8th grade students held a fundraiser dinner. they paid a flat rate of $125 for the use of a building plus $13 for each student who attended. the total cost was $944. how many students attended?

63 students

Step-by-step explanation: Subtract $944-$125 = $819. After we get this answer we divide it by $13. $819 / $13= 63. Therefore, 63 students attended the dinner.

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.

320ft

step-by-step explanation:

120 divided by 3 equals 40

40 times 4=160

160 times 2=320
