What is the answer to 18 - 3w = 4w

Mathematics
1 answer:
adelina 88 [10]3 years ago
4 0

Answer:

Step-by-step explanation:

18 - 3w = 4w

Let's get all of the terms with the w on the right-hand side of the equation, and everything else on the left-hand side of the equation.

To do this, we should add 3w to both sides of the equation to remove the -3w from the left-hand side of the equation:

18 - 3w + 3w = 4w + 3w

18 = 7w

Finally, to get the w by itself, we can divide both sides by 7:

\frac{18}{7} = \frac{7w}{7}

w = \frac{18}{7}

Sharon buys four salmon steaks for $22.95 at her local supermarket. The weights of the steaks, in pounds, are 0.68, 0.74, 0.77,
Tema [17]

Answer:

$7.65

Step-by-step explanation:

Given that:

Money used for buying the four salmon steaks = $22.95

Weights of steaks in pounds = 0.68, 0.74, 0.77, and 0.81

To find:

Price of salmon steak per pound, to the nearest cent = ?

Solution:

Total weight of all 4 steaks = 0.68 + 0.74 + 0.77 + 0.81 = 3

Here, to find the price of salmon steak per pound we need to divide the total money used to buy salmon steaks with the total weight of salmon steaks in pounds.

Price of salmon steak per pound = \frac{22.95}{3} = \$7.65

√-225 • √-36 . show work.
Darya [45]

Answer:

±90

Step-by-step explanation:

√(-225) · √(-36) = (15i)·(6i) = 90i² = 90·(-1) = -90

_____

On the other hand, ...

... √(-225) · √(-36) = √((-225)·(-36)) = √8100 = 90

___

If you consider all the roots at each stage, the result is ±90. Since you're working with complex numbers here, it is reasonable to recognize every number has two square roots.

... √(-225) = ±15i

... √(-36) = ±6i

... √(-225) · √(-36) = (±15i)·(±6i) = ±90i² = ±90

Step-by-step explanation:

For P:

Number of hours off on 10 hours of working=0.4

Number of hours on 2080 hours of working=2080/10*0.4

=83.2 hours

For S:  

Number of hours off on 100 hours of working=7

Number of hours on 2080 hours of working=2080/100*7

=145.6 hours

The difference between the vacation hours of P and S is of 62.4 hours. S will get more hours of vacation.
