The answer would be 1/2 because the closest to 9/16 is 8/16 which can be simplified to 1/2
Answer:
An adult ticket is 17
A childs ticket costs 12 dollars
Step-by-step explanation:
Let a = adult price
c = child price
3a + 4c = 99
2a + 3c = 70
Multiply the first equation by 2
2(3a + 4c) = 99*2
6a + 8c = 198
Multiply the second equation by -3
-3 (2a + 3c) = 70*-3
-6a -9c = -210
Add these new equations together
6a + 8c = 198
-6a -9c = -210
----------------------
-c = -12
Multiply by -1
c = 12
A childs ticket costs 12 dollars
Now we need to find the price of an adult ticket
2a + 3c = 70
2a + 3(12) = 70
2a +36 = 70
Subtract 36 from each side
2a +36-36 =70-36
2a = 34
Divide by 2
2a/2 = 34/2
a = 17
An adult ticket is 17
Answer:
a+b = b+a
Step-by-step explanation:
Answer:
56.5 ft
Step-by-step explanation:
Here we know that:
- Keisha swims 18 feet from one side of her circular pool to the other swimming straight through the center --> this means that the diameter of the swimming pool is 18 feet, so
d = 18 ft
- Then, she swims one time around the entire edge of her swimming pool. --> this means that she swims along the perimeter of the swimming pool
The perimeter of a circle is given by
where d is the diameter. Therefore in this case, the length of Keisha's second swim is:
Answer:
16 feet
The length and the feet long are the same thing in this situation.
