Answer:
B. 7/2 miles per 1 hour
Step-by-step explanation:
The unit rate in this case ,means ,
the number of miles for every 1 hour
Since Taylor walks 7 miles in 2 hours
Then
He walks 7/2 miles in 1 hour
Thus
The unit rate that Taylor walks at is :
7/2 miles per 1 hour
Check the picture below.
so, notice, the composite is just a 4x6 rectangle, and a triangle whose base is 6 and altitude is 2. So, we can simply get the area of each figure and sum them up.
angle LMN and L are corresponding so they are equal to each other
x = 3x - 70
...subtract 3x
-2x = -70
...divide by -2
x = 35
...angle LMN: 3(35) - 70 = 35
answer is C
M=3n
divide both sides by 3
M/3=3n/3
on the left hand side, the numerator constant cuts the denominator 3
therefore, n=M/3
