Solve for x <br> 5(x-10)=30-15x

timofeeve [1]

Answer:

solution :

x = 4

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

5*(x-10)-(30-15*x)=0

Step by step solution :

Step 1 :

Equation at the end of step 1 :

5 • (x - 10) - (30 - 15x) = 0

Step 2 :

Step 3 :

Pulling out like terms :

3.1 Pull out like factors :

20x - 80 = 20 • (x - 4)

Equation at the end of step 3 :

20 • (x - 4) = 0

Step 4 :

Equations which are never true :

4.1 Solve : 20 = 0

A type of bacteria has a very high exponential growth rate of 80% every hour. If there are 10 bacteria, determine how many will

Lana71 [14]

<h3>There are 189 bacteria in 5 hours</h3><h3>There are 13382588 bacteria in 1 day</h3><h3>There are $10(1.8)^{168}$ bacteria in 1 week</h3>

<em><u>Solution:</u></em>

Given that,

A type of bacteria has a very high exponential growth rate of 80% every hour

There are 10 bacteria

<em><u>The increasing function is given as:</u></em>

$y = a(1+r)^t$

Where,

y is future value

a is initial value

r is growth rate

t is time period

From given,

a = 10

$r = 80 \5 = \frac{80}{100} = 0.8$

<em><u>Determine how many will be in 5 hours</u></em>

Substitute t = 5

$y = 10(1 + 0.8)^5\\\\y = 10(1.8)^5\\\\y = 10 \times 18.89568\\\\y \approx 188.96$

y = 189

Thus, there are 189 bacteria in 5 hours

<em><u>Determine how many will be in 1 day ?</u></em>

1 day = 24 hours

Substitute t = 24

$y = 10(1 + 0.8)^{24}\\\\y = 10(1.8)^{24}\\\\y = 10 \times 1338258.84\\\\y = 13382588.45\\\\y \approx 13382588$

Thus, there are 13382588 bacteria in 1 day

<em><u>Determine how many will be in 1 week</u></em>

1 week = 168

Substitute t = 168

$y = 10(1 + 0.8)^{168}\\\\y = 10(1.8)^{168}$

Thus there are $10(1.8)^{168}$ bacteria in 1 week

Bryson buys a bag of 64 plastic miniature dinosaurs . could he distribute them equally into six storage containers and not have

MariettaO [177]

Okay so first you would ask your self does 64 divide by 6? So take out your calculator and divided 64 by 6. Doing so you find out the answer is 10.6 (repeating)
So each storage container would get 10? No that doesn't sound right, instead you have to turn the repeating 6 into a fraction so it would be each storage container gets 10 2/3 of a dinosaur.
