Mrs. Lee is setting up chairs for a band concert. The front row will have ten chairs. Thereafter, each row will have four more chairs than the row in front of it. Mrs. Lee knows that there will be five rows. How many chairs will she need?

Sorry this is to hard to do :) and imma say what you said IDC :)

Step-by-step explanation:

Nut sacks its what you said to me

Step-by-step explanation:

three-fourths of an hour

36÷48=0.75

0.75=

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.
