Answer:
4) A
5) E
Step-by-step explanation:
#4


Cross multiply the equation and you get:

Since
is the same thing as
, you can change the equation into 
Cancel out the y on the top and bottom and you get 1/10
#5
, simplify and you get
so x=15
is equal to
after you plug in x, and that is equal to 9
Answer:
D. y= -4x +5
Step-by-step explanation:
- The equation
can be transformed by doing some algebra. - If we solve the second term of the equation -4(x-2)= 8 - 4x, then we have
(this is done by distributing the multiplication into the two terms: remember that the product of -4x(-2)=+8 because the product of two negative numbers is a possitive number). - Then, by subtracting both sides 3, we have
. Rearranging terms in the right side, we have
, which is option D.
Answer:
271.5
Step-by-step explanation:
100-55=45
45% of 187
187*45=8415
