Always work with the parenthesis first: so  work with the (2(x-3)+2)first and then the 5(x-3) then work out the like variables (2x-6+2) then,  use the distributive property on 3(2x-4). Then, work through all the like variables for your final answer. ...

1 2/5 would need to be turned into an improper fraction. So, 1 2/5 would be 7/5 then, 7/5-3/4 and to solve this you would need to get A common denominator which  in this case would be 20. So you final problem will be (28/20)-(15/20) =13/20

y^2 + x Evaluate when x = 1 and y = 2 y^2 + x is an expression with 2 variables. The problem gives you the value for x and y, so all you have to do is input the variables in.  So for x, write 1 And for y write 2 so, 2^2+1 =4+1 =5

When converting mixed fractions to improper fractions always remember to multiply the denominator to the whole number and then add the product to the numerator.  Here, -1 is the whole number, 7 is the numerator and 16 is the denominator. Keep in mind that the negative is for the entire...
