1. 2a + 3a = 5a

2. 4x - 2x = 2x

3. x * x = x sq or x^2

4. 7x / x (x and x cancels out from the numerator and denominator, so we are left with 7 / 1 or 7) = 7

5. 5x + 3x - 4x = 4x

b. 4a^2 + a^2 + 2a^2 = 7a^2

b. 15x^2 - 5x^2 = 10x^2

b. a^2 * a * a^2 = a^5

b. 4ab / 2ab = 2

b. 4x^2 - x^2 - x^2 = 2x^2

Hope you understood the above. If you need any help I will be make sure to help you.

Solve the following 3 × 3 system. Enter the coordinates of the solution below.
defon

9514 1404 393

Answer:

  (x, y, z) = (-1, 0, -3)

Step-by-step explanation:

We notice that the coefficients of z are such that elimination of the z term from the equations is made easy.

Adding equations 1 and 2:

  (2x -3y -2z) +(x +3y +2z) = (4) +(-7)

  3x = -3

  x = -1

Adding equations 2 and 3:

  (x +3y +2z) +(-4x -4y -2z) = (-7) +(10)

  -3x -y = 3

Substituting for x, we get ...

  (-3)(-1) -y = 3

 0 = y . . . . . . . . . . . add y-3 to both sides

Then z can be found from any equation. Substituting for x and y in the second equation gives ...

  -1 +2z = -7

  2z = -6 . . . . . add 1

  z = -3 . . . . . .divide by 2

The solution is (x, y, z) = (-1, 0, -3).

20 is what percent of 160
stira [4]
In this problem WP means what percent

20 = WP  X 160

solve for WP, by dividing both sides by 160

and you get:

0.125 = WP

Change your decimal into a percent by multiplying by 100%

12.5% is your result.
