Answer:

1. a = 2

2. x = 12

3. w = 2

Step-by-step explanation:

1. ok so 2a/5 we would want to separate it to 2/5 and a/5

2/5 x a/5 = 2a/5

next we want to subtract 2/5 from 8/10

8/10 - 2/5 or 8/10 - 4/10 = 4/10

now you have a/5 and 4/10

a/5 = 4/10

now you multiply each side by 5

a/5 x 5 = a

4/10 x 5 = 20/10 or 2

a = 2

2. ok so the x is kinda on it's own for this one but we still wan to get the x and the other numbers on opposite sides

1/16x + 1/4 - 1/4 = 1/16x

1/2 + 1/4 = 3/4

now we do that same last step

1/16x / 1/16 = x

3/4 / 1/16 = 12

x = 12

3. ill do one more and if you need more help just tell me

for this on we have the w on both sides so we have to get the variable(w) and the numbers on opposite sides

2w - 2 + 2 = 2w

1/2w + 7 - 1/2w = 7

2w + 1/2w = 5/2w or 2 1/2w

7 - 2 = 5

now we have to divide each side by 5/12 or 2 1/2

5/2w / 5/2 = w

5 / 5/2 = 2

w = 2

What is the value of (-7 + 3i) - (2-6i)?

Doss [256]

Answer:

9 (i - 1)

Step-by-step explanation:

Simplify the following:

-7 + 3 i - (-6 i + 2)

-(2 - 6 i) = -2 + 6 i:

6 i - 2 - 7 + 3 i

-2 + 6 i - 7 + 3 i = (6 i + 3 i) + (-2 - 7) = -9 + 9 i:

9 i - 9

Factor 9 out of 9 i - 9 giving 9 (i - 1):

Answer: 9 (i - 1)

A polygon has vertices whose coordinates are A(1, 4), B(4, -1), C(-1, -4), and D(-4, 1). Use the midpoint formula to determine w

Alenkinab [10]

Answer:

The diagonals of the polygon ABCD bisect each other

Step-by-step explanation:

The given vertices of the polygon are;

A(1, 4), B(4, -1), C(-1, -4), and D(-4, 1)

Given that the vertices of the polygon in clockwise order from the top left corner are ABCD, we have the diagonals as AC and DB

By the midpoint formula, we have;

$(x_m , \ y_m) = \left (\dfrac{x_1 + x_2}{2} , \ \dfrac{y_1 + y_2}{2} \right )$

Where;

$(x_m , \ y_m)$ = The midpoint coordinates

Therefore, the midpoint of diagonal AC = $\left (\dfrac{1 + (-1)}{2} , \ \dfrac{4 + (-4)}{2} \right ) = (0, 0)$

The midpoint of diagonal DB = $\left (\dfrac{(-4) +4}{2} , \ \dfrac{1 + (-1)}{2} \right ) = (0, 0)$

Therefore, given that the coordinates of the location of the midpoint of the diagonals AC and DB is the same, the diagonals bisect each other

Each diagonal passes through the midpoint of the other diagonal.
