Step-by-step explanation:
150, 155, 160, 165, 170, 175, 180, 185, 190, 195, 200
There are 11 numbers when counting by 5.
150, 153, 156, 159, 162, 165, 168, 171, 174, 177, 180, 183, 186, 189, 192, 195, 198
There are 17 numbers when counting by 3.
Andrew/Sam = 11/17
$12/25 pencils= $0.48 per pencil
I don't if this is right but is the 629
x^2 = 2x + 15
x^2 -2x - 15 = 0
Factor:
(x-5)(x+3) = 0
x = 5 or x = -3
y=-2x+5. The slope (-2) of the equation is the same, so they are parallel.
4*6 -2*6 1*6 = 24 -12 6
7*6 3*6 0 42 18 0
