Answer: 80
-----------------------------------------
Explanation:
x = number of defective drives in the shipment of 20,000 total
We are told that 2 defective drives are in the shipment of 500. So the first fraction to set up is 2/500
The second fraction is x/20000 as we divide in the same order as before (number of defective over the total)
Set those two fractions together to get this proportion
2/500 = x/20000
Now cross multiply
2/500 = x/20000
2*20000 = 500*x
40000 = 500*x
500x = 40000
The last step is to divide both sides by 500 to isolate x
500x = 40000
500x/500 = 40000/500
x = 80 which is the answer we want
Note: This is an expected/estimated amount and not entirely guaranteed to be reality. It's based on the previous ratio of 2/500, assuming the same ratio is held in check.
This is how you solve 1/2(8+6)-2=4+x-2

Answer:
Step-by-step explanation:
<u>Substitute x with -2 to find the value:</u>
- f(-2) = (-2)² - 3(-2) + 4 = 4 + 6 + 4 = 14
Answer:
You will need 3 cups peanut butter to make 36 dogs treats.
Peanut butter Cup : The dog treats made = 1: 12
Step-by-step explanation:
12 dog treats = 1 cup
So, by UNITARY METHOD
1 dog treat = (1/12) cup
So, 36 dog treats = 36 x (1/12) cup = 3 cups
So, you will need 3 cups peanut butter to make 36 dogs treats.
If 1 cup = 12 Dog Treats
then 1 x 3 cup = 12 x 3 dog treats
or, 3 Cups = 36 dog treats
The ratio of the Peanut butter cup : The dog treats made = 1: 12
