-9n plus 9n is zero 3-8 is -5
Answer:
see below
Step-by-step explanation:
19. -9 x = -117
20. -¹/₈ x = -³/₄
21. ⁵/₆ x = -⁵/₉
---------------------
19.
x = 117 / 9
x = 13
20.
x = ³/₄ divide ¹/₈
x = 6
21.
x = -⁵/₉ divide ⁵/₆
x = -²/₃
Step-by-step explanation:
the reason it's D is because "inelastic" means it doesn't change while the rest of the answers are more dependent on chance, D shows a truck driver doing something consistent and unchanging.
First you need to simplify it so
5 7/8 = 5x8=40 40+7=47 so at the moment you have 47/8
then do
11/4 is fine so find the common denominator
in this case its 8 so 4x2=8 and then 11x2=22 so you have 47/8-22/8
which = 25/8 then you simplify and you get <em><u>3 1/8</u></em>
