Find x for equation 10 points

alexgriva [62]

Hi!

3x - 30 = x + 10

<h3>Solve by isolating x on one side. </h3><h3>Add 30 to both sides. </h3>

3x - 30 + 30 = x + 10 + 30

3x = x + 40

<h3>Subtract x from both sides. </h3>

3x - x = x - x + 40

2x = 40

<h3>Divide by 2 on both sides</h3>

2x/2 = 40/2

<h2>The answer is x = 20</h2>

Hope this helps! :)

Triangle FGH has the following side lengths: FG = 5 ft, GH = 10 ft, HF = 12 ft Triangle PQR is similar to triangle FGH. The long

7nadin3 [17]

The first thing we must do for this case is find the scale factor.
We have then that for the larger side of both triangle, the scale factor is:
$k = \frac{RP}{HF}$
$k = \frac{7.2}{12}$
$k = 0.6$
To find the other two sides, we must apply the scale factor on each side of the triangle FGH.
We have then:

For PQ
$PQ = k * FG

PQ = 0.6 * 5

PQ = 3$

For QR
$QR = k * GH

QR = 0.6 * 10

QR = 6$

Answer:
You have that the lengths for the other two sides of triangle PQR are:
$PQ = 3

QR = 6$
