You need to set up a portportation to solve this question to do so you need to know that 3 tenths is 30% so you can do:
30/100 = x/1.7
So now you cross multiply doing 30X17=510
Finially X=510/100
Simpified Answer is 5.1 liters
Hello!
We have the difference between 30 and x(our unknown value) is equal to 17; so we just simply set it up that way. Always think of x or any variable(like in your question they use p, it can be anything u want, it’s simply a representation of an unknown value we are trying to find)as your unknown and what operation they are implying as in this case it’s subtraction as they want the difference between 30 and x.
So the answer is a. 30-p=17
Hope this helped and any questions please just ask. Thank you!
646/3=x
To check it: x*3 should =646
The value of x would be: 5
