A car travels 83 7/10 miles on 2 1/4 gallons of fuel which is the best estimate of miles the car travels on one gallon of fuel
jeka94
To solve this problem we can use proportion, but first its nice to transform our fraction into improper fraction, so
83 \frac{7}{10}= \frac{837}{10}
and 
2 \frac{1}{4}= \frac{9}{4}
Now we can make proportion

\frac{837}{10}--------------------------\frac{9}{4} of fuel
x-----------------------------1
Now we can cross multiply

x= \frac{ \frac{837}{10} }{ \frac{9}{4} }= \frac{837}{10}* \frac{4}{9} =  \frac{3348}{90}=37.2 - its the result

Letters a, b, c, and d are angles measures.
seropon [69]
The answers are:

a = c

c = d

b + d =180 degrees

Here's how:

When a line intersects two parallel lines, then corresponding angles are formed which means the same corners are congruent.

option c = d is considered.

And, because of vertical angles,

a = d is also an answer.

Below is an attached picture of the figure
