In the problem 3/4 • N=1, n must be
Serggg [28]

3/4 x n=1......n equals 4/3.

In order for n to equal 1 you have to find a number that will make 3/4 a whole number after you multiply it. Usually in problems like these the answer is usually the fraction but flipped around. So 3/4 and 4/3....when you multiply the    numerators you get 12 and when you multiply the denominator you get 12 so 12/12, which equals 1. hope that makes sense.

Assume you have sea water that weighs 64 lb/ft³ and contains 35 parts per thousand (0.0035) dissolved salt by weight. How many c
zlopas [31]

Answer:

558.036 lb

Step-by-step explanation:

Let x is the amount of the sea water to collect 125 lb of sea salt

As given: 64 lb/ft³ has 0.0035 dissolved salt by weight

So the formula to find out the amount of the sea water is:

64 lb/ft³ * 0.0035 *x ft³  = 125 lb

<=> x = \frac{125}{64*0.035} = 558.036 lb

Hope it will find you well.

Misha Larkins [42]

<u>Answer:</u>

The answer is D : 4.

<u>Step-by-step explanation:</u>

<em>=2x-3>11-5x</em>

<em>=2x-3+5x>11</em>

<em>=7x>11+3</em>

<em>=7x>14</em>

<em>=7x/7>14/7</em>

<em>=x>2</em>

<em />

<em />

<em>By simplifying the problem, you can see that "x" </em><em><u>must</u></em><em> be greater than 2. Therefore, eliminating all other possible answers that are shown, but 4. </em>
