I’m assuming there is a picture you are missing.
Answer: -204
Step-by-step explanation: 12 X -17 +Y is the same thing but you can say it this way and its easier to understand but it equals -204/(negative 204) Hope this helps you! :3
Answer: the lengths are 20 feet, 23 feet and 37 feet
Step-by-step explanation:
Let x represent the length of the shorter side of the triangular deck.
The second side of a triangular deck is 3 feet longer than the shortest side. This means that the length of the second side is (x + 3) feet.
The third side is 3 feet shorter than twice the length of the shortest side. This means that the length of the third of the triangle is (2x - 3) feet.
If the perimeter of the deck is 80 feet, it means that
x + x + 3 + 2x - 3 = 80
4x = 80
x = 80/4
x = 20
The length of the second side is
20 + 3 = 23 feet
The length of the third side is
20 × 2 - 3 = 40 - 3 = 37 feet
Answer:
The unit rate is 
Step-by-step explanation:
Let
x ----> the number of feet
y ----> represent the cost of a piece of pipe
we have
Remember that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
or 
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem we have a proportional relationship
The unit rate is the same that the slope of the linear function or the constant of proportionality k
so
therefore
The unit rate is
