Step 1: Write down the decimal divided by 1, like this:

decimal

Step 2: Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)

Step 3: Simplify (or reduce) the fraction

Answer:

Step-by-step explanation:

$-\dfrac{3}{4}(x+2)=6\qquad\text{multiply both sides by 4}\\\\4\!\!\!\!\diagup^1\cdot\left(-\dfrac{3}{4\!\!\!\!\diagup_1}\right)(x+2)=4\cdot6\\-3(x+2)=24\qquad\text{divide both sides by (-3)}\\\\\dfrac{-3\!\!\!\!\diagup^1(x+2)}{-3\!\!\!\!\diagup_1}=\dfrac{24}{-3}\\\\x+2=-8\qquad\text{subtract 2 from both sides}\\\\x+2-2=-8-2\\\\x=-10$

Can someone explain how to do this cuz my computer ain’t doing such a good job

Answer:

L=36

W=6

Step-by-step explanation:

If the length is six times the width than the width is equal to x. This would make the length 6x or 6 times x. The perimeter of the rectangle is all of the sides added together. So 6x+6x+x+x=14x

The perimeter equals 84 which gives you

14x=84

Divide by 14 on each side and x=6

The length is six times longer than the width which is 6x6 or 36 and the width would just remain 6.

Square A B C D is shown. Each side is 30 yards long. A diagonal is drawn from point D to point B to form 2 triangles.

Answer:

Length = 30√2 yards.

Step-by-step explanation:

There is a plot of land of square shape that has 30 yards on each side. Jules owns this plot. He plans to divide the land in half by building a fence along the diagonal of the plot.

We have to calculate the length of the fence.

Now, the length of the diagonal will be the length of the fence.

So, the length = $\sqrt{30^{2} + 30^{2}} = 30\sqrt{2}$ yards. (Answer)
