Answer:
3 1/4 + 2x ≥ 6
Step-by-step explanation:
Let X equal the remaining time she needs to practice.
You would have 2x
The combined total needs to be 6 hours or greater.
You need to add the amount she already practiced to 2x.
Now you have: three and one fourth + 2x
This needs to be greater than or equal to 6.
I hope this helps you :)
Answer:
The price of the admission is 15.
Step-by-step explanation:
From the information given, you can write the following equations:
a+3e=45 (1)
a+5e=65 (2), where:
a is the admission cost
e is the exhibition cost
First, you can solve for a in (1):
a=45-3e (3)
Second, you can replace (3) in (2):
45-3e+5e=65
45+2e=65
2e=65-45
2e=20
e=20/2
e=10
Finally, you can replace the value of e in (3):
a=45-3e
a=45-3(10)
a=45-30
a=15
According to this, the price of the admission is 15.
