74 = 20(2.5) + 20(x)
74 = 50 + 20x
74-50 = 20x
24 = 20x
24/20 = x
1.2 = x
x = 1.2 yards of red felt
Answer:
P = 8.9k
Step-by-step explanation:
To find the perimeter, you need to add all three sides of the triangle.
P = (1.8k - 5) + (3.5 + 6.1k) + (k + 1.5)
Because you are adding all three expressions, you can remove the parentheses.
P = 1.8k - 5 + 3.5 + 6.1k + k + 1.5
Now you want to combine the variable (k).
P = (1.8k + 6.1k + k) - 5 + 3.5 + 1.5
P = (8.9k) - 5 + 3.5 + 1.5
Now you want to combine the constants.
P = (8.9k) - 0
You are left with:
P = 8.9k
