What is this problem

sergeinik [125]

Answer:

$m=A-\frac{2n}{Z}$

Step-by-step explanation:

Multiply by 2:

2n = Z(A - m)

Divide by Z:

$\frac{2n}{Z} =A-m$

Subtract A:

$-m=\frac{2n}{Z}-A$

Multiply by -1:

$m=A-\frac{2n}{Z}$

How does 3x = 4(x-2.25) = 9. Wherethe hell is everyone getting a 9?!?! At a bargain store, Tanya bought three items that each co

andrew11 [14]

Answer:

Step-by-step explanation:

Here is how to get 9:

3x = 4(x - 2.25)

Solve 4(x - 2.25)

3x = 4x - 9

Move the variable to the left side and change it's sign

3x - 4x = -9

Combine like terms

-x = -9

change the signs

x = 9

There ya go! I hope this isn't too confusing!

A pilot knows she descended 1,000 feet and traveled a diagonal distance of 18,000 feet.

Arada [10]

The horizontal distance covered by pilot is 17,972.2 feet.

Step-by-step explanation:

Given,

Distance covered descending = 1000 feet

Diagonal distance = 18,000 feet

The horizontal distance will form a right triangle, therefore, we can find the horizontal distance by using pythagoras theorem.

Here,

a = 1000

b = horizontal distance

c = 18000

$a^2+b^2=c^2\\(1000)^2+b^2=(18000)^2\\1000000+b^2=324000000\\b^2 = 324000000-1000000\\b^2=323000000$

Taking square root on both sides

$\sqrt{b^2}=\sqrt{323000000}\\b=17972.2$

The horizontal distance covered by pilot is 17,972.2 feet.
