Answer:

[tex]x=\frac{-3d-9}{k-d}[/tex]

Step-by-step explanation:

Step 1: Write out equation

d(-3 + x) = kx + 9

Step 2: Distribute

-3d + dx = kx + 9

Step 3: Subtract dx on both sides

-3d = kx - dx + 9

Step 4: Subtract 9 on both sides

-3d - 9 = kx - dx

Step 5: Factor

-3d - 9 = x(k - d)

Step 6: Divide both sides by k - d

[tex]x=\frac{-3d-9}{k-d}[/tex]

Answer:

Step-by-step explanation:

Step 1: Write out equation

d(-3 + x) = kx + 9

Step 2: Distribute

-3d + dx = kx + 9

Step 3: Subtract dx on both sides

-3d = kx - dx + 9

Step 4: Subtract 9 on both sides

-3d - 9 = kx - dx

Step 5: Factor

-3d - 9 = x(k - d)

Step 6: Divide both sides by k - d

What are the coefficients in this expression? 2x +9y+(-4) Select all that apply.
A 2
B 9
C 9y
D 2x​

Answers

A) 2 and B) 9
Coefficients are the numbers in front of a variable. The x and y wouldn’t be considered coefficients.

Answer: A and B

Step-by-step explanation:

Coefficient is the number or term that came before a variable.

If you can't understand this, I will provide some examples.

Coefficient in 3x is 3, 3 came before x which is a variable

-------------------------------------------------------------------

2x + 9y + (-4)

2x: coefficient is 2

9y: coefficient is 9

-4: no coefficient, it is just a constant

What is the solution to
-(6x+8)= 4(17 – x)?

Answers

Answer:

x=30

Step-by-step explanation:

Simplifying

6x + 8 = 4(x + 17)

Reorder the terms:

8 + 6x = 4(x + 17)

Reorder the terms:

8 + 6x = 4(17 + x)

8 + 6x = (17 * 4 + x * 4)

8 + 6x = (68 + 4x)

Solving

8 + 6x = 68 + 4x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4x' to each side of the equation.

8 + 6x + -4x = 68 + 4x + -4x

Combine like terms: 6x + -4x = 2x

8 + 2x = 68 + 4x + -4x

Combine like terms: 4x + -4x = 0

8 + 2x = 68 + 0

8 + 2x = 68

Add '-8' to each side of the equation.

8 + -8 + 2x = 68 + -8

Combine like terms: 8 + -8 = 0

0 + 2x = 68 + -8

2x = 68 + -8

Combine like terms: 68 + -8 = 60

2x = 60

Divide each side by '2'.

x = 30

Simplifying

x = 30

The solution to
-(6x+8)= 4(17 – x)? Is x=30

I know the answer is .78, but don’t understand why? .9-.6X.2

Answers

0.6 x 0.2 = 12 and .9 - .12 = .78

It may be confusing because the decimals aren’t like whole numbers.

Step-by-step explanation:

When you multiply 0.6 and 0.2, you do not get 1.2. Rather, the product would be 0.12.

We have the equation [tex]0.9-(0.6)(0.2)[/tex]

To show you what is happening, lets convert these numbers into fractions

This would give us [tex]\frac{9}{10} -(\frac{6}{10})(\frac{2}{10})[/tex]

Recall that when you multiply two fractions, you multiply the numerators and denominators separately. Doing so gives us

[tex]\frac{9}{10} -\frac{6*2}{10*10}[/tex]

Which then becomes

[tex]\frac{9}{10} -\frac{12}{100}[/tex]

The last thing we need to do is to create a common denominator

[tex]\frac{90}{100}-\frac{12}{100}=\frac{78}{100} =0.78[/tex]

Another way to see what is happening is by thinking about the numbers in scientific notation. Doing so would give us

[tex]9*10^{-1}-(6*10^{-1})(2*10^{-1})[/tex]

Once we multiply these terms, we get

[tex]9*10^{-1}-6*10^{-1}*2*10^{-1}\\\\9*10^{-1}-12*10^{-2}[/tex]

Now we can convert these numbers into decimals to get

[tex]0.9-0.12=0.78[/tex]

answer for this

Answers

Answer:

x= -12

Step-by-step explanation:

3(x+7)+6= -9

3x+21+6= -9

subtract 6 from both sides that gives you your equation that you can work with.

3x+21= -15

then subtract 21 from both sides that gives you

3x/3 = -36/3

the 3 cancels out and leaves you with -36 divided by 3

your answer is -12

Simplify these ratios.
(a) 1.8 kg : 600 grams
(b)
1 hour 20 minutes : 30 minutes

Answers

Answer:

a) 3 :1

b)8 : 3

Step-by-step explanation:

When finding ratio's, both should be in same units.

1.8 kg = 1.8 * 1000

         = 1800.0 grams

1.8 : 600 = 1800 : 600 = 18 : 6

              = 3 : 1

b) 1 hour  20 minutes = 60 + 20 = 80 minutes

1 hour  20 minutes : 30 minutes = 80 : 30

                                                     = 8 :  3

Answer:

a. 3grams : 1gram  b. 8 minutes : 3 minutes

Step-by-step explanation:

1.8kg is the same as 1800 grams.

1800:600 is the same as 3:1.

1 hour 20 minutes is the same as 80 minutes.

80:30 is the same as 8:3.

Answer: 3x + 3y - 13xy
Move the numbers so that the ones with the same variable can be together :> ( examples of variables: x,y,xy)
4x - x + 5y - 2y - 13xy
You can only do the math if the those numbers are the same example: 4x - x = 3x they both have variable so u can subtract them ( remember x = 1x a variable by itself has a invisible 1 next to it). 5y - 2y = 3y.
-13xy is the only one with the variable xy so we gotta just leave it alone
This leads to our answer:
3x + 3y - 13xy
