13/5 or 2 3/5 by the way nice profile picture
6/5 because how do you convert a percentage to a decimal? First you move the decimal points over by two, so you start off with 120 and end with 1.20. There are many ways you can go from here. If you have a graphing calculator like i do, then you type in 1.20 hit the "math" button, hit enter and a fraction already in its simplest form is given. I hope this helps, have a great day.
We have to use the functions:
h ( x ) = 2 x + 5 and t ( x ) = 7 x - 6
Part A:
( h + t ) ( x ) = ( 2 x + 5 ) + ( 7 x - 6 ) = 9 x - 1
Part B :
( h · t ) ( x ) = ( 2 x + 5 ) · ( 7 x - 6 ) = 14 x² - 12 x + 35 x - 30 =
= 14 x² + 23 x - 30
Part C :
h [ t ( x ) ] = h ( 7 x - 6 ) = 2 · ( 7 x - 6 ) + 5 = 14 x - 12 + 5 =
= 14 x - 7
