Difference between solutions of linear equations and solutions of linear in equalities
Answers
One obvious difference between linear equations and inequalities is the solution set. A linear equation of two variables can have more than one solution.
For instance, with x = 2_y_ + 3, (5, 1), then (3, 0) and (1, -1) are all solutions to the equation.
In each pair, x is the first value and y is the second value. However, these solutions fall on the exact line described by y = ½ x – 3/2.
If the inequality were x ? 2_y_ + 3, the same linear solutions just given would exist in addition to (3, -1), (3, -2) and (3, -3), where multiple solutions can exist for the same value of x or the same value of y only for inequalities. The "?" means that it is unknown whether x is greater than or less than 2_y_ + 3. The first number in each pair is the x value and the second is the y value.

The rationalnumber between 1/8 and 1/4 is 3/16.
We have,
To find a rationalnumber between two given fractions, we can take their average.
In this case, the given fractions are 1/8 and 1/4.
The average of two fractions is found by adding them together and dividing by 2.
So, we have (1/8 + 1/4) / 2.
To add the fractions, we need a common denominator, which in this case is 8.
1/8 + 1/4 = 1/8 + 2/8 = 3/8.
Then, we divide 3/8 by 2 to find the average:
(3/8) / 2 = 3/8 * 1/2 = 3/16.
Therefore,
The rationalnumber between 1/8 and 1/4 is 3/16. It lies exactly halfway between the two given fractions on the number line.

Markup refers to the amount added to the cost price to cover overheads and profit. So for example a 50% markup on a $10 product would mean adding 50% of $10 onto the sale price. As fractions can be written as decimals (50% = 0.5) and we are adding on the amount of markup to the initial cost we can also phrase this as 10 x 1.5 = 15
For your question the markup would become 1.1 and the initial cost is 2.7, remembering we must add 1 to the markup to cover the initial cost
2.7 x 2.1 = 5.67
