Which of the following inequalities has a solution x≥−3

1 answer:

6 0

Answer: A

Step-by-step explanation: 3(x-1) becomes 3x -3 ≤ 4x. Put all like variables on the same side, meaning you'll subtract 3x from both sides giving you -3 ≤ x. You can flip the equation around to make it look exactly like x ≥ -3

If a crew of 4 workers complete the job in 10 hours, how long will it take 5 workers to complete the same job?

Ulleksa [173]

We can solve using proportions
$\frac{4}{10} = \frac{5}{x}$
or 4 works is to 10 hours as 5 workers is to x hours.
to solve we cross multiply to get
$4x = 50 \\ x = \frac{50}{4}$
so it will take 5 men 12.5 hours!

Eric worked 13 hours last week at the library and earned $91.00. If he continues at the same hourly pay, how many more hours mus

skelet666 [1.2K]

19 hours

Calculate his hourly rate by dividing $91 by 13

hourly rate = $\frac{91}{13}$ = $7

Now divide $133 by 7 to find number of hours he has to work

$\frac{133}{7}$ = 19 hours
