Let
Y be the age of Franco's dad.
X Franco's age
Y = 3*X (1)
(Y +10) = 2*(X+10) +2 (2)
(3*X +10) = 2*X +20 +2
(3-2)X = 22 -10
X = 12 years old (Franco)
Y = 3*12 = 36 years old (Franco's dad)
Answer:
1.

represents the total number of people.
2.
where
represents the total number of people.
3.
where

4.
where
represents the total number of people.
Step-by-step explanation:
Question 1 explanation: Since no more than 10 people are allowed in the elevator, that means 10 and under are allowed, so the inequality would be
.
Question 2 explanation: Since the tour bus needs at least 8 people to sign up to run, that means 8 and more people will allow the tour bus to run, so the inequality would be 
Question 3 explanation: Since the most you will pay for a pair of jeans is $60, that means jeans costing $60 and under are fine, so the inequality would be
.
Question 4 explanation: Since over 20 people showed up to the party, that means there were more than 20 people at the party, so the inequality would be
.
1/((R2+R1)/(R2*R1))
= 1/(R2+R1) * (R2*R1)/1
So answer 4

Answer:
22 students
Step-by-step explanation:
First find a common denominator, which will be 48 here since it is more convieniant. Then multiply have all denominators equal 48, multiplying 6 by 8 and 8 by 6 to get 8/48 and 18/48. Then add them together and subtract them the 26 from 48 to get 22.
