Answer:
2.8+.55x=5 x=4
Step-by-step explanation:
5-2.8=2.2
2.2/.55=4
-3(1+6x) = 14 - x
-3 -18x = 14 -x
-18x +x = 14 + 3
-17x = 17
x = -17/17
x = -1
Therefore x is equal to -1.
Answer:
2
Step-by-step explanation:
The domain values uniquely map to the dependent variable.
A function that fits these values is f(x)=20x+1020.
If you take 3 inches off each end, that means you will be taking 6 inches off. If you take 6 inches away from 7 1/4 yards ,(7 yards, 9 inches,) you get 7 1/12 yards (7 yards, 3 inches).
(7 1/12) / 5 = 1.426repeating
So each piece of rope will be (Approximately) 1.4 or 1 2/5 yards.
