The formula of a midpoint:

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

D is midpoint of TR.

We have T(-2a, 0) and R(-2b, 2c). Substitute:

x=\dfrac{-2a+(-2b)}{2}=\dfrac{-2a-2b}{2}=\dfrac{2(-a-b)}{2}=-a-b\\\\y=\dfrac{0+2c}{2}=\dfrac{2C}{2}=c

<h3>Answer: b.  (-a - b, c)</h3>

The sum of two numbers is 136 one number is 51 what is the other number? What are the common factors of these two numbers?
Rom4ik [11]
The sum of two numbers is 136 (sum is what you get when you add two numbers together). If one of the two numbers is 51, and the other number is X, then:

X + 51 = 136

To solve for x we subtract both sides by 51.

X + 51 -51 = 136 - 51
X = 85

The other number is 85.

What are the common factors of these two numbers?
Factors are the numbers that multiply to make the product.

Factors of 51: 1, 51, 3, 17
Factors of 85: 1, 85, 5, 17

Answer:

quarters are 20 in number.

Step-by-step explanation:

Let <em>d</em> represent dimes

Let <em>q</em> represent quarters

d + q = 35

q = d+5

d+d+5=35

2d=35-5

2d =30

d = 30/2

therefore dimes =15

Substitute d for 15 to solve for q;

q=15+5

therefore quarters are 20 in number.
