Answer:
B
Step-by-step explanation:
One crew is doing 1.3 miles daily, the other is doing 1.4 miles daily, so both together are doing 1.3 + 1.4 miles daily, namely 2.7 miles.
now, they are 6.75 miles apart, how many days will it be at a rate of 2.7 miles per day, that 6.75 miles will be done?

days
A relation is a set of inputs and outputs, often written as ordered pairs (input, output). We can also represent a relation as a mapping diagram or a graph. For example, the relation can be represented as:
Answer:
y=2x+2
Step-by-step explanation:
Remember that parallel lines have equal slopes. We can solve this using point slope form which is 
Plug in the point (0,2) into the equation:
y-2=m(x-0)
Also plug in the slope which is the same as line EF (m=2)
y-2=2(x-0)
Simplify:
y-2=2x
Add 2 to both sides:
y=2x+2
3.225
to check just find 10% of 21.50 (2.15) and 5% of 21.50(1.075)
