what is the solution to the equation fraction 4 over 5 n minus fraction 3 over 5 equals fraction 1 over 5 n? n = 1 n = −3 n = fraction 3 over 4 n = fraction 1 over 4

Answers

Answer 1

Answer: $(4)/(5)n-(3)/(5)=(1)/(5)n\ \ \ \ \ |multiply\ both\ sides\ by\ 5\n\n4n-3=n\ \ \ \ |add\ 3\ to\ both\ sides\n\n4n=n+3\ \ \ \ |subtract\ n\ from\ both\ sides\n\n3n=3\ \ \ \ |divide\ both\ sides\ by\ 3\n\n\boxed{n=1}$

Answer 2

Answer:

Answer:

The correct result would be n = 1.

Step-by-step explanation:

4/5n - 3/5 = 1/5n /*5n

4 - 3/5 * 5n = 1

4 - 3n = 1

4 - 1 = 3n

3 = 3n

n = 1

Faucet a can fill a water cooler 8 minutes. faucet b can fill the same cooler in 12 minutes. how long will it take both faucets together to fill the water cooler?

Answers

This is a work problem. We can use theories on ratios and proportion in order to solve this. We do as follows:

Faucet A = 8 minutes to fill
Faucet B = 12 minutes to fill

1/8 + 1/12 = 1/x

let x represent the time it takes for both to fill the cooler

x = 4.8 minutes for both to fill the cooler

Help me on this question please!An inequality is shown below:

−np − 6 ≤ 3(c − 5)

Which of the following solves for n?

n ≥ − the quantity 3 times c minus 21 all over p
n ≥ − the quantity 3 times c minus 9 all over p
n ≤ − the quantity 3 times c minus 21 all over p
n ≤ − the quantity 3 times c minus 9 all over p

Answers

Answer:

The correct option is B) $n\geq (-3c+9)/(p)$ .

Step-by-step explanation:

Consider the provided inequality:

$-np - 6 \leq 3(c - 5)$

Now distribute 3 inside the parentheses.

$-np - 6\leq 3c - 15$

Add 6 on both the side of the inequality:

$-np-6+6\leq 3c-15+6$

$-np\leq 3c-9$

Now, multiply both the sides by a negative sign and reverse the sign of inequality.

$np\geq -3c+9$

Divide both the sides of the inequality by p.

$n\geq (-3c+9)/(p)$

Now consider the provided options.

By observing the provided option it can be concluded that the correct option is B) $n\geq (-3c+9)/(p)$ .

Solve each system of equations by graphing y=-1/2x+5 and y=3x-2

Answers

just make the equations equal to each other. -0.5x+5=3x-2. Solve for x and find that it is 2, via simple algebra. Since you know x is 2, sub it in in either equation to find y. y should be 4. So the point that fits both equation is (2,4). This shows that the two graphs of these lines will intersect at this exact point.

If you were to graph these two lines, you ould see that the point of intersection is at (2,4) like we solved for.
