Question

Find mZKJL. K 7x (3x + 16)0M mZKJL =

Answer 1

Answer:

The answer is 28.

Step-by-step explanation:

Ok.

☆7x and 3x + 16 are congruent, meaning they equal the same.

☆Since they are equal, we can make an equation out of then.

7x = 3x + 16

☆Then we just solve.

$\: \: \: \: \: \: \: \: \: 7x = 3x + 16 \\ \frac{- 3x = - 3x}{4x = 16} \\ \\ \frac{4x}{4} = \frac{16}{4} \\ \\ x = 4$

☆Therefore, x equals 4.

☆We are solving for m<KJL so all we need to do is plug in.

$7x \\ 7(4) \\ 28$

☆You answer is 28.
