of its length is ...
d = √((x2 -x1)² +(y2 -y1)²) = √((6 -0)² +(-4-0)²)
= √(36 +16) = √52 = √(4·13)
d = 2√13 = |(6, -4)|
Steps:
1. Do 79.75 minus 14.85 which is 64.9
2. 64.9 is how much the discount was
3. You do a proportion
X/100 times 64.9/79.75
4. 64.9 times 100= 6,490
5. 6,490 divided by 79.75 is 81.379
Your answer is
81.379%
