50 ! given: x - 6 1/3 ≤ 1 1/2. choose the solution set.
a.{x | x r, x ≤ 7 }
b.{x | x r, x ≤ 7 }
c.{x | x r, x ≤ 5 }

{x | x R, x ≤ 7 5/6 }

Step-by-step explanation:

we have

Convert mixed number to an improper fraction first

substitute

Multiply by 6 both sides to remove the fractions

Adds 38 both sides

Divide by 6 both sides

convert to mixed number

substitute

therefore

{x | x R, x ≤ 7 5/6 }

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'.
