Try the divisibility rules: A number is divisible by 2 if the last digit is even. (a) ..1 NO (b) ..3 NO A number is divisible by 3 if the sum of the digits is divisible by three. (a) 2+3+1=6/3=2 with no remainder (b) 3+9+3=12/3=4 with no remainder Can you make the conclusions?

We have a bunch of right triangles here BCA=39, so CAD = 51 BEA=90, so EHA = 39 vertical angle DHB is thus 39 HDB = 90, so HBD = 51 Now we know all the angles A = 51+x B = 51+2x so, 39+51+x+51+2x = 180 x = 13 ABC = 26

there many way to do this i liek to change it all to improper fraction first 2 3/18= 39/18 ; 5 3/12= 63/12 ; 4 2/4= 18/4 so you have: (39/18) + (63/12) - (18/4) and then follow order of operation PEMDAS(remember you need common denominator to add or subtract fractions)
