To make things easier, pretend she has 100 marbles and halve everything except for the percentages (everything will be doubled later).
If 22% of her marbles are navy, then 22 marbles are navy.
If 40 (half of 80) her marbles are royal blue, then 40% of her marbles are royal blue.
If 38% are baby blue, she has 38 baby blue marbles.
How many cobalt blue marbles does she have? Well, 22+40+38=100
Since we added the percentages, the ratio would be the same whether she has 100 or 200 marbles.
Since the percentages of navy, royal blue, and baby blue added up to 100%, she has no cobalt blue marbles.
Place a point at (0,-5) because that is the y-intercept (the -5 on the vertical line)
Since the slope is negative two which can be re-written as -2/1 (rise/run) you go down two and to the right once or up two and to the left once, it doesn't matter which. Another point can be placed at (1,-7) or (-3,-1), it still doesn't matter which.
Then you can draw a line connecting the two points.
I hope this helps :)

Answer:
-8x+20
Step-by-step explanation:
multiply using the distributive property:)
Trey will read 18 pages in 45 minutes.
This is because he read 2.5 pages a minute. 25/10 = 2.5
so if we 45/2.5 = 18
