0.8(5x+15)=2.6-(x+3)

Mathematics

0.8(5x + 15) = 2.6 - x + 3   Use the Distributive Property
       4x + 12 = 2.6 - x + 3   Combine like terms (2.6 and 3)
       4x + 12 = 5.6 - x         Add x to both sides
       5x + 12 = 5.6              Subtract 12 from both sides
              5x = -6.4             Divide both sides by 5
                x = -1.28

Jada walks up to a tank of water that can hold up to 10 gallons. When it is active, a drain empties water from the tank at a con
Arte-miy333 [17]

Answer:

  • 4.5 minutes

Step-by-step explanation:

At time zero the level was 7 gallons and at time 3 min, the level was 5 gallons.

<u>Take two points:</u>

  • (0, 7) and (3, 5)

<u>Find the rate of change:</u>

  • m = (5 - 7)/3 = 2/3

This is a 2 gallons per 3 minutes

<u>Tank holds 10 gallons, it was emptied by 3 gallons and it took:</u>

  • 3 : (2/3) = 3* 3/2 = 4.5 minutes

Find the median:<br> 3, 5, 7, 4, 3, 1
vitfil [10]
<h3>Answer: 3.5</h3>

=========================================

Explanation:

Start by sorting the values from smallest to largest. This is known as ascending order. The original set {3, 5, 7, 4, 3, 1} will sort to {1, 3, 3, 4, 5, 7}

After the values are sorted, we will look at the middle most value to find the median. Because there are six items in this data set, the median number is between slot 3 and slot 4. Note how the sorted data set breaks down into

{1, 3, 3} and {4, 5, 7}

we see that 3 and 4 are tied for the middle most, so the median must be 3.5 which is halfway between 3 and 4.

Shania and Pedro are discussing whether it is always possible to solve a right triangle, given enough information, without using
Makovka662 [10]

Answer: Shania is correct.

Step-by-step explanation:

For a right angled triangle, given two sides and an angle, we can use the sine rule or the various trigonometry identities to solve the triangle;

a/sin A = b/sinB

and

sin (angle) = opposite side/hypotenuse

cos (angle) = adjacent side/hypotenuse

tan (angle) = opposite/ adjacent

assuming a is the opposite side of angle A and b is also opposite of angle B

Otherwise, the only way to solve a triangle given two sides only is by the use of the Pythagoras theorem.

Hence, Shania is correct.

The equation is not setup properly, possibly it is your teacher's fault.

From external research, I would say the answer is x = -12.
