Paul and Quinn share some money in a ratio 3:2, Paul gets 60 more than Quinn, how much does Quinn get
wlad13 [49]

Answer: 120

Step-by-step explanation:

3+2=5

Let x be the amount of money to be shared

Paul’s share which is (3/5)x is 60+ Quinn’s share which is (2/5)x

Therefore

(3/5)x= (2/5)x + 60

(3/5)x - (2/5)x= 60

(x/5)=60

Cross multiply

x= 60*5=300

It means that Quinn’s share is (2/5)(300)= 120

Genrish500 [490]

Answer:

10 SENIORS

Step-by-step explanation:

x=# of seniors

y=# of juniors

x+y=23, x=2y-7

  1. plug the value of x in the second equation into the first
  2. (2y-7)+y=23
  3. Remove parentheses
  4. 2y-7+y=23
  5. Combine like terms
  6. 3y-7=23
  7. Add 7 to BOTH sides
  8. 3y=30
  9. divide BOTH sides by 3
  10. 3y/3=30/3
  11. y=10
  12. There are 10 juniors in the class
  1. FINAL STEPS
  2. Plug y (which is 10) into the first equation
  3. x+y=23
  4. x+10=23
  5. subtract 10 from BOTH sides
  6. x=13
  7. Since X equals the number of seniors, there are 10 seniors in the class
