D) 4/5
Because the lace is 3.2 ydlong, so 3.2÷4=4/5
Step-by-step explanation:
a. y = ¾x +6
b. y = 6/4 x -2
c. y = -2/4 x +3
d. y = -1/7 x -4
Four times a number would equal 4n
85% liked => 15% didn't like
30 = 15% of x
30 = 0.15 x => x = 30 / 0.15 = 200. This is the total number of students at the library.
Then 200 - 30 = 170 is the number of students whom did like reading mistery stories.
Answer: 170.
you are solving for slope so what you would do is y1-y1/(x1-x2)=m
m being the slope or rate of change and you assign each point to be your "1" and "2"
