13+x+195=13(x+15)...

2 answers:

6 0

First, let's expand the right side. Now our equation is

$13+x+195=13x+195$

Now, we gather all the terms with x in it on the left side, and the numbers without x on the right. We get:

$-12x=-13$

And then we can make this

$12x=13$

We divide both sides by 12 to get x on its own, so x = 13/12 or 1.08

step 1 Simplify:x+208=13x+195
Step 2: Subtract 13x from both sides.x+208−13x=13x+195−13x−12x+208=195
Step 3: Subtract 208 from both sides.−12x+208−208=195−208−12x=−13S
Step 4: Divide both sides by -12.−12x−12=−13−12x=1312

Answer:x=13/12

5. Solve for x. I keep getting different answers ranging from 35 to 56

Anna35 [415]

Answer: 21

Step-by-step explanation:

x is a tangent line, 56-7 is a secant line. The length is equal to the outside segment times the entire segment. Notice that the length of the outside of the segment is equal to the entire segment for the tangent line.

$x^2=7(56+7)\\\\x^2=7(63)\\\\x=\sqrt{7(63)}\\\\x=\sqrt{7(7\cdot 9)}\\\\x=7\cdot 3\\\\\large\boxed{x=21}$

In AGHI, h = 300 inches, G=30° and H=29º. Find the length of i, to the nearest inch.

dalvyx [7]

Given:

In triangle GHI, h = 300 inches, G=30° and H=29º.

To find:

The length of i.

Solution:

We have, G=30° and H=29º.

Using angle sum property, we get

$m\angle G+m\angle H+m\angle I=180^\circ$

$30^\circ+29^\circ+m\angle I=180^\circ$

$59^\circ+m\angle I=180^\circ$

$m\angle I=180^\circ-59^\circ$

$m\angle I=121^\circ$

According to Law of sines,

$\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}$

Using Law of sines, we get

$\dfrac{h}{\sin H}=\dfrac{i}{\sin I}$

$\dfrac{300}{\sin 29^\circ}=\dfrac{i}{\sin 121^\circ}$

$\dfrac{300}{0.4848}=\dfrac{i}{0.8572}$

Multiply both sides by 0.8572.

$\dfrac{300}{0.4848}\times 0.8572=i$

$530.44554=i$

$i\approx 530$

Therefore, the length of i is about 530 inches.

Rectangle WXYZ was dilated to create W'X'Y'Z'.

Snezhnost [94]

You did not attach any picture to solve this problem. We cannot calculate for the value W’X’ without the correct illustrations. However, I think I found the correct one (see attached), please attach it next time.

So the first thing we have to do is to calculate for the dilation factor. Taking point G as the reference point, we can see that the distance of point G from rectangle W’X’Y’Z’ is 1.5 while the distance from rectangle WXYZ is (1.5 + 7.5), therefore the dilation factor to use is:

dilation factor = 1.5 / (1.5 + 7.5) = 1.5 / 9 = 1/6

Since WX has an initial measure of 3 units, therefore the measure of W’X’ is:

W’X’ = 3 units * (1/6) = 0.5 units

Answer:

0.5 units
