The answer is J
The rides she wants to ride cost 4+6+3 tickets so that goes on one side. She already has 7 tickets so you need to know 7 plus what will get her on those rides so those go on the other side. So you have:
7+t=4+6+3
Then you solve for t
7+t=13
t=13-7=6
Hope that helps.
C.) is the answer, I think
Answer:
Step-by-step explanation:
function 2
Answer:
Douglas can race the go-karts at least 3 times.
Step-by-step explanation:
Given that:
Worth of game card = $20
Cost of go-kart = $3.50 each time
Amount Douglas wants to left = $7.75
Let,
x be the times Douglas can ride go-kart.
20 - 3.50x ≤ 7.75
-3.50x ≤ 7.75 - 20
-3.50x ≤ -12.25
3.50x ≤ 12.25
Dividing both sides by 3.50

Hence,
Douglas can race the go-karts at least 3 times.
