Answer:

Your answer is correct

Step-by-step explanation:

Indeed subtracting 5 from both sides would be n/-3> -1

Multiplying both sides by -3 would give you n < 3 (obviously after reversing the inequality sign)

Answer:

n

Step-by-step explanation:

We have been given an inequality \frac{n}{-3}+5>4. We are asked to solve the given inequality by explaining all the steps.

First of all, we will subtract 5 from both sides of inequality using subtraction property of inequality as:

\frac{n}{-3}+5-5>4-5

\frac{n}{-3}>-1

To solve for n, we will multiply both sides of inequality by -3. We need to remember that when we multiply or divide an inequality by a negative number, the sign of inequality reverses.

\frac{n}{-3}\cdot (-3)

n

Therefore, the solution of our given inequality would be n.

The rectangle is three times its width.
Airida [17]

Answer:

Length= 30 in

Width= 10 in

Step-by-step explanation:

Let the width of the rectangle be x in.

Length of rectangle

= 3 (width)

= 3x

Perimeter of rectangle= 2(length) +2(width)

80= 2(3x) +2(x)

80= 6x +2x

8x= 80 <em>(</em><em>simplify</em><em>)</em>

x= 80 ÷8 <em>(</em><em>÷</em><em>8</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>

x= 10

Thus width of rectangle= 10 in

Length of rectangle

= 3(10)

= 30 in

Sophie can type 128 words in 3 minutes. How many minutes will it take her to type 576 words
Alja [10]

Answer:

13. 5 minutes

Step-by-step explanation:

This is a simple proportion problem. Make two fractions where one item is always on the top and the other on the bottom.

\frac{3 min}{128 words} = \frac{x min}{ 576 words}

Now, cross multiply (multiply the two numbers diagonal from each other and divide  the diagonal with the x value)

576 x 3 = 1, 728

1, 728 / 128 = 13.5
