I think there would be 24 combinations.
Area =lw
=2x (8+1)
=2x (9)
=18x
therefore the area is 18x
33.3 repeating percent
You set up a proportion
6/18 = x/100
100x6= 600
600÷18 = 33.3 repeating
Answer:
add 2x to both sides
Step-by-step explanation:
-x+2y=-10
2y=x-10
y=1/2x-5
Slope = -4/5
to calculate the slope m use the gradient form
m = y2 -y1
————
x2 - x1
let (x1, y1) = (3,1) and (x2, y2) = (-2, 5)
m = 5 - 1 4
———- = ——-
-2 - 3 -5
= - 4/5
