Answer:

Step-by-step explanation:

Jacks age: x-14

Jack's brothers age: x

In 6 years time:

Jack's age: x-8

Jack's brother's age: x + 6

Given that:

x+6 = 2(x-8)

Simplify:

x+6 = 2x-16

x+22 = 2x

2x = x+22

x = 22

we mentioned earlier that Jack's brother's age was x. but Jack's age was x-14.

So, Jack's age: 22-14 = 8

Hope this helps.

Good Luck

(Simplify your answer. Type an exact answer in terms of pi.)

likoan [24]

So the formula for the volume of a sphere is 4/3 * (π * r³)

V = 4/3 * (π * 6³)

V = 4/3 * (π * 216)

V = 4/3 * 678.24

V = 904.78

I hope this helps! If it does, please rate as Brainliest :D

A 14 foot ladder is placed against a wall. It is placed 5 feet from the base of the wall.

Vladimir [108]

Answer:

c = 18.47

Step-by-step explanation:

This would create a triangle in which the length of the wall would be the missing side. We can use the Pythagorean Theorem to find this:

1. $a^{2}$ + $b^{2}$ = $c^{2}$

2. $5^{2}$ + $14^{2}$ = $c^{2}$

3. 25 + 196 = $c^{2}$

4. 221 = $c^{2}$

5. $\sqrt{221}$ = c

6. 18.47 = c
