15 over 76,894 and x over 100. You cross multiply15 with 100 which gives you 1500 and divide by the number you have left, 76,894. You get 0.0195073738. Make sure you round!

Answer:

The last year population was 66864.

Step-by-step explanation:

It is given that the population of a town grew 15% up to 76,894.

Let the last year population be x.

The population increased by 15% up to 76894.

x+\frac{15}{100}x=76894

\frac{100x+15x}{100}=76894

\frac{115x}{100}=76894

115x=7689400

x=66864.3478

x\approx 66864

Therefore, the last year population was 66864.

Transform the equation to isolate x: ax = bx + 1. How is
shepuryov [24]

Answer:

x=\frac{1}{a-b}

The value of x is inversely proportional to the difference of <em>a</em> and <em>b</em>.

Step-by-step explanation:

The given expression is ax-bx+1

We factor the left hand side to get:

(a-b)x=1

We divide both sides by: a-b

x=\frac{1}{a-b}

Observe that the difference of a and b is in the denominator.

The whole is of the form: x\propto \frac{1}{a-b}

The value of x is inversely proportional to the difference of <em>a</em> and <em>b</em>.

Associative property of (21)(7)(3x) ? <br> PLEASE HELPPPP <br> 40 PTS!!!!
sdas [7]
Ehh, now it's letting me answer.

So the associative property is basically as long as it's addition or multiplication,  you can move around the groupings and it will still be the same.

For example, you can say:(21 * 7) (3x)  instead of (21)(7)(3x)

And it would be equal to the old version.

(To answer your other question, the commutative property is you can move around all the parts of the equation as long as it's addition or multiplication.)

So basically, it would be the first one you sent me.
