Answer:

-60

Step-by-step explanation:

-3(x + 10) + 2x = 30 becomes -3x - 30 + 2x = 30 after having performed the multiplication. Combining like terms, we get -x = 60, so that x must be -60 (Answer 4)

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).

A boat costs $12,250 & decreases in value by 11% per year how much will the boat be worth after 4 years

kirill115 [55]

So it decreases by 11% which means by the next year it's worth 89% of the original price, write 89% like a decimal. then put it to the power of 4 (4 years) and multiply by the original number
.89 ^ 4 * 12250 = 7685.92

The diameter of a sphere us 4 centimeters. which represents the volume of the sphere

Veronika [31]

Greetings and Happy Holidays!

The Formula for the Volume of a Sphere is: $V=\frac{4}{3}\pi r^3$

Input the value of the radius ( $\frac{d}{2}$ ):
$V=\frac{4}{3}\pi (2)^3$

Solve using the Order of Operations:
$V=\frac{4}{3}\pi (8)$

$V=\frac{4}{3}\pi \frac{8}{1}$

$V=\frac{32}{3}\pi$

The Answer Is:
$\boxed{V=33.510322}$

I hope this helped!
