-13    -13

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

-4=4a

4a/-4

a=-1

Answer:

7.

Step-by-step explanation:

9y+12=75

subtract 12 from 75

divide by 9y

Answer:

D

Step-by-step explanation:

it is D because you always want x to be a lone fraction and that would be the first step im 99% sure unless someone can correct me :)

Answer:

d) subtract 15 from both sides

Step-by-step explanation:

Process of elimination:

a) 2.5 and x are being multiplied, not subtracted, so (a) is wrong right off the bat.

b) you may divide 2.5 by both sides, but you want to get "x" on one side first. So you would do (b) first either.

c) to get rid of 15, which we need to somehow, we need to do the opposite operation than the one in the equation. 15 is +15, not negative, and so you would need to subtract to get rid of 15. This is why (c) is also wrong.

That leaves us, with (d), because you need to subtract 15 to isolate "x".

Answer:

False

Step-by-step explanation:

Answer: False

Step-by-step explanation: Absolute value is the number of whole numbers the number is away from zero. So it can only be positive because you cannot have a number negative spaces away from zero

Sum of two angles that are supplementary = 180°

Then :-

[tex]3x - 2 + 2x+ 7 = 180[/tex]

[tex]5x + 5 = 180[/tex]

[tex]5x = 180 - 5[/tex]

[tex]5x = 180 - 5[/tex]

[tex]5x = 175[/tex]

[tex]x = \frac{175}{5} [/tex]

[tex]x = 35[/tex]

Which means :-

The measure of the larger angle :-

= 35 × 3 - 2

= 105 - 2

= 103°

The measure of the smaller angle :-

= 2 × 35 + 7

= 70 + 7

Therefore , the value of x = 35 and the measure of the smaller angle = 77° .

Answer:

37.5%

Step-by-step explanation:

24÷64=0.375

with percents, you have to move the decimal 2 spaces back

so that equals 37.5%

Answer:

75 minutes

Step-by-step explanation:

if it takes 30 minutes to paint 2/5 of the room, then it must take 15 minutes to paint 1/5 of the room.

15 * 5 = 75 minutes or 5/4 hours

Answer:

Step-by-step explanation:

Tax = 8% of 23

      = [tex]\frac{8}{100}*23[/tex]

      = [tex]\frac{184}{100}[/tex]

      = $ 1.84

Answer

The answer is $1.84

Step-by-step explanation

The formula for calculating the sales tax on a good or service is: selling price x sales tax rate, and when calculating the total cost of a purchase, the formula is: total sale amount = selling price + sales tax.

Answer:

The amount of fencing Madisyn needs is approximately 20.77 m

Step-by-step explanation:

The coordinates of the vertices of the triangular garden are;

A(0, 6), B(6, 5), and C(5, -1)

The length of the sides of the triangle can be found through the given coordinates and the distance between coordinates formula presented as follows;

[tex]Distance \ between \ points \ given \ the \ coordinates = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]

Therefore, the length of AB is [tex]\sqrt{\left (5-6 \right )^{2}+\left (6-0 \right )^{2}} = \sqrt{37}[/tex]

The length of BC is [tex]\sqrt{\left (5-(-1) \right )^{2}+\left (6-5 \right )^{2}} = \sqrt{37}[/tex]

The length of AC is [tex]\sqrt{\left (6-(-1) \right )^{2}+\left (0-5 \right )^{2}} = \sqrt{74}[/tex]

Therefore;

The amount of fencing Madisyn needs = The length of the sides of the triangular garden

The length of the sides of the triangular garden =  The length of AB +  The length of BC + The length of AC

The length of the sides of the triangular garden = √37 + √37 + √74 ≈ 20.77 m.

The amount of fencing Madisyn needs ≈ 20.77 m.

Answer:

Subtract 3

Step-by-step explanation:

Each time the following number decreases by 3

Answer:

Because it is 2 of the same number.

Step-by-step explanation:

Answer:

I believe this is because a square is symmetrical and even so are numbers we multiply are the same number. And because there are two of the same number.

Answer:

(w + 3) [7w²  - 3]

Step-by-step explanation:

Given expression:

    7w²(w + 3) - 3(w + 3);

 Now rewriting the equation by factoring out (w+ 3);

 Solution:

   7w²(w + 3) - 3(w + 3);

   = (w + 3) [7w²  - 3]

The solution is (w + 3) [7w²  - 3]

Answer:

3/5 because you find what goes into each and simplify. 9/15 each divided by 3. 9/3=3 15/3=5 so 3/5 is your answer.

Answer:

x=15

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

9x−38+4x+23=180

9x+−38+4x+23=180

(9x+4x)+(−38+23)=180(Combine Like Terms)

13x+−15=180

13x−15=180

Step 2: Add 15 to both sides.

13x−15+15=180+15

13x=195

Step 3: Divide both sides by 13.

13x/13=195/13

Answer:

15

Step-by-step explanation:

9x-38+4+23=180

13x-15=180

13x=195

x=15
