tom is 20 years
Sam is 50 years
Step-by-step explanation:
- s+t= 70
- 4t=s
- putting value of s in step 2 from 1
- 4t=70-t
- 5t=70
- t=70/5
- t=20
- s=50
Answer: 45 = 5t
Step-by-step explanation:
From the question, Jamahl wants to celebrate his birthday by roller skating with his friends and he has a total of $45dollar to buy t tickets.
We are further told that the ticket costs $5. The equation that matches the situation will be:
45 = (5 × t)
45 = 5t
t = 45/5
t = 9
He can buy 9 tickets
Subtract 5 from the left side, then proceed to solve for x
1. True.
