Answer:
Step-by-step explanation:
Like your other question, let's break it down systematically
6x + 9y - 9(6x - 3y + 8z)
Use the distributive property
6x + 9y - <u>9(6x - 3y + 8z)</u>
6x + 9y - 54x - 27y + 72z
Match like terms
6x - 54x = -48x
9y - 27y = -18y
72z - 48x - 18y
Answer:
initial speed: 240 m/h
Step-by-step explanation:
48 m/h is the current speed which is the 20% of X
x (20 / 100) = 48
20x = 4800
x = 4800/20
x = 240 m/h
Yes no yes yes no
hope it helps
Y=4
the answer is y=4 because you had to subtract 8 from both sides.
