No, it is an exponential equation. It has an exponent.
You don't find the ratio of one number.
You find the ratio of two numbers.
Their ratio is their quotient ... one number divided by the other one.
So there are three variables, rs2 label x, rs5 label y, rs10 label z
Lets write equeations using these variables.
x+y+z=120 (<span>A bag has a total of 120 notes)
2x+5y+10z=760 (total value)
2x+5*2y+10z=960 (twice as many rs5)
3 variables, 3 independent equations will give solution. There are a fair few ways to solve this. </span>
Answer:
(-1,-2)
Step-by-step explanation:
I graphed the equation on the graph below so you can see that (-1,-2) is a solution.
I think that she started with 10.. I'm not 100% sure, though
