Answer:
20
Step-by-step explanation:
Segment ST is half and RS is the other half. RT is the whole line so adding ST and RS will get you RT. 4x-7+3x-8=4x. solve for x which will get you 5. Replace the x with 5 in 4x (for segment RT) will get you an answer of 20 for the whole line.
The ratio In simplified form of those who both bike and run to those who do neither is 12: 1.
The missing data is attached in the image
<h3>What is Ratio ?</h3>
When two numbers are divided and written in the form p:q then they are called in Ratio.
It can be understood from the data given
The people who run and Bike is 42
The people who do neither is 3
The ratio of those who both bike and run to those who do neither is 42 :3
In simplified form 12: 1
Therefore the ratio In simplified form of those who both bike and run to those who do neither is 12: 1.

a. it would be 105° because the 75° and this angle make a linear pair which adds up to 180°.
b. this is 105° because the two angles are alternate interior which are congruent
c. this is 75°, it is given.
Y=x+12 is the parallel line that passes through this point
