Answer:
-4
Step-by-step explanation:
Numbers decrease on a number line as you go left. So, to find a number to the left of -1, you need to find a number that is smaller. Since negative numbers decrease in value as they get further from 0, -4 must be smaller than -1. All other values listed will be to the right of -1.

Multiply both sides by 3

Simplify the numerators

Multiply both sides by 6

Simplify the numerator

Multiply both sides by x
12x - 18 = 15x Subtract 12x from both sides
-18 = 3x Divide both sides by 3
-6 = x Switch the sides to make it easier to read
x = -6
Check your answer by plugging -6 in for the x in the original problem:

Plug in -6 for x

Change

to

so all denominators are the same

Change

to

for easier work

Subtract the numerators (4 - (-1) )

=

So,
x = -6 .
Answer: B. 11%
Step-by-step explanation:
Let A = Event that students eat breakfast in the morning.
B= Event that students floss their teeth.
We are given P(A)=57%=0.57
P(B)=80%=0.80
P(A∩B) = 46% =0.46
Now, the probability that a student from this class eats break feast but does not floss their teeth :-

Hence, the probability that a student from this class eats break feast but does not floss their teeth= 11%
