Answer:
Imara's error will be that she did not find the side lengths of the square with an area of 625.
Step-by-step explanation:
Imara used these steps to find the length of the hypotenuse of the right triangle.
Step 1: Find the area of the square with side lengths of 20 i.e. 400
Step 2: Find the area of the square with side lengths of 15 i.e. 225
Step 3: Find the sum of the areas of the two squares i.e. 625
Step 4: State the length of the hypotenuse i.e. 625
Therefore, Imara's error will be that she did not find the side lengths of the square with an area of 625. (Answer)
First, we must let:
x = number of tickets intended for adults
y = number of tickets intended for children.
a. Write in terms of x the number of tickets for children
Solution:
x + y = 28 ⇔ y = 28 - x (equation 1)
To answer in terms of x:
no. of tickets for tickets for children = 28 - x
b. the amount spent on tickets for adults
Solution: $30 is the cost of ticket per adult and there are x number of tickets intended for adults.
Therefore,
amount spent on ticket for adults = 30x
c. the amount spent on the tickets.
Solution:
$ 15 = cost of ticket per child
$ 30 = cost of ticket per adult
total amount spent on tickets = 30x + 15y ⇒ (equation2)
substitute equation 1 to equation 2.
(equation 1) y = 28 - x
(equation 2) total amount spent on tickets = 30x + 15y
total amount spent on tickets = 30x + 15(28-x)
total amount spent on tickets = 30x + 420 - 15x
total amount spent on tickets = 15x + 420
Answer:
x = 2/9
Step-by-step explanation:
3x = 2/3
3*3x = 2
9x = 2
x = 2/9
Check:
3*2/9 = 2/3
6/9 = 2/3
