what does X equal? 3/ax - 4 = 20
X=
Answer:
3/ax-4=20
first add 4 to both sides
3/ax=20+4
multiply by a/3
24a/3
so x=8a
Answer: 1/8a
Step-by-step explanation: add 4 to both sides first, which will give you 3/ax = 24. Now multiply both sides by ax/3 to get rid of the 3/ax, which will then give you 1 = 24 * ax/3, which equals to 1 = 24ax/3. This can be simplified further and you'll get 1 = 8ax. now divide both sides by 8a to isolate x, you will end up with 1/8a = x.

20. The population of a town increased from 60,450 to 95,610 in one decade. What was the
relative change of the population?
(a) 58.2% (b) 36.8% (c) 158.2% (d) -36.8%
A. 58.2%
this is because
(95610-60450)/60450 =0.5816377171215 which rounds to 0.582 which is 58.2%
Answer:
A
Step-by-step explanation:
Change in population/ original number
[tex]\frac{95610 - 60450}{60450}[/tex] = [tex]\frac{35160}{60450}[/tex] = .58163771712 This is the answer as a decimal. Multiple this by 100 to get 58.2% increase rounded to the nearest tenth of a percent.

What is inequality form ?
The notation a ≠ b means that a is not equal to b; this inequation sometimes is considered a form of strict inequality. It does not say that one is greater than the other; it does not even require a and b to be member of an ordered set.
What is interval notation?
Interval notation is a way to describe continuous sets of real numbers by the numbers that bound them. Intervals, when written, look somewhat like ordered pairs. However, they are not meant to denote a specific point. Rather, they are meant to be a shorthand way to write an inequality or system of inequalities.

What is a bank?An example of a financial institution that lends money is a bank, which both collects deposits from the public and creates demand deposits. Through the capital markets, the bank may engage in lending activities directly or indirectly.
Banks are heavily regulated in most countries because they are essential to the financial stability and economic health of a nation. The fractional reserve banking system, in which banks maintain liquid assets that are only partially comparable to their current liabilities, has been institutionalized in the majority of countries. In addition to other constraints intended to assure liquidity, banks are often subject to minimum capital requirements based on an international set of capital norms known as the Basel Accords.

Meena drove 245 miles in 5 hours. if she continued at the same rate, how long would it take to travel 196 miles
Meena would take 4 hours to drive 196 miles.
We will begin with calculation of number of miles Meena drives in 1 hour. We need to perform division as per the formula given below to find the speed. Then we will calculate the time required for driving 196 miles.
So, formula stating rate or speed of driving -
Speed = distance ÷ time
Keep the values in formula to find the speed
Speed = 245 ÷ 5
Performing division
Speed = 49 miles per hour
So, Meena drives 49 miles in 1 hour.
For driving 196 miles, the time required = (1 ÷ 49) × 196
Performing multiplication and division
Time required = 4 hours
Hence, Meena will require 4 hours to drive 196 miles.

reggie drew a scale drawing of a swimming pool. the scale of the drawing was 4 millimeters : 3 meters. the pool is 24 meters long in real life. how long is the pool in the drawing?
The pool that Reggie drew will be 24 millimeters long, compare to real life which is 24 meters long.
As we can't create a real-life dimension in a small sheet of paper, we opted for a small scale that covers up the large length. As we are given, the scale of the drawing is 4 millimeters: 3 meters, which means 1 millimeter is equal to 3/4 meters, and the size of the pool in real life is 24 meters.
So, the length of the pool in the drawing is = 24*(3/4)
= 24 millimeters
