Answer:
assuming that there are an equal number of colored marbles in the bag and their total is 20 marbles in the bag:
C) 17/20
Step-by-step explanation:
Set up the ratio as fractions
(5/8) cup red / (2/5) cup yellow = r amount of red / 1 cup yellow
Then cross multiply the numbers and set up as a equation like this
(5/8) × 1 = (2/5) × r
(5/8) = (2/5)r
Multiply both sides of the equation by (5/2) to get rid of the fraction and solve for r
(5/2) × (5/8) = (2/5)r × <span>(5/2)
25/16 = r
Reduce down to 5/4 or change to a mixed number
1 and 1/4 cups = r</span>
Answer:
If we solve this equation for y, it is equal to 18 - b
Step-by-step explanation:
To find this, we start with the original.
18 = y + b
Now we subtract b from both sides.
18 - b = y
