Answer:

x = 20

Step-by-step explanation:

these are vertical angles and vertical angles are congruent

3x+50 = 6x-10

3x = 6x - 60

-3x = -60

x = 20

A hot tub is being filled with water at a rate of 50 gallons per hour. Marcia's hot tub holds 400 gallons of water. The function

kodGreya [7K]

Answer:

<h3>5 hours</h3>

Step-by-step explanation:

Given the expression for the amount of water needed to completely fill the hot sub expressed as;

H(x) = 400 – 50x

x is the total number of hours

To get the number of hours it has been filling if it is still has 150 gallons to go, we will substitute h(x) as 150 and find x as shown;

150 = 400 - 50x

150 - 400 = -50x

-250 = -50x

x = -250/-50

x = 5

Hence it has been filling for 5 hours

Triangle QRS has medians QU, RV, and ST. If the measure of segment RW is 18 meters, what is the length of segment RV?

rodikova [14]

Answer: RV = 27 meters

Step-by-step explanation: Median is a line which unites a vertice and a midpoint of the opposite side. The point where, in a triangle, the medians intersect is called Centroid. The centroid divides the median in a ratio of 2:1, so Centroid Theorem states that the centroid of the triangle is at 2/3 of a distance from the vertex to the midpoint of the sides.

The attached figure shows the medians and centroid.

RW and WV are components of RV, the median.

If RW is 18 and following the theorem:

RW = $\frac{2}{3}$ .RV
