Step-by-step explanation:
Answer:
100 +3s≥ 160
You must sell as least 20 items
Step-by-step explanation:
You make 100 plus 3 dollars per sale
100 +3s
It must be at least 160
100 +3s≥ 160
Now we need to solve to see how many sales
100 +3s≥ 160
Subtract 100 from each side
100-100 +3s≥ 160-100
3s≥ 60
Divide each side by 3
3s/3≥60/3
s≥20
You must sell as least 20 items
(x²+4x-12)/(x-2)=0
(x+6)(x-2)/(x-2)=0
x+6=0
x=-6
(-6,0)
First, you have to convert 75/8 into a mixed fraction which will be 9 3/8. 9 3/8+ 5 3/4 = 15 1/8. Finally, you do 19 1/2 - 15 1/8 which is 4 3/8
The answer is 4 3/8
