A construction crew built 1/3 miles of road in 1/6 days

What is the unit rate in miles per day?

Write your answer in the simplest form.

2 miles per day

Step-by-step explanation:

The length of the road built is 1/3 miles, so let's call L = 1/3

The time spent to build this length is 1/6 days, so let's call D = 1/6

To find the unit rate in miles per day, that is, the speed that this length of the road was built, we just need to divide L by D (speed is distance over time). Let's call the speed S:

S = D/T

S = (1/3) / (1/6)

S = (1/3) * 6

S = 2 miles per day

mean, 40.6

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
