Which shows one way the equation can be represented in words?

z minus 6 = 1.4
a. The difference of a number and z is the same as one and four-tenths.
b. A number subtracted from one and four-tenths is equal to six.
c. Six less than a number is the same as one and four-tenths.
d. Six decreased by a number is equal to one and four-tenths.

The answer is C. Six less than a number is the same as one and four-tenths.

Step-by-step explanation:

Six represents the number 6.

"z" represents a number.

"Same as one and four-tenths" is referring to the part of the equation that says = 1.4

So happy I could help :)

x is the total time in minutes for the free response
