Answer:
<u>Aaron played 4 games and went on 2 rides at the carnival.</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Cost of each game = US$ 2.75
Cost of each ride = US$ 4.75
Total spent by Aaron at the carnival = US$ 20.50
Number of rides = x
Number of games = 2x (the number of games he played is twice the number of rides he went on)
2. Determine the number of games Aaron played and the number of rides Aaron went on.
For determine the number of games and the number of rides, we will use the following equation:
2.75 (2x) + 4.75x = 20.50
5.5x + 4.75x = 20.50
10.25x = 20.50
x = 20.50/10.25
x = 2 ⇒ 2x = 4
<u>Aaron played 4 games and went on 2 rides at the carnival.</u>
So,
All you have to do is to translate the words into open sentences with placeholders.
Apparently, there are 2 numbers, call them x and y.
Now, build open sentences.
x + y = 12
x - y = 4
Now, which method will we use to solve? I choose Elimination by Addition.
Add the equations together.
2x = 16
Divide both sides by 2
x = 8
Substitute
8 + y = 12
Subtract 8 from both sides.
y = 4
Check
The sum of the two numbers is 12 (8 + 4).
The difference of the two numbers is 4 (8 - 4).
The first number is 8.
The second number is 4.
Answer:
19 yards
Step-by-step explanation:
75 - 50 = 25
15 * 19 = 285
285 + 25 = 310
