<em>An adult ticket costs $205 and a child ticket costs $49.</em>
<h2>
Explanation:</h2>
Hello! Recall you have to write complete questions in order to find exact answers. Here I'll assume the complete question as:
<em>Two families are planning a trip to Disney. The Smith family bought tickets for 2 adults and 3 children for $557. The Jones family bought tickets for 2 adults and 1 child </em><em>for $459</em><em>. How much does and adult and child ticket cost?</em>
To solve this problem, we need to write a system of linear equations in two variables. So, we know some facts:
- Two families are planning a trip to Disney.
- The Smith family bought tickets for 2 adults and 3 children for $557.
- The Jones family bought tickets for 2 adults and 1 child for $459.
Let:
For the Smith family:
Cost for the 2 adults:
Cost for the 3 children:
Total cost:
For the Jones family:
Cost for the 2 adults:
Cost for the 1 child:
Total cost:
So we have the following system of linear equations:
Subtracting (2) from (1):
Finally, <em>an adult ticket costs $205 and a child ticket costs $49.</em>

Answer:
That actually depends. We don't know if i is a negative number or not. If i is a negative number, -i would be larger. If i is a positive number, -i would be smaller. It all depends on whether i or -i is negative or positive.
Hope that helps!
Step-by-step explanation:
Answer:
x = 45
y = 15
Step-by-step explanation:
Given that:
x = pineapple smoothies
y = mango smoothies
According to given conditions:
x + y = 60.................... eq1
$2.75 x + $3.25y = $172.50 ............ eq2
By taking eq1
x + y = 60
x = 60 - y
Putting value of x in eq2
$2.75 (60 - y) + $3.25y = $172.50
By simplifying
$165 - $2.75y + $3.25y = $172.50
Adding like terms:
$0.5y = $172.50 - $165
$0.5y = $7.5
Dividing both sides by $0.5
y =7.5/0.5
y =15
Putting value of y in eq 1
x + 15 = 60
x = 60 -15
x = 45
So there are 45 pineapple smoothies and 15 mango smoothies.

Answer:
A: Fraction = 11/16 of an inch. Decimal = .6875 inch
B: Fraction = 2 1/2 inch. Decimal = 2.5 inch
Step-by-step explanation:
Each inch is divided by 16ths on the ruler. Count where the measured values lay on the ruler. Once you find the fraction you can divide the fraction to find the decimal answer.
