3x+6y=5
-3x-3y=7

Solve the systems of equations

Answers

Answer 1

Answer:

[tex]x = -\frac{19}{3}, y = 4[/tex] or [tex](-\frac{19}{3}, 4)[/tex]

Step-by-step explanation:

Given the systems of linear equations, 3x + 6y = 5 and -3x - 3y = 7:

Equation 1: 3x + 6y = 5

Equation 2: -3x - 3y = 7

The best method to use for the given system is the process of elimination, since the coefficients of x in both equations have opposite signs.

Step 1: Add both equations:

3x + 6y = 5

-3x - 3y = 7

       3y = 12

Step 2: Divide both sides by 3:

[tex]\frac{3y}{3} = \frac{12}{3}[/tex]

y = 4

Step 3: Substitute the value of y into Equation 1:

3x + 6y = 5

3x + 6(4) = 5

3x + 24 = 5

Step 4: Subtract 24 from both sides:

3x + 24 - 24 = 5 - 24

3x = -19

Step 5: Divide both sides by 3:

[tex]\frac{3x}{3} = \frac{-19}{3}[/tex]

[tex]x = -\frac{19}{3}[/tex]

Verify the validity of x and y as solutions:

Verify whether the values for x and y satisfy both equations: [tex]x = -\frac{19}{3}, y = 4[/tex]

Equation 1:  3x + 6y = 5

[tex]3(-\frac{19}{3}) + 6(4) = 5[/tex]

-19 + 24 = 5

5 = 5 (True statement).

Equation 2:  -3x - 3y = 7

[tex]-3(-\frac{19}{3}) - 3(4) = 7[/tex]

19 - 12 = 7

7 = 7 (True statement).

Therefore, the solutions to the given systems of linear equations are: [tex]x = -\frac{19}{3}, y = 4[/tex], or [tex](-\frac{19}{3}, 4)[/tex].

x = -19/3, y = 4

3 1/2 divided by 2 3/5

Answers

Answer:

26/35

Step-by-step explanation:

1. First to divide the 3 1/2 by 2 3/5 you have to turn them both into improper fractions

First take 3 1/2. You have to multiply the whole number (3) by the denominator (2) and you would get 6. Then you would add then you add the product (6) to the numerator (1) and get 7.

You keep the denominator the same so the improper fraction is 7/2

Do the same thing to 2 3/5 and the improper fraction is 13/5

2. Now we can divide 13/5 by 7/2 using "keep, change, flip"

Keep: 13/5

Change: division to multiplcation

Flip: 7/2 to make 2/7

Your new equation is 13/5 × 2/7. Multiplcation is easy so you just have to multiply staight across: 13 × 2 and 5 × 7 giving you 26/35

If you divide 35 by 26 you will get 1.34 and a bunch of other numbers but I usually stop at two decimal places

What is geometrical progression series?

A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.

For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.

As per the given GP series,

3,15,75,375, 1,875​

The common ratio r = 15/3 = 5

First term a = 3

The nth term is given as a[tex]r^{n-1}[/tex]

Therefore,

The nth term will be as, 3 × [tex]5^{n-1}[/tex]..

Hence "The first term is 3 and the explicit rule for the given geometric sequence is 3 × [tex]5^{n-1}[/tex]".

A single triangle is 180 degrees.

As you can see. Triangle A, as it is shown in the bad drawing. It is an isosceles triangle because two sides are equal to one another, indicated with the lines. Angle A is given as 57. By the isosceles triangle theorem, Angle A equals to Angle B. Calculating the missing angle: 180 - 57 (given) - 57 (because of the isosceles triangle theorem type of thing. I forgot) = 66

You can see it is a verticle angle so angle C is equal to angle D, therefore angle D is 66.

Again it is an isosceles triangle so Angle F is 66. 180 - 66(angle D) - 66(angle F) = 48 = angle x

Angle A = 57 degrees. Given

Angle A = Angle B. isosceles triangle theorem

Angle B = 57 degrees. Substitute

Angle A + Angle B + Angle C = 180. Definition of Triangle (I forgot what it was called)

57 + 57 + Angle C = 180. Substitution

Angle C = 66. Subtraction

Angle C = Angle D. Verticle angle theorem.

Angle D = 66. Substitution

Angle F = Angle D. isosceles triangle theorem

Angle F = 66. Substitution

Angle D + Angle F + Angle X = 180. Definition of Triangle?

66 + 66 + Angle X = 180. Substitution

Angle X = 48. Subtraction

The product of 6 and a number is 38. Find the number

Answers

Answer:

n = 6 1/3

Step-by-step explanation:

"Product" means to multiply

Can be written as 6 x n = 38 or 6n = 38

6n = 38

6n/6 = 38/6

n = 6 2/6

n = 6 1/3

If the product of 6 and a number is 38 then the number 'x' is equal to 6.33.

Let's denote the unknown number as 'x'. According to the given information, the product of 6 and 'x' is equal to 38. We can express this mathematically as:

6x = 38

To find the value of 'x', we need to isolate it on one side of the equation. We can achieve this by dividing both sides of the equation by 6:

6x/6 = 38/6

Simplifying the equation, we have:

x = 6.33

Therefore, the number 'x' is equal to 6.33.

It's important to note that in this case, the number 'x' is not an integer but a decimal value. The equation 6x = 38 represents a proportional relationship, where 6 times the value of 'x' equals 38. By dividing both sides by 6, we solve for 'x' and determine that it is approximately 6.33.

Step-by-step explanation:

Given the systems of linear equations, y = 2x + 1 and y = 2x - 1:

Both equations in the system have the same slope, m = 2, thus forming parallel lines.  Since their lines are parallel from each other, then it means that their lines will never intersect.

Therefore, the given systems of linear equation is an inconsistent system that has no solution.
