Answer:
a. 54.75
b. 2.64
Step-by-step explanation:
simplify each term
apply the distributive property
-X+3+(-X- -5)
multiple -1 by -5
-X+3+(-x+5)
remove unnecessary parentheses
-x+3-×+5
subtract x from -x
-2x+3+5
add 3 and 5.
-2x+8
42. Because you divide into 6 and 7. 6 is divided into 3 and 2. So, 2 times 3 times 7.
