What is -1/3+w=5 3/8 express in simplest form

Elodia [21]

Let's solve your equation step-by-step.
 $\frac{-1}{3}$ +w=5 $\frac{3}{8}$ 
Step 1: Simplify both sides of the equation.
w+ $\frac{-1}{3}$ = $\frac{43}{8}$ 
Step 2: Add $\frac{1}{3}$ to both sides.
w+ $\frac{-1}{3}$ + $\frac{1}{3}$ = $\frac{43}{8}$ + $\frac{1}{3}$ 
w= $\frac{137}{24}$ 

Answer:w=5 $\frac{17}{24}$

Westkost [7]

Answer by BlueSky06

The equation described above can also be written as, y = -x² + 100x + 4000To get the number of notebooks that will give them the maximum profit, we derive the equation and equate to zero. dy/dx = -2x + 100 = 0The value of x from the equation is 50. Then, we substitute 50 to the original equation to get the profit. y = -(50^2) + 100(50) + 4000 = 6500Thus, the maximum profit that the company makes is $6,500/day.

An ant walk about 3 inches per second how many miles per day could an ant travel if it walked without a break?

erastovalidia [21]

Answer:

Step-by-step explanation:

45/11 miles per day or ~4.091 miles per day

Step-by-step explanation:

3 inches per second

24 hours in a day

60 minutes in 1 hour

60 seconds in 1 minute

Amount of inches per minute: 3 x 60 = 180 inches

Amount of inches per hour: 180 x 60 = 10,800 inches

Amount of inches per day 10,800 x 24 = 259,200 inches

To find the number of feet that 259,200 inches is, divide by 12.

259,200/12 = 21,600 feet per day

To find the number of miles that 21,600 feet is, divide by 5280.

21,600/5280 = 45/11 = 4.09090909091 = ~ 4.091

So, an ant could walk 45/11 miles per day or ~4.091 miles per day if it walked without taking a break.
