Answer:
25
Step-by-step explanation:
5 times 5
8(3) - 3y = 12
First, multiply 8 × 3 to get 24.
Second, subtract '24' from both sides.
Third, subtract '12 - 24' to get '-12'.
Fourth, divide both sides by '-3'.
Fifth, change the whole fraction to a negative.
Sixth, 12 ÷ 3 = 4. Simplify your fraction to 4.

Answer:
y = 4
There are 17 people. 3 Times 5 = 15 + 2 = 17
5+7+8=20 which is the total number of balls that the bag contains
because out of the 20 balls only the 8 are blue, it is right to say that
8/20 = x/100 ⇒ x= (8·100)/20 ⇒ x= 800/20 ⇒ x=40
the blue balls are the 40%
