The answer I got was 4 cans. I really hope my math was right!
Answer:
B, because of the signal word "took"! :)
Here is the graph that i found for this problem
Lets say you are trying to find the X in this equation:
2x-8=18 1. find a way to leave the 2x by itself.
2x=26 2. since the 8 is a negative (-8), becase it has a subtraction sighn , you add it to the 18 on the opposite side so yu have the 2x by itself.
3. Now you have to divide since there is nothing else you can do.
You divide 26 by two and then 2 by 2. now you have x=13.
This technique goes the same for if you have more that just two numbers that dont have a variable, but you said two step, so this is a prime example. I hope this helped. :)
Answer:
The annual income of A and B are in the ratio 3 : 4. If the income of A is 3x, the income of B is 4x. Their annual expenditure is in the ratio 5:7, if A's expenditure is 5y, B's expenditure is 7y. Each of them saves 15000 per month.
Step-by-step explanation:
=> 3x - 5y = 15000 and 4x - 7y = 15000
3x - 5y = 15000
=> y = (3x - 15000)/5
Substituting...
