Step-by-step explanation:
a)
8÷2=4
12÷3=4
27÷9=3
•it does'nt always take the same amount of time to serve each customer .
•10×3=30
b)
according to the question
2=18 point
4=36 point
8=72 point
18=9×2
36=9×4
72=9×8
so 1dollar =9point
•each dollar spent appears to earn the same number of point
•because 81=9×9, it costs 9 dollar
Answer:
12.5 miles per hour.
Step-by-step explanation:
There are 60 minutes in 1 hour so:
12 minutes = 12/60 = 1/5 of an hour.
So his speed in mph
= distance in miles / time in hours
= 2.5 / 1/5
= 2.5 * 5
= 12.5 miles per hour.
The inequality passing through (1, 4), (-2, -2), intersecting the y-axis at 2 units and intersects the x-axis at (-1, 0) to form shaded portions on the left side is y > 2x+2

Hello,
Quadrant 1,Quadrant 2,Quadrant 3, Qaudrant 4
Hope this helps
Xy = k
(-4/15)(-105) = k
28 = k
xy = 28
10y = 28
Divide both sides by 10
y = 2.8
