<h3>Answer: 51/99</h3>

=================================================

Work Shown:

x = 0.515151...

100x = 51.515151....

Subtract the two equations to get 100x-x = 99x on the left side and 51.515151.... - 0.515151... = 51 on the right side. Notice the decimal portions cancel out.

So we end up with 99x = 51 which solves to x = 51/99

This means 51/99 = 0.515151...

Answer:

17/33

Step-by-step explanation:

We first let 0.51 be x.

Since x is recurring in 2 decimal places, we multiply it by 100.

100x=51.51

Next, we subtract them.

100x−x=51.51−0.51

99x=51

Lastly, we divide both sides by 99 to get x as a fraction.

x=51/99

=17/33

The computation shows that the acres that are in the lot will be 1.38 acres.

<h3>How to compute the value?</h3>

It should be noted that the information is that the house is on a 60,000-squarefoot and the there are 43,560 square feet in an acre.

Therefore, the acres in the lot will be:

= 60000/43560

= 1.38 acres

Therefore, the computation shows that the acres that are in the lot will be 1.38 acres.

Find the value of x.<br><br> (x + 4)<br> 147°
larisa86 [58]

Answer:

<h2>x = 29°</h2>

Step-by-step explanation:

From the question the angles lie on a straight line which means that the sum of their angles add up to 180°

Since angles on a straight line add up to 180°

To find the value of x add up all the angles and equate it to 180 to find x

That's

x + 4 + 147 = 180

x + 151 = 180

x = 180 - 151

We have the final answer as

<h3>x = 29°</h3>

Hope this helps you
