Sagot :

Answer:

substitute the given values for m, n, and p into each problem and solve. Make sure you don't ignore minuses and negatives. Separate with parentheses to make sure you don't get confused.

Step-by-step explanation:

54:   -7(-5) - 10( 3/2)

         35   -  10(1.5)

         35   -   15

                20

55.    -3mnp

         -3 x (-5) x 3/2 x (-8)

                15   x  1.5  x (-8)

                        22.5 x (-8)

                             -180

56.        8n / (-6p)

             8(1.5) / (-6 x -8)

                12   /  48

                1/4 or .25

57.          p squared is (-8)(-8)  

             2(-8)(-8)(-1.5) / (-5)

                 128 (-1.5)    / (-5)

                     -192/ (-5) negatives cancel out

                       192/5

                        38.4
