Mathematics

Answer:

g = 7 + 9e - 3e /4

Step-by-step explanation:

3e + 4g = 7 + 9e

Subtract 3e from both sides to eliminate 3e on the left side

3e - 3e + 4g = 7 + 9e - 3e

4g = 7 + 9e - 3e

Divide both sides by 4 to isolate g

4g/4 = 7 + 9e - 3e /4

g = 7 + 9e - 3e /4

Suppose KLMN ~ PQRS. Find the value of x.
arlik [135]

Complete question is attached.

Answer:

B) 8

Step-by-step explanation:

In this question, KLMN ~ PQRS. This means they are similar shapes.

From the image, we could denote that:

KL ~ PQ

LM ~ QR

Given that:

KL = 12

PQ = 30

QR = 20

LM = x

To find x, let's use tge expression:

\frac{KL}{PQ} = \frac{LM}{QR}

=  \frac{12}{30} = \frac{x}{20}

Cross multiplying, we have:

12 * 20 = 30x

240 = 30x

To find x, let's divide both sides by 30.

\frac{240}{30} = \frac{30x}{30}

8 = x

x = 8

The correct option is option B.
