To answer this question, you need to understand how to change the description into an equation. Let say that Herbert's container volume is H and Betty's container is B. Then, from the problem you can get this equation:
1. B= 200 (Betty's container hold 200 milli liters)
2. H= 7/8 B (Herbert's container hold 7/8 as much juice)
If you put the 1st equation into the 2nd, you will get:
H=7/8 (200)= 175
Then the two containers will hold
H+B= 200 + 175= 375milli liters
Answer:
kyle must sell 7500$
Step-by-step explanation:
If you take the 2500$ he makes base salary and subtract from 4000$ you get 1500$ and if you multiply it by 1.80 you get the other needed 80% of the required sales.
Answer:
5. 
6. 
Step-by-step explanation:
5. 
6. 
7.2 because you just add the -4.8 to cancel out the -4.8 on the right side. and you get 7.2
Direct variations look like this (y = 3x_
Not direct variations (or inverse variations) look like this (y= 1/3x.) They are often in fraction form.
So, in your problem the direct variations are:
y= 3x
x = -1
-0.5x = y
y= 2.2x +7
y= 4
The non-direct variations are:
y = 2/7x
