Question

Which of the following phrases are equations? Choose 2 answers:

a) 5 = 3m
b) n > |-8|
c) 2 + 6 = (5 - 1) * 2
d) 8 * (k + 6)
e) 0 < 4 + p

Answer 1

The phrases that are equations are a) 5 = 3m and c) 2 + 6 = (5 - 1) * 2 because they contain an equals sign and express equality between two expressions.

Step-by-step explanation:

The question asks to identify which of the listed phrases are equations. An equation is a mathematical statement that asserts the equality of two expressions. Looking at the options provided:

• a) 5 = 3m is an equation because it has an equals sign (=) that shows a relationship of equality between two expressions (5 and 3m).
• b) n > |-8| is not an equation, but an inequality because of the greater than sign (>).
• c) 2 + 6 = (5 - 1) * 2 is an equation as it shows the sum of 2 and 6 is equal to the product of (5 - 1) and 2, affirmed by the equals sign (=).
• d) 8 * (k + 6) is not an equation because it doesn't have an equals sign, it is an expression.
• e) 0 < 4 + p is not an equation, but an inequality because of the less than sign (<).

Therefore, the phrases which are equations are a) 5 = 3m and c) 2 + 6 = (5 - 1) * 2.
