zac and lynn are each traveling on a tri so far ac has traveled 123.75 miles in 2.25 hours. Lynn leaves half an hour after Zar=c so far she has traveled 105 milwa in 1.75 hours assume Zac an Lynn travel at a constant rate

i think the length is 12 and the width is 17

he earned 78.75 in interest.

step-by-step explanation:

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.
