Question

the equivalent expression of 20(−1.5r+0.75)

Answer 1

Answer:

-15 / Please read and try to figure out the problem down in the explanation so you don't have trouble in the future.

Step-by-step explanation:

So first step is to follow PEMDAS or Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction. Since Parenthesis comes first you do what is in the parenthesis. Which is (-1.5+0.75), but in order to do this you must have the decimal points in the same spot which 1.5 and 0.75 are different, so you must re-write -1.5 as -1.50 (1.5 is the same as 1.50). Second when adding negative numbers and positive numbers  the answer is always negative no matter what. So you should get -0.75 or -.75. since  the 20 it right next to the parenthesis you have to multiply 20 by -0.75 which is -15.

-1.50

 0.75
