Mathematics
1 answer:
kicyunya [14]3 years ago
8 0

Answer:

Step-by-step explanation:

Step 1:

Isolate x (1st Equation)

2x + 3y = 0

<u>      - 3y = -3y</u>

       2x = -3y

Step 2:

Divide both sides by 2

x = -3y/2

Step 3:

Replace the x from 8x with -3y/2 and Solve the equation

8(-3y/2) + 9y = 18

-12y + 9y = 18

-3y = 18

y = -6

Step 4:

Go back to the 1st equation and replace the y from 3y with -6. You are now solving for x. Solve the equation.
2x + 3(-6) = 0

2x - 18 = 0

<u>     + 18 = +18</u>

      2x = 18

x = 9

Step 5:

Write your final answer.

(x, y) = (9, -6)

An exterior angle of a regular polygon cannot have the measure Select one: a. 90 b. 120 c. 50 d. 40 e. 30
Otrada [13]

Answer:  c. 50

Step-by-step explanation:

1. By definition, when you add the exterior angles of a regular polygon, you obtain 360 degrees and the number of sides of that polygon can be calculated by dividing 360 degrees by the measure of the exterior angle of it.

2. As you know, the number of sides cannot be fractions, therefore, if you make the folllowing division:

360°/50°=36/5

You obtain a fraction.

3. Then, an exterior angle of a regular polygon cannot have the measure is 50°.

a Members of a soccer team raised $1530.50 to go to a tournament. They rented a bus for $1164.50 and budgeted $30.50 per player
Helen [10]

The number of players that can be taken to the tournament is 12 players.

The equation that can be used to represent the total amount spent by the soccer team is:

Total amount spent = cost of rented bus + (cost per meal x total number of players)

$1530.50 = $1164.50 + $30.50x

Where: x = total number of player

In order to determine the value of x, the following steps would be taken:

Combine similar terms

$1530.50 - $1164.50 = $30.50x

$366 = $30.50x

Divide both sides of the equation by 30.50

x = $366 / $30.50

x = 12 players

Question: (5x-8)/(45x^2--42x-48)
My name is Ann [436]

To solve this problem you must apply the proccedure shown below:

1. You have the folllowing expression given in the problem above:

(5x-8)/(45x^{2}-42x-48)

2. The first thing you must do is to factor the denominator, as following:

(5x-8)/3(3x+2)(5x-8)

3. Now, simplify it and apply the distributive property in the denominator:

1/3(3x+2)=1/9x+6

The answer is: 1/9x+6
