If you are 16 years old then you are a teenager Question 14
To find out how many hours it rained, divide the total rise in the river by the amount it rose every hour.

First convert the mixed number into an improper fraction. We do this by multiplying the denominator to the whole number, adding it to the numerator, which becomes our new numerator, and we keep the denominator the same:

When dividing fractions we flip(the reciprocal) the one we're dividing by and multiply:

Multiply the numerators and denominators together:

Simplify by dividing:

So it rained for 10 hours.
(100-15)% = 85% = 136 students
136 / (85%) = 130*(100/85) = 160 students
Answer:
-x + 4
Step-by-step explanation:
(4x+5)+(−5x−1)
4x+5−5x−1 [Remove the parentheses]
-x + 4 [Combine Like Terms]
[-3,1)
-x-6<_-3 add 6 both sides
-x<_3 divide by negative 1 which means sign switches
x>_-3
-4x+3>-1 subtract 3 both sides
-4x>-4 divide by negative 4 which means sign switches
x<1
1 is the greater bound meaning x can’t be larger than 1
the sign doesn’t include 1 so it’s the parenthesis in interval notation
-3 is the lower bound meaning x can’t be -3 or less than -3 so the interval notation is
The sign includes -3 so it’s brackets in interval notation
