How many solutions does the following equation have?
13x - 8 + 7x – 2 = 11+ 6x -- 14x – 5

Answer:

100

Step-by-step explanation:

│an − L│< ε

│(1 − 1/n) − 1│< 1/100

│-1/n│< 1/100

1/n < 1/100

n > 100

Answer:

10

Step-by-step explanation:

you can cross multiply.

[tex]\frac{12}{15}=\frac{8}{k}[/tex]

after you cross multiply:

12k=120

k=10

Answer:

1: m=2

2: g=7

3: y=13

4: a=-27

5: x=15

6: w=-18

Answer:

1. m = -2  

2. g = 7  

3. y = 13      

4. a = -36  

5. x = 15

6.  w = -18                                                                                                                                            

Step-by-step explanation:

1. Make the constant to the right-hand side and change its sign

a = 10 - 12

Calculate the difference a = -2

Solution

a = -2

2. Move variable to the left-hand side and change its sign

-g - 2 = - 9

Move constant to the right-hand side and change its sign

-g = -9 + 2

Calculate the sum

-g = -7

Change the signs on both sides of the equation

g = 7

Solution

g = 7

3. Divide both sides of the equation by - 7

-7y ÷ (-7) = -91 ÷(-7)

Any expression divided by itself equals 1

y = 91 ÷ (-7)

Divide two negatives equals a positive: (-) ÷(-)=(+)

y = 91 ÷ 7

Calculate the quotient

y = 13

Solution

y = 13

4. Multiply both sides of the equation by 9

9 x a/9 = 9 x (-4)

Reduce the number with the greatest common factor 9

a = 9 x (-4)

Multiply a positive and a negative equals a negative: (+)x(-)=(-)

a = -9 x 4

Multiply the numbers

a = -36

Solution

a = -36

5. Multiply both sides of the equation by 3/2

3/2 × 2/3x =  3/2 × 10

Reduce the numbers with the greatest common factor 3

1/2 × 2x = 3/2 × 10

Reduce the numbers with the greatest common factor 2

x = 3/2 × 10

Reduce the numbers with the greatest common factor 2

x = 3 x 5

Multiply the numbers

x = 15

Solution

x = 15

6. Multiply both sides of the equation by 9/4

9/4 x 4/9w = 9/4 x (-8)

Reduce the numbers with the greatest common factor 9

1/4 x 4w = 9/4 x (-8)

Reduce the numbers with the greatest common factor 4

w = 9/4 x (-8)

multiplying a positive and a negative equals and negative: (+)x(-)=(-)

w = -9/4 x 8

Reduce the numbers with the greatest common factor 4

w = -9 x 2

Multiply the numbers

w = -18

Solution

w = -18

Step-by-step explanation:

Every seventh and fifth day, both numbers are prime, 5 x 7 = 35, so 35 days after October 24th is November 29th because October has 30 days.

Given expression:

             A  = [tex]\frac{1}{2}(b_{1} + b_{2} )[/tex]

Solve for b₁;

  Solution:

This is a subject of the formula problem.

  Given expression:

               A  = [tex]\frac{1}{2}(b_{1} + b_{2} )[/tex]

First, multiply both sides by 2;

          2 x A  = 2 x [tex]\frac{1}{2}(b_{1} + b_{2} )[/tex]  

              2A  = b₁  + b₂

Then subtract b₂ from both sides;

           2A - b₂ = b₁ + b₂ - b₂

                 b₁ = 2A - b₂

The solution is   b₁ = 2A - b₂

Answer:

No Gym A cost $30 more dollars than Gym B.

Answer:

$38,640.00

Step-by-step explanation:

We know that Catrina earns $19.32 an hour. We also know she works 40 hours a week. So first, let's multiply 19.32 by 40 to see how much she makes a week.

19.32 × 40 = 772.80

Because of this, we now know that Catrina makes $772.80 a week. There are 52 weeks in a year. However, since she takes 2 weeks of vacation, we need to take off 2 weeks in the year. This leaves us with 50.

Finally, we multiply 772.80 and 50 to find her annual earnings:

772.80 × 50 = 38640

Therefore, her annual earnings will be $38,640.00.

Answer:

$898

Step-by-step explanation:

Based on Joey's debt-to-income ratio, the maximum monthly rent payment he can make and still maintain the DTI ratio is b. $898.

Joey has a DTI ratio of 36% which means that his maximum debt payment should be 36% of his income. This amount would be:

= DTI x monthly income

= 36% x 3,600

= $1,296

This can be found as:

= Maximum monthly debt payment - Car payment - Credit card payment

= 1,296 - 178 - 220

= $898

In conclusion, option B is correct.

If there are 2 or more right angles in a triangle, it is impossible to connect without a fourth side, making it a square. There can only be 1 right angle in a triangle

Answer:

There can Only be 1 Right angle in a Triangle!

Step-by-step explanation:

Triangles have 180 degrees in total, If You had Two Right Angles, Then it would equal 180, since there is three angles,three sides and etc on a triangle that won't work. In a Triangle you could have 1 right angle and Two 45 degree angles to get your total of 180 degrees and a complete Triangle!!

Step-by-step explanation:

A geometric figure has rotational symmetry if the figure appears unchanged after a rotation about a point by an angle that is between 0° and 360°. 0° and 360° are excluded since they represent the original position, nothing new happens. The angles of rotational symmetry will be factors of 360.

Answer:

C. -11

Step-by-step explanation:

f(x) = -2x - 5

Plug the 3 in for x

f(3) = -2(3) - 5

Multiply the -2 and 3

f(3) = -6 - 5

Subtract 5 from -6

f(3) = -11

Answer: C -11

Step-by-step explanation:

Its asking you to solve for f(x) which is Y

Y=-2x-5

X is 3

so replace -2x with 3 but only the x

you should get -23 not negative 23 its more of 2 times 3

then multiply -2 by 3 and get -6

add -6 and -5 to get -11
