the area in square feet is 4400. (because to find the area of the rectangle you multiply the 2 side lengths, 100 and 80 which gives you 8000, then you find the area of the square, multiply 60 by 60 which is 3600, then you subtract the total area of the backyard by the area taken up by the garden, 8000-3600, which gives you your total of 4400.)
All you have to do is plug in the value of X in each expression for the sides of the triangle. Then after you figure out the values for the sides of the triangle in feet. Add the sides together to find the perimeter of the triangle.
Answer:
Step-by-step explanation:
56 divided by 15 equals 3.5, so it's 3.5:1
32 + 2x = 84
2x = 52
x = 26
child's ticket is $26
Answer:
There are 8 adults in the group.
Step-by-step explanation:
Let the number of adults in the group be 'x'.
Given:
Number of children = 1
Number of adults = 'x'
Cost for a ticket of adult = $9
Cost for a ticket of a child = $6
Total cost = $78
Total cost is equal to total cost of tickets of 'x' adults plus cost of ticket of 1 child.
Unit cost of 1 adult × Number of adults + cost of ticket of 1 child = Total cost
Framing in equation form, we get:

<u><em>Adding -6 on both sides, we get:</em></u>

<u><em>Dividing both sides by 9, we get:</em></u>

Therefore, there are 8 adults in the group.
