Final answer:
None of the given expressions has a value of 4. The correct answer is a) 16 - 12W.
Step-by-step explanation:
To find the expression that has a value of 4, we need to evaluate each option.
a) 16 - 12W: To find the value of W, we need more information. The expression cannot be simplified to 4.
b) -1 - 4: This expression simplifies to -5, which is not equal to 4.
c) (96 ÷ 8) – 23: 96 ÷ 8 = 12, and 12 – 23 = -11, which is not equal to 4.
d) 24 - 42: This expression simplifies to -18, which is not equal to 4.
Therefore, none of the given expressions has a value of 4.
Equations are mathematical statements that assert the equality of two expressions. They typically contain variables, constants, and mathematical operations like addition, subtraction, multiplication, division, exponents, and more. Equations are solved to find the value(s) of the variables that satisfy the equality.
