Question

Evaluate (z over 7x) when x = 5 and z = 7.
a) 0.2
b) 0.4
c) 1
d) 1.4

Answer 1

Substituting the given values into the expression (z over 7x), with x=5 and z=7, and simplifying it leads to the answer 0.2.

Step-by-step explanation:

To evaluate (z over 7x) when x = 5 and z = 7, substitute the given values into the expression, which leads to (7 / (7 * 5)). Simplify by dividing 7 by 7, which equals 1, and then divide by 5. Therefore, the result is 1/5, which can also be expressed as 0.2. So, the correct answer is a) 0.2.
