Hugh says that “one less than four times a number” can be written as two expressions: 1 - 4n and 4n - 1. Why is Hugh incorrect? A
because no two expressions are equal

B
because subtraction is not commutative

C
because Hugh forgot to include equal signs

D
because coefficients go after their variables

B) Because subtraction is not commutative

Step-by-step explanation:

Let take an example, say, ‘Four minus three’

=> 4 - 3

=> 1

This is true, but on the other hand, if we make it 3 - 4

=> 3 - 4

=> -1

Hence, we find out that 4-3 ≠ 3-4

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
