Question

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)

Answer 1

Part C: Is it possible for Matilda to have spent 50 minutes practicing the electric guitar every day? Explain your reasoning. (2 points)

Answer 3

"Matilda practices guitar for a total of 70 minutes every day. She spends 10 minutes more practicing the electric guitar than the acoustic guitar."

Determine the amount of minutes for

acoustic

electric

Answer 4

so it should be E=40 A=30 Y=40E+30A?

Answer 5

No you would have two seperate equations

simply

y=40x

y=30x

Answer 6

OK

Answer 7

so what about part B?

Answer 8

is this Algebra 1? Because I did this like 2 days ago

Answer 9

yes an i think you mean x=40 y=30 cuz i just read it carefully lol

Answer 10

ok so let me go over from part A

Answer 11

ok

Answer 12

let y represent the electric guitar and x represent the acoustic guitar.

Answer 13

she plays the electric guitar 10 mins more than the acoustic

Answer 14

so i was right?

Answer 15

what were your equations?

Answer 16

ok i had x=30 y=40

Answer 17

ok

Answer 18

this is one of the equations I have
y + 10 = x

Answer 19

oh ok

Answer 20

and 70=x+(10+y)

Answer 21

now move on to part B

Answer 22

ok

Answer 23

do you know the answer

Answer 24

how many mins does she play the acoustic guitar

Answer 25

30 mins

Answer 26

brb ima go eat i'll tag you back real quick

Answer 27

ok then we'll work on part C

Answer 28

@Mehek14

Wouldn't the equations just simply be

y=30x
y=40x

they are just linear equations to demonstrate the minutes per day

Answer 29

@Mehek14 im back @dtan5457 i really dont think so because it says x for acoustic y electric

Answer 30

ok Part C

Answer 31

Ooh, I missed that

Answer 32

we have the equation 70 = (y + 10) + x

Answer 33

x = 30
y = 30 + 10

Answer 34

oh ok so i just plug it in?

Answer 35

if she plays 50 mins, the she has to play 40 mins of acoustic guitar since she plays the electric 10 mins more than the acoustic

Answer 36

so add 50 + 40

Answer 37

90 and i believe when you said x=30 and y=30 you meant y=40 because she'll be playing 50 minutes instead of 40

Answer 38

yes 90
90 does not equal to 70

Answer 39

so it isn't possible because she plays 70 mins every day

Answer 40

So that means she can't?

Answer 41

oh ok

Answer 42

there you go!

Answer 43

help with more?

Answer 44

3 more question left to go lol :3

Answer 45

i guess but i have to go soon

Answer 46

ok ill tag you again ok?

Answer 47

sure
