yes x is the same in both problems

Step-by-step explanation:

Use inverse operations and properties of equality to isolate the variable m+31=307

otez555 [7]

ANSWER

$m = 276$

EXPLANATION

The given equation is

$m + 31 = 307$

We add the additive inverse of 31 which is -31 to both sides of the equation to get,

$m + 31 + - 31= 307 + - 31$

Simplify;

$m +0= 307 - 31$

$m = 276$

A certain forest covers an area of 3900 km2 . suppose that each year this area decreases by 8% . what will the area be after 10

stiv31 [10]

A = P(1-r)^t

A = 3900(1-0.08)^10

A = 3900(0.92)^10 

A = 3900(0.434388454)

A = 1694.11

1694 square km

What is the simplified form?

yarga [219]

Answer:

$\frac{6}{5x^{10}}$

Step-by-step explanation:

Step 1: Simplify square roots

√72 = 6√2

√50 = 5√2

So, $\frac{x^86\sqrt{2} }{x^{18}5\sqrt{2} }$

Step 2: Cancel like terms

$\frac{6}{x^{10}(5)}$

Step 3: Rewrite

And we should get our answer!
