Answer:

PQ = 20

Step-by-step explanation:

Theorem: The length of the median of a trapezoid is the average of the base lengths.

$\frac{PQ + 12}{2} = 16$

PQ + 12 = 32

PQ = 20

See how easy that is if you know the theorem!

Devaughn is 15 years younger than Sydney. The sum of their ages is 73. What is Sydney’s age?

Olegator [25]

Answer:

Sydney is 44 years old

Step-by-step explanation:

Step 1: Make a system of equations

d = s - 15

d + s = 73

Step 2: Plug in s - 15 for d in the second equation and solve

s - 15 + s = 73

2s - 15 = 73 + 15

2s / 2= 88 / 2

s = 44

tester [92]

Hello there!

Answer: ⇒ C. -30

_________________________________________________________

Step-by-step explanation:

First you had to remove parenthesis.

$-7*4-|-6|+|4|$

Then you multiply by the number.

$=-28-|-6|+|4|$

Apply absolute value.

$|-6|=6$

$=-28-6+|4|$

Again apply absolute value.

$|4|=4$

$=-28-6+4$

Simplify it's should be the correct answer.

$=-30$
