The inequality x - 4 ≥ 8 represents the sentence " the sum of a number and -4 is at least 8" and the solution of the inequality is the value of variable x is x ≥ 12.
<h3>What is inequality?</h3>
Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
Let's assume that the number would be x
The sum of a number and -4 is at least 8
According to the given question, translate the phrase into an algebraic form :
x - 4 ≥ 8
Add 4 both sides of the above inequality,
x - 4 + 4 ≥ 8 + 4
x ≥ 12
Therefore, the inequality x - 4 ≥ 8 represents the sentence " the sum of a number and -4 is at least 8" and the solution of the inequality is the value of variable x is x ≥ 12.

Answer:
There is no answer. The equation cannot be simplified any further.
Answer:
See work below.
Step-by-step explanation:
There are 20 total blocks. 6 of them are painted. We can divide 6 by 20 and multiply that number by 100 to find the percentage of painted blocks.
6/20 = 0.3
Now, we need to multiply by 100 to convert to a percentage.
0.3 x 100 = 30%
The three-day weighted moving average for the price of the stock at the end of Day 7 is 57.17.
<h3>How do we calculate a weighted moving average?</h3>
Note that since this is for the end of Day 7, it implies that the actual Day 7 Stock Price is not yet known at the time of the calculation and we need to forecast it.
Therefore, the most recent price is Day 6 Sock Price and a three-day weighted moving average for this question can be calculated as follows:
Three-day weighted moving average = ((Day 6 Sock Price * 3) + (Day 5 Sock Price * 2) + (Day 4 Sock Price * 1)) / (3 + 2 + 1)
Three-day weighted moving average = ((55.00 * 3) + (59.00 * 2) + (60.00 * 1)) / (3 + 2 + 1)
Three-day weighted moving average = 57.17
