Answer:

-45x - 18

Step-by-step explanation:

distributive property

Answer:

x = 18/45 (or, in a decimal, 0.4). Someone correct me if I'm wrong. :)

Step-by-step explanation:

We have to use the distributive property here. That means that you multiply -5x by 9 and -2 by 9. So...

9*-5x = -45x

9*-2 = -18

-45x = -18

Now, divide both sides by 45...

-45x/45 = -18/45

x = 18/45 should be the answer.

Solve the equation for b 5= 3/2 (3) + b

Answers

Answer:

The answer is b = 1/2

Step-by-step explanation:

1) Use this rule: a/b × c = ac/b.

[tex]5 = \frac{3 \times 3}{2} + b[/tex]

2) Simplify 3 × 3 to 9.

[tex]5 = \frac{9}{2} + b[/tex]

3) Subtract 9/2 from both sides.

[tex]5 - \frac{9}{2} = b[/tex]

4) Simplify 5 - 9/2 to 1/2.

[tex] \frac{1}{2} = b[/tex]

5) Switch sides.

[tex]b = \frac{1}{2} [/tex]

Therefor, the answer is b = 1/2.

What would be the slope of a line that is perpendicular to the linear equation y = (-2/3)x +5?

Answers

Answer: The slope of a perpendicular line will be m = 3/2. To find the perpendicular gradient take the negative inverse of the original gradient.

Step-by-step explanation:

The slope of a perpendicular line will be m = 3/2. To find the perpendicular gradient take the negative inverse of the original gradient.

By 'negative inverse' I mean change the sign and switch the numerator and denominator (the top and bottom of the fraction).

The original gradient there is m = - 2/3. Remember the line equation: y = mx + c.

To gain the perpendicular gradient change the - to +, move the 3 to the top and the 2 to the bottom. Now m = + 3 / 2 = 3/2

Answers

Answer:

x= −1 /2 y+4

Step-by-step explanation:

Let's solve for x.

2x+y=2(6−2)

Step 1: Add -y to both sides.

2x+y+−y=8+−y

2x=−y+8

Step 2: Divide both sides by 2.

2x /2= −y+8 /2 x= −1 /2 y+4

A -1/2
B 0
C 1/2

Answers

Use the first and lay set of x,y values.

Rate of change is change in y/ change in x:

7-10 / 5- -1 = -3/6 = -1/2

The answer is A.-1/2

A.-1/2 is the answer due to the fact that the rate of change is y/x. The rate at which the y values are changing is -1, and the rate at which the d values are changing is +2. Put them together, -1/2. Hope this helps

then you plus 5 to 27

u then have 4y=32

then divide 32 by 4

so you will get y=8

the answer is y is equal to 5 because when you move the -5 over to the other side it becomes 27+5 =32 now the 13y-9y=5y

Question 1
Tell whether the angles are adjacent or vertical. Then find the value of x.

Answers

Step-by-step explanation:

The angles are vertical because they are opposite to each other

75 = 4x -25 vertical angles

100 = 4x

x= 25° Algebra

Answer:

X = 25 degrees

Definitions:

Vertical: Opposite angles/angles that share a common side.

Adjacent: Congruent meaning same measure.

Step-by-step explanation:

This equation would be vertical because they are opposite from eachother:

Our equation would look like this:

75 = 4x - 25

Then add 75 and 25 to get 100:

75 + 25 = 100

Now our equation would look like this:

100 = 4x

Lastly, divide 100 with 4:

100 ÷ 4 = 100

Side note: 25 x 4 = 100

Your answer would be x = 25 degrees.

Answer:

Step-by-step explanation:

She walked 12 miles. Then she walked 1/4 that distance. "That distance" is 12 miles.

That means she walked 12 miles plus 1/4 of 12 miles.

She walked

12 + 1/4 * 12

You can factor out 12 from the expression above, and write it as

12(1 + 1/4)

Now you can do the addition in parentheses.

12(1 + 1/4) = 12(4/4 + 1/4) = 12(5/4)

Answer:

C, D, F

Answer:

12 + 1/4 x 12, 12 x 5/4, and 12 (1 + 1/4)

Step-by-step explanation:

To solve this, you need to add 1/4 of 12 to 12. 1/4 of 12 is 3, and 12 + 3 is 15. All of these equations are equal to 15, therefore they are all correct.

1/4 x 12 = 3 + 12 = 15

12 x 5/4 = 60/4 = 15

1 + 1/4 = 5/4

5/4 x 12 = 60/4 = 15
