Answer:

3a

Step-by-step explanation:

As the figure is a square, any given side will be parallel to the one that is opposite to it. Side CB is parallel to side AD, which extends from the origin point (0,0) to 3a. Given this fact, we can assume that AD has a length of 3a, and since all sides of a square are of the same length, we can assume the same length for side CB.

Hilda has $210 worth of $10 and $12 stock shares. The number of $10 shares is five more than twice the number of $12 shares. How
klasskru [66]
Let's first define variables.
 y: number of shares of $ 10
 x: number of shares of $ 12
 We write the system of equations:
 10x + 12y = 210
 y = 2x + 5
 Solving the system:
 x = 75/17
 y = 235/17
 Answer: 
 she has: 
 75/17 shares of $ 12 
 235/17 shares of $ 10

Plzzz help meeee plzzzzz plzzzz
Rasek [7]

Answer: A. 20%

Step-by-step explanation:

First, to find the total number of teachers, we can add 25+32+18+5+20=100

Next, we divide the number of teachers in 2014 (20) by the total number of teachers (100) as follows:

20 ÷ 100 = 0.2

Finally, to make 0.2 a percentage, we can multiply 0.2 X 100 = 20

Therefore, the correct answer is A.

In ∆abc, m∠cab = 2x and m∠​acb = x + 30. if line segment a b is extended through point b to point d, m∠​cbd = 5x − 50. what is t
Allisa [31]
The answer is option "3, 40".

<span>m∠cab = 2x
m∠​acb = x + 30
m∠​cbd = 5x − 50
Now,
</span>m∠cab + m∠​acb = m∠​cbd 
2x+x+30 = 5x-50
2x+x-5x = -50-30
-2x = -80
x = 40

Find the midpoint of (0, 4) and (2, -2)
lidiya [134]

Answer:

\text{Midpoint} = (1, \; 1)

Step-by-step explanation:

M = (x_M, \; y_M)

M = \left(\dfrac{x_1 + x_2}{2}, \; \dfrac{y_1 + y_2}{2}\right)

M = \left(\dfrac{0 + 2}{2}, \; \dfrac{4 + -2}{2}\right)

M = \left(\dfrac{2}{2}, \; \dfrac{2}{2}\right)

M = (1, \; 1)
