A concert promoter sold 475 tickets to a rock concert. The ticket prices for different seat locations were $10, $15, and $20. The total income from the concert was $6,300. If the combined number of $10 and $15 tickets sold was 4 times the number of $20 tickets sold, how many $10 tickets were sold?

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

irrational, cannot

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

slope= 1

y-inter slope= 0

x       y

o     0

1       1

2     2

ect.
