Answer: x = 75/2 = 37.5

Step by Step:

Solve for x:

2 x - 16 = 59

Hint: | Isolate terms with x to the left hand side.

Add 16 to both sides:

2 x + (16 - 16) = 16 + 59

Hint: | Look for the difference of two identical terms.

16 - 16 = 0:

2 x = 59 + 16

Hint: | Evaluate 59 + 16.

59 + 16 = 75:

2 x = 75

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 2 x = 75 by 2:

(2 x)/2 = 75/2

Hint: | Any nonzero number divided by itself is one.

2/2 = 1:

Answer: x = 75/2 = 37.5

Point B has coordinates (1,2). The x-coordinate of point A is negative 8. The distance between point A and point B is 15 uni

olchik [2.2K]

Answer:

The point A will be (-8,14) or (-8,-10).

Step-by-step explanation:

Point B has coordinates (1,2) and the x-coordinate of point A is - 8.

Let us assume that the coordinates of point A are (-8,k).

Now, given that the point A is 15 units apart from point B.

Therefore, from the distance formula, we can write that

$\sqrt{(1 - ( -8))^{2} + (2 - k)^{2}} = 15$

Now,squaring both sides, we get

$(1 - ( -8))^{2} + (2 - k)^{2} = 225$

⇒ $(2 - k)^{2} = 225 - 9^{2} = 144$

⇒ 2 - k = ± 12

⇒ k = 14 or -10.

Therefore, the point A will be (-8,14) or (-8,-10). (Answer)

We know that the distance between two points on the coordinate plane ( $x_{1}, y_{1}$ ) and ( $x_{2}, y_{2}$ ) is given by

$\sqrt{(x_{1} - x_{2})^{2} + (y_{1} - y_{2})^{2}}$ .

What is 32/36 in simplest form?

Sav [38]

Answer:

8/9

Step-by-step explanation:

To get a fraction into the simplest form you need to find a common multiple that could divide into both the numerator and the denominator. Then it will decrease.

32 / 4 = 8

36 / 4 = 9

I hope this helps :D
