Answer:
40
Step-by-step explanation:
According to the statement we have that both begin at the time.
Gear 1 = 4 turns
Gear 2 = 5 turns
They also do not say that they coincide at turn 20.
If we continue, we can calculate when they coincide again:
1st
20 + 4 = 24
20 + 5 = 25
2nd
24 + 4 = 28
25 + 5 = 30
3rd
28 + 4 = 32
30 + 5 = 35
4th
32 + 4 = 36
35 + 5 = 40
5th
36 + 4 = 40
They therefore coincide again at turn 40.
8:12 is 2/3 and so is 16:24, 2:3, and 20:30
Step-by-step explanation:
For example (includes simplified problem solving),
8 ÷ 4 = 2
12 ÷ 4 =3
You would want to divide the numerator and denominator by the greatest common factor (GCF)
The ratio 8:12 can be reduced to its lowest terms by dividing both terms by the GCF
Therefore 8:12 is 2:3
Answer: 11160 is your answer for this question
Step-by-step explanation:
3y - y + 8 - 2 = 20
3y - y = 2y
8 - 2 = 6
2y + 6 = 20
2y = 20 - 6
y = 10 - 3
the answer is: y = 7
