If liam arranges chairs in 9 rows of the same length he has 3 chairs left over if he arranges the chairs in 7 rows of that same length he has 19 left how many chairs does he have

75 chairs

Step-by-step explanation:

let x=number of chairs per row

let y=total number of chairs

use linear function:

y=9x+3

y=7x+19

9x+3=7x+19

9x-7x=19-3

2x=16

x=8

plug 8 into either equation

9×8+3=75

7×8+19=75

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
