Answer:
step one simply hope it helped!
Step-by-step explanation:
The answer is D
Because if you replace the variables just by testing them they give the answer as X=-3 and Y=3.
In which replacing:
3(-3)+5(3)=6
and with the other equation we've got:
4(-3)+2(3)=-6
so they comply with the required to be the correct answer, even though you can make a system of equation.
The estimated price you will pay for lunch is $24.69.
Okay so you are going to really just add 30 + 9 here and that means you have 30 tens and 9 ones or a 30 in the tens place and a 9 in the ones place.
I hope i broke that down well enough.
I hope this helped :)
30/100 = 15/x
cross multiply
1500 = 30x
1500/30 = 50
