Answer:

(P-21)/2=w

Step-by-step explanation:

P = 21 + 2w

Subtract 21 from both sides:

P - 21 = 21 + 2w -21

Simplify:

P - 21 = 2w

Divide both sides by 2:

(P - 21)/2 = 2w÷2

Simplify:

(P-21)/2=w

Answer:

w = 1/2p -21/2

Step-by-step explanation:

P = 21 +2w.

-21   -21

P - 21 = 2w

/2        /2

1/2p - 21/2 = w

Hope this helps!

How do you tell if it's possible to make a triangle out of these side lengths?<br> PLZ HELP!!!!!
Nastasia [14]

Answer:

A

Step-by-step explanation:

square root of 73 is about 8.5

square root of 10 is about 3. multiply by 3, you get 9.

square root of 7 is about 2.6. multiply by 5, you get 13.

when determining if you can make a triangle, if all variants of two sides can add up to be greater than the third side, you can make the triangle. so 8.5+9 > 13; 13+9 > 8.5; 13+8.5 > 9. this means it can make a triangle and all you have to do is order the sides.

8.5 is smallest which corresponds to angle c because it's opposite. 9 goes to angle a, then finally 13 goes to angle b. thus, angles c, a, b is the order.

side note: the smallest side length will always correspond with the smallest angle.

hope this helps :)

Simplify the linear expression
vekshin1

Answer:

\huge\boxed{-\frac{7}{8}a - \frac{1}{6}}

Step-by-step explanation:

This question utilizes combining like terms and common denominators. First you have to convert both terms including "a" to have a denominator of 8. You would do this by multiplying both the numerator, and the denominator by the same value. This value in the case of -\frac{1}{4} a would be 2, and in the case of \frac{2}{3} the value would be 2. This would result in the equation: -\frac{5}{8}a+\frac{4}{6}-\frac{2}{8}a-\frac{5}{6}. Then simply combine like terms to get your final answer.

  • All angles in a triangle add up to 180°

Step-by-step explanation:

<u>Step 1: Set up Equation</u>

x + (x + 65) + 25 = 180

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Combine like terms:                     2x + 90 = 180
  2. Isolate <em>x</em> term:                               2x = 90
  3. Isolate <em>x</em>:                                        x = 45

What’s the equation of the blue line?
victus00 [196]

Uee two points on the line to find the slope.

(-1,2) and (1,-4)

Slope = change in y over change in x;

Slope = (-4  - 2)/ (1 - -1) = (-6/2) = -3/1 = -3

The y intercept is y value where the blue line crosses the y axis, which is at -1

The equation would be y = -3x-1
