Answer:
Step-by-step explanation:
In order to solve for x, she had to first subtract 6 on both sides of the equation. Then divide by 5 on both sides of he equation. After the division part, she was able to successfully isolate x.
The equation she had to solve was (C) 5x+6=21
First step: Subtracting 6 on both sides of equation resulted in
5x = 15
Second step: Dividing both sides of the equation by 5 resulted in
x = 3
Using the uniform distribution, considering that the novel has 435 pages, the probability that the page is numbered something between 21 and 31 is:

<h3>What is the uniform probability distribution?</h3>
It is a distribution with two bounds, a and b, in which each outcome is equally as likely.
The probability of finding a value between c and d is:

Researching the problem on the internet, it is found that the novel has 435 pages, hence a = 0, b = 435, and the probability that the page is numbered something between 21 and 31 is given by:

Answer:
Step-by-step explanation:
Answer: 4 / 5
Explanation:
1) For a right triangle, the ratio sine is defined as:
sin(x) = opposite-leg / hypotenuse
2) x is the angle. In this case: A
3) As per the figure, the opposite leg to tha angle A measures 28
4) As per the figure, the hypotenuse measures 35
5) Calculations:
sin(A) = 28 / 35
Simplify dividing both numerator and denominator by 7 => 28/35 = 4/5
