18 red marbles because add the ratio togather which is 5 and divide 90 by 5=18 for 1
Answer:
3y/ 7
Where y = the total number of athletes
Step-by-step explanation:
Let the total number of athletes = y
Let the number of all baseball athletes = b
Let the number of all basketball athletes = k
Let the number of all football athletes = f
The ratio b: k : f is given by:
15 : 12 : 8
Total proportion = 15 + 12 + 8
= 35
The ratio of all baseball player = 15/ 35
= 3/7
Number of baseball player = 3/7 of y
= 3y/7
The means the three- seventh ( close to half) of the total athletes play baseball ball.
The equation would look like this: 2.00 + 0.15x = 2.75
<u> - 2.00 - 2.00
</u> 0.15x = 0.75
<u /> <u>÷ 0.15 ÷ 0.15
</u><u /> x = 5 days
