The complete exercise is: "Which arrangement shows , 3.7, , and 3.89 in order from least to greatest?"</h3><h3>
</h3>
Convert from mixed numbers to decimal numbers.
The steps to do this, are the following:
1. You must divide the numerator of the fraction by the denominator.
2. Then you must add the quotient obtained to the whole number part.
Applying this procedure, you get that:
Now that you have all the numbers in decimal form, you can order from least to greatest:
Therefore, you can conclude that the correct arrangement is:
Answer:
Adult ticket: $7
Child ticket: $2
Step-by-step explanation:
Set up a system of equations where a represents the cost of one adult ticket and c is the cost of one child ticket:
2a + 3c = 20
a + 4c = 15
Solve by elimination by multiplying the bottom equation by -2:
2a + 3c = 20
-2a -8c = -30
Add them together:
-5c = -10
c = 2
Now, we can plug in 2 as c to find the value of a:
2a + 3c = 20
2a + 3(2) = 20
2a + 6 = 20
2a = 14
a = 7
