Answer:
what are the answer choices?
Step-by-step explanation:
To isolate the variable multiply both sides by 5.
-3 = x/5
-3*5 = x/5 * 5
-15 = x
We can assign variables to each side:
x = first side
y = second side
z = third side
We will assume the "one side" that is greater than the second side is the first side. Since it is "2 times the second side" we can write this as:
x = 2y
Since the third side is 5ft longer than the second side, we can write this as:
y + 5 = z
Perimeter of the triangle (49ft):
x + y + z = 49
We can substitute everything we know.
(2y) + y + (y + 5) = 49
4y + 5 = 49
4y = 44
y = 11
Now we can solve for the other sides with what we have for y.
x = 2(11)
x = 22
11 + 5 = z
16 = z
Add to check.
22 + 11 + 16
33 + 16
49
Therefore, the side lengths are [ 22, 11, and 16 ]
Best of Luck!
