12 - 3x = -6x
I’m confused on how to solve for X if they are on both sides

Answers

Answer 1

Answer:

x =-4

Step-by-step explanation:

[tex]12 - 3x = -6x[/tex]

Step 1 ; Collect like terms . (put the numbers with variables on one side of the equation and ordinary numbers on the other side )

[tex]12 =-6x+3x[/tex]

Note ; When a number is crossing over an equality sign ; the sign will always change

Step 2 ;

Simplify

[tex]-6x +3x =-3x\\\\ 12=-3x[/tex]

Step 3 ; Divide both sides of the equation by -3

[tex]\frac{12}{-3} = \frac{-3x}{-3} \\\\-4 = x[/tex]

Switch sides

[tex]x =-4[/tex]

Rewrite the equation for x, and express its value in terms of a. 3/a x - 4 = 20

Answers

For this case, we must clear variable "x" from the given equation, expressed in terms of "a".

We have:

3/a x-4=20

By clearing "x" we have:

Adding 4 to both sides of the equation:

3/a x = 20 + 4

Multiplying by a/3 on both sides of the equation:

x=24a/3

x=8a

So, x=8a

-80

solve by using BODMAS rule

Answer: -80

First step is to calculate everything inside the brackets = [3× (-2) -10] = [(-6) - 10] = [(-16)] then we now multiply the number outside the brackets with the number inside the brackets which = 5[-16] = -80.

Which two ratios represent quantities that are proportional?

A 22/33 and 14/21
B 48/60 and 35/42
C 25/28 and 5/7
D 16/13 and 13/16

Please help

Answers

A: 22/3 and 14/21 = 1/3

The two ratios represent proportional quantities is A: 22/3 and 14/21 = 1/3

When do two ratios form a proportion?

Two ratios form a proportion if the simplified form of both ratios comes out as the same ratio. Suppose that we've got two quantities with measurements as 'a' and 'b' Then, their ratio(ratio of a to b) a:b

We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained. Remember that the ratio should always be taken of quantities with the same unit of measurement. Also, the ratio is a unitless(no units) quantity.

A.) 22/33 and 14/21

Here. the two ratios represent quantities that are proportional to 1/3.

B.) 48/60 and 35/42

Here. the two ratios represent quantities that are not proportional.

C.) 25/28 and 5/7

Here. the two ratios represent quantities that are not proportional.

D.) 16/13 and 13/16

Here. the two ratios represent quantities that are not proportional.

Hence, The two ratios represent proportional quantities is A: 22/3 and 14/21 = 1/3

Write an equation that would model the tile pattern above where x represents the figure number and y represents the number of tiles

Answers

Just add 2 to figure 2 and keep adding
For figure zero subtract 2

The equation that would model the tile pattern above where x represents the figure number and y represents the number of tiles is y = 2x + 5.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The three figures are shown in the picture.

After analysis:

2(3) + 1  = 7

2(4) + 1  = 9

2(5) + 1  = 11

The standard form:

y = 2(x+2) + 1

y = 2x + 4 + 1

y = 2x + 5

Thus, the equation that would model the tile pattern above where x represents the figure number and y represents the number of tiles is y = 2x + 5.

An interior designer charges $100 to visit a site, plus $55 to design each room. Identify a function that represents the total amount he charges for designing a certain number of rooms. What is the value of the function for an input of 6, and what does it represent?

Answers

Answer:

C(r) = 100 + 55r

C(6) = $430

Step-by-step explanation:

Fixed charges = $100

Charges per room = $55

A. function that represents the total amount he charges for designing a certain number of rooms.

Let

r = number of rooms

C = Total amount charged

C(r) = 100 + 55r

The function is C(r) = 100 + 55r

B. What is the value of the function for an input of 6, and what does it represent

C(r) = 100 + 55r

When r = 6

C(6) = 100 + 55 * 6

= 100 + 330

= 430

C(6) = $430

This means that the amount charged for 6 rooms is $430

Simplify your answer. Type an exact answer...

Answers

Answer:

The answer is 10 units

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A(7-5); B(7,5)

The distance between them is

[tex]d = \sqrt{ ({7 - 7})^{2} + ({ - 5 - 5})^{2} } \\ = \sqrt{ {0}^{2} + ( { - 10})^{2} } \\ = \sqrt{100} [/tex]

We have the final answer as

The student to faculty ratio at a small college is 17:3 the total number of students and faculty is 740. How many faculty members are there at the college?

Answers

Answer:

111

Step-by-step explanation:

It is given that the student to faculty ratio at a small college is 17:3.

Let number of students and faculty members are 17x and 3x respectively.

It is given that total number of students and faculty is 740.

[tex]17x+3x=740[/tex]

[tex]20x=740[/tex]

Divide both sides by 20.

[tex]x=37[/tex]

Number of student [tex]=17\times 37=629[/tex]
