find the solution for X
3x - 5 = 7x + 11

Answers

Answer 1

Answer:

x=-4

Step-by-step explanation:

3x-5=7x+11    Add like terms

   +5     +5

3x=7x+16       Do it again...

-7x   -7x

-4x=16        Now divide

x=-4

Answer 2

Answer:

The answer is x=-4

Step-by-step explanation:

3x-5=7x+11

1) you have to move the number that has a variable with it onto one side(3x and +7x) and the numbers that do not have a variable move them onto the other side (-5 and +11),but if you move them you have to change the sign like the underlined numbers below

3x-7x=5+11

2) you have to subtract 3x and-7x which it equals  -4x and then you have to add 5 and 11 which it equals 16

Equation now -4x=16

3) you have to divide -4x into -4x and also divide -4x into 16 which you will get x=-4

Hope it helps out! :)

You buy 4 balloons and 2 banners for $8. Your friend buys 6 balloons and 1 banner for $8.


Each balloon costs ?$

and each banner costs ?$

Answers

Answer:

Each balloon costs $1

Each banner costs $2

Step-by-step explanation:

First of all, let's write down the equation from this problem.

Let "y" be the cost of the ballon, and let "x" be the cost of a banner. Then the following is true from the question...

4y + 2x = 8

6y + x = 8

Now since both of them are equal to 8 both of them are equal to each other, and so we can get the following equation...

4y + 2x = 6y + x

2x - x = 6y - 4y

x = 2y

Now if we substitute 2y instead of x in one of the previous equations we will obtain...

6y + x = 8

6y + 2y = 8

8y = 8

y = 1

From the equation x = 2y we know that...

x = 2y

x = 2(1)

x = 2

A bus increases its position at a constant velocity for 12 s, and then it stops for 6 s.

Which option lists a true statement about how a distance-time graph would represent this motion?

A) The slope of the graph would be negative and constant for 12 s; then, the slope would be constant for 6 s because the slope represents velocity.

B) The slope of the graph would be positive and constant for 12 s; then, the slope would be 0 for 6 s because the slope represents velocity.

C) The slope of the graph would be positive and increasing for 12 s; then, the slope would be constant for 6 s because the slope represents velocity.

D) The slope of the graph would be negative and constant for 12 s; then, the slope would be 0 for 6 s because the slope represents the passing of time.

Answers

Answer:

D

Step-by-step explanation:

The slope of the graph would be negative and constant for 12 s; then, the slope would be 0 for 6 s because the slope represents the passing of time. Therefore, option D is the correct answer.

What is a constant velocity?

Velocity gives us information about the rate of change of your position, meaning how fast your position is changing per unit time.

Given that, a bus increases its position at a constant velocity for 12 s, and then it stops for 6 s.

Here, rate of change is 12/6 = 2 s

Therefore, option D is the correct answer.

You are taking a quiz that has 9 multiple-choice questions. If each question has 3 possible answers, how many different ways are there to answer the test?

Answers

Answer:

19 683

Step-by-step explanation:

Think of it as s lock..

A normal combination lock usually have 3 scrollwheels with 10 different positions in them.. (0 1 2 3 4 5 6 7 8 9)

The smallest number you can make is 000

and the biggest is 999

therefore there are a total number of 1000 possible combinations. (001, 002, 003 ... 134, 135, 136 ... 876, 877)

I think you get it.

Simply: 10 ^ 3 = 1000

In your question we have 9 "scroll wheels" with 3 "different positions" in them

So we simply do: 3 ^ 9 = 19 683

Step-by-step explanation:

m║n   ⇒   (9x + 2)° = 74°       {Corresponding Angles}

(9x)° = 72°

 x = 8

Angles: angle corresponding to angle (5x-1)°, angle 74° and angle 2 add to 180° (straight angle)

(5×8 - 1)° + 74° + m∠2 = 180°

39° + 74° + m∠2 = 180°

113° + m∠2 = 180°

m∠2 = 180° - 113°

m∠2 = 67°

Answers

(y+10)(y-4)

Explanation:
In order to solve you must set the equation to 0. Meaning you subtract 49 from 9 to get the original equation to now be y^2+6y-40.
You then set that equation (y^2+6y-40) to zero in order to factor it out.
To do this, you have to find two numbers that multiply to make -40 but add to make 6, which is where you get 10 and -4.
