Explanation

Given the points (x + 5, 8) and (9, y - 6) are equal, we can set up the equations:

x + 5 = 9 ... (1)

8 = y - 6 ... (2)

Solving (1):

x = 9 - 5

x = 4

Solving (2):

y = 8 + 6

y = 14

The values of x and y are x = 4 and y = 14.

Explanation

Given:

(x, 6) = (2, y - 6)

Equating the corresponding components:

x = 2

6 = y - 6

Solving for y:

y = 6 + 6

y = 12

Now, finding x + y:

x + y = 2 + 12

= 14

Explanation

"Disclear" is not a correct English word — the proper word is "unclear."

The sentence should be: "I'm unclear about what you want me to do."

Explanation

Given:

10 pipes fill the tank in 1 hour 40 minutes = 100 minutes

Let's find the rate of 1 pipe:

Rate of 10 pipes = 1 tank / 100 minutes

Rate of 1 pipe = 1 tank / (10 × 100) minutes

= 1 tank / 1000 minutes

Rate of 8 pipes = 8 tanks / 1000 minutes

= 1 tank / (1000 / 8) minutes

= 1 tank / 125 minutes

Explanation

Let's use the Pythagorean theorem:

Height of pole (perpendicular) = 12m

Length of string (hypotenuse) = 20m

Distance between foot of pole and end point of string (base) = √(hypotenuse² - perpendicular²)

= √(20² - 12²)

= √(400 - 144)

= √256

= 16m
