Find the coordinates of the centroid of triangle RST. SHOW YOUR WORK so I can see if the answer makes sense (no links)
zimovet [89]

Note the coordinates of each point: R(-4, 5), S(5, 1), T(2, -3).

The centroid is the point whose coordinates are the average of the coordinates of R, S, and T.

<em>x</em>-coordinate: (-4 + 5 + 2)/3 = 3/3 = 1

<em>y</em>-coordinate: (5 + 1 - 3)/3 = 3/3 = 1

So the centroid is (1, 1).

3(negative 2-3x)=negative 9x-4
Andreyy89

Answer:

x = -2

Step-by-step explanation:

3(-2 - 3x) = -9x - 4 (Given)

3(-2) + 3(-3x) = -9x - 4 (Distributive Property of Equality)

-6 + 9x = -9x - 4 (Simplify)

-6 + 4 -9x= -9x - 4 + 4 (Addition Property of Equality)

-2 + 9x = -9x (Simplify)

-2 + \frac{-9x}{-9} = \frac{-9}{-9} (Division Property of Equality)

-2 = x (Simplify)

x = -2 (Symmetric Property of Equality)

adelina 88 [10]
You find the rates of each computer on its own...

One does the job in 55 minutes which we can say is 1/55

The other has a rate of 1/45.

The question wants to know how long it would take both working simultaneously to complete the job...

t/55+t/45=1

(9t+11t)/495=1

20t=495

t=24.75 minutes   (24:15)
