For #1 all you have to do is add them together. For #2 it is the same thing. For #3 all you need to do is use the less then (<) symbol with a 10 behind it. For #4 quotient means to divide so all you need to do is put a division symbol between the two factors. For #5 all you have to do is substitute 1.5 for the letter A and subtract them. For #6 all the do is substitute 2.25 for b because you convert the fraction to a decimal which is 25/100 which equals .25 then you divide the two numbers. For #7 the difference mean to subtract so you put x-6 instead of the difference between x and 6, then it equals 4.5 because you convert the fraction which would be 50/100 which equals .50. For #8 all you do is flip the word quotient the a division symbol because quotient means to divide.
