Matilda practices guitar for a total of 70 minutes every day. She spends 10 minutes more practicing the electric guitar than the acoustic guitar.

Part A: Write a pair of linear equations to show the relationship between the number of minutes Matilda practices the acoustic guitar every day (x) and the number of minutes she practices the electric guitar every day (y). (5 points)

Part B: How much time does Matilda spend on practicing the acoustic guitar every day? (3 points)

Part C: Is it possible for Matilda to have spent 50 minutes practicing the electric guitar every day? Explain your reasoning. (2 points)

Oh okay I get it now
70=x+y
and 
y=x+10 
those are your equations

anonymous · Answer

Because they both add to 70 and the electric is practiced 10 minutes more than acoustic

anonymous · Answer

Can you solve that system of equations? that is how you answer the next part

Thanks! And i think she spends 30 minuites practicing acoustic and 40 on the electric looking at it because if it was any more or any less it wouldnt be 10 minuites more
