Distribute (2m-5m)(-5)
Reika [66]

First Method (Distributive Property)

(2m - 5m) (-5)

Rearrange the equation to make it easier.

(-5) (2m - 5m)

In distributive property, it's all about multiplying. The -5 goes to the 2m and the 5m. Like this: (-5 • 2m) - (-5 • 5m).

-10m + 25m

15m

Second Method

(2m - 5m) (-5)

Since 2m and 5m have the same variable, we can subtract them.

(-3m) (-5)

Multiply.

15m

15m is your answer. I hope this helps!

In 2007, the population of Ecuador was estimated at
swat32

Answer:

In 2012 , the population will be 15 million

Step-by-step explanation:

We start by setting up an exponential equation that defines the increase

P(t) = I(1 + r)^t

P(t) represents the present population = 15 million

I is the population in 2007 which is 13.8 million

r is 1.6% = 0.016

t is what we want to calculate

15 million = 13.8 million (1 + 0.016)^t

15/13.8 = (1.016)^t

1.09 = (1.016)^t

ln 1.09 = t ln 1.016

t = ln 1.09/ln 1.016

t = 5.429 which is approximately 5

So in 2007 + 5 = 2012, the population will be 15 million

This is equivalent to:

(2.2533/2.59)(10^8/10^4)

(0.87)(10^4) which is:

0.87X10^4  which is equal to:  

0.87X10000 which is equal to:

8.7X1000  and since 1000=10^3 we can say:

8.7X10^3
