Answer:
24.
Step-by-step explanation:
First, use the Order of Operations:
PEMDAS.
First, divide, then multiply to get your solution.
21 / 7 = 3.
3 · 8 = 24.
Therefore, your answer is 24.
Answer:
9,772,219 (Approx)
Step-by-step explanation:
Given:
Current population = 8,851,000
Growth rate = 2% = 0.02
a. Time = t
b. Time = 5 years
Find:
a. Write the equation.
b. Population after 5 year = ?
Computation:
a. Equation for the following question:
After population = 

b. Population after 5 year

The best part of this problem is that it has one unknown variable in the form of "x" and a single equation. So getting to the desired solution becomes very easy.
The equation given in the question is
10 - 5x = 20
- 5x = 20 - 10
- 5x = 10
- x = 10/5
- x = 2
Multiplying both sides with -1 we get
x = -2
So the value of x is -2. I hope the procedure is clear enough for you to understand.
Answer:
1/3
Step-by-step explanation:
Of the numbers between 1 and 12, the numbers that are multiples of 4 or 6 are: 4, 6, 8, 12.
So the probability is 4/12, or 1/3.
