Plss need Help ASAP! :(​

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:

c. 2(x-1)(x-4)

Step-by-step explanation:

c. 2(x-1)(x-4)

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

Answer:

28/8=3.50

Step-by-step explanation:3.50 per pear.

Answer:

b. -1

Step-by-step explanation:

9=4a+13

-13    -13

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

-4=4a

4a/-4

a=-1

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:

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:

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.

Because he bought 1 yardstick and r rulers so to find the total number you need to add both numbers together.

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

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]
