Step-by-step explanation:
Each person's donation ratio is:
Donation 1 is 4/15 of 75
Donation 2 is 4/15 of 75
Donation 3 is 7/15 of 75
4/15(75) = 5 * 4 = 20
7/15(75) = 5 * 7 = 35
Each person's donation amount is:
$20
$35
Check out work:
20 + 20 + 35 = 75!
Answer C
steps
deduct 10 from 26
26-10 which will give us 16
Answer:
(3/4)^4 = 81/256
1 ÷ 81/256 = 256/81
So;
Zero solutions.
4x - 8 - 4x = 9
-8 = 9
No solutions.
