Solve for x 7x-4+4y+8=24+31

Mathematics
1 answer:
Anastasy [175]3 years ago
4 0

Answer:

x = -4y/7 + 51/7

Step-by-step explanation:

First, you add all the numbers without variables and are on the same side.

7x - 4 + 4y + 8 = 55

Then you do the opposite sign (for example the opposite of addition is subtraction) of the two numbers without variables on the left side to add them to the right side(what you do on one side of the equation you must do on the other.

4x - 4 + 4 + 4y + 8 - 8 = 55 + 4 - 8

4x + 4y = 51

Then you get the x by itself by doing the same thing you did with the last step by this time with 4y.  Because this has a variable, you don't add it onto the 51, but add as a different number.

4x + 4y - 4y = 51 - 4y

4x = -4y + 51

Now to isolate the x, you divide 4x by 4.

4x/4 = -4y/7 + 51/7

x = -4y/7 + 51/7

Your answer is x = -4y/7 + 51/7

Iteru [2.4K]

Answer:

Step-by-step explanation:

(Tangent Length)^2 = y*(y + 11)   You are going to have to use the quadratic formula on this.

Tangent Length = 7

7^2 = y * (y + 11)

49 = y^2 + 11y  

0 = y^2 + 11y - 49

a = 1

b = 11

c = - 49

When you solve this quadratic equation you get

x1 = 3.40 which is the answer you go with.

x2 = -14.40 which can't be used. A negative length has no meaning.

A pipe fills 11/15 liters of tub in 22/45 minutes. What is it's flow rate in terms of liters per minute?
Lelu [443]

The flow rate of the given fluid in the pipe is gotten as; 3/2 liters per minute

<h3>How to calculate the rate of flow?</h3>

We are told that a pipe fills 11/15 liters in 22/45 minutes.

Now, to get the flow rate of this pipe, we will use the formula;

Flow rate = Quantity of fluid/Time

Thus;

Flow rate = 11/15 ÷ 22/45

⇒ 11/15 * 45/22

⇒ 3/2 liters per minute

Answer: Translate triangle ABC so that point B lies on point D to confirm ∠B ≅ ∠D.

Step-by-step explanation: Since we already know that angle A is congruent to itself by the reflexive property, all we need is another pair of corresponding angles to be congruent according to the AA (angle-angle) similarity postulate. This postulate states that; If two corresponding angles of two or more triangles are congruent, the triangles are similar. So when we translate triangle ABC so that point ∠B lies on ∠D, we prove that these two angles are congruent.

I also got it right on the test. So... yeah.

hope this helps dood.

Answer:

  see attached

Step-by-step explanation:

Once the data is entered into a spreadsheet, it is convenient to sort the table by the input values. The relation is unchanged, but it may be easier to work with that way.

The table is shown below.
