12 - x = 5

Subtract 12 from both sides

12 - 12 - x = 5 - 12

- x = - 7

Divide both sides by -1

-x/-1 = -12/-1

x = 7

For 12-x = 5 to be true

simplly take x on the right side of the equation and put five in the place of x.

12 - x = 5

12 - 5 = x

now 12 - 5 = 7

therefore the value of x = 7.

Suppose a population of deer in the state is 10, 289 and is growing 1% each year. Predict the population after 5 years
eimsori [14]

Answer: the population after 5 years is 10814

Step-by-step explanation:

The population growth of the deer is exponential. We would apply the formula for determining exponential growth which is expressed as

A = P(1 + r)^t

Where

A represents the population after t years.

n represents the period of growth

t represents the number of years.

P represents the initial population.

r represents rate of growth.

From the information given,

P = 10289

r = 1% = 1/100 = 0.01,

t = 5 years

Therefore,

A = 10289(1 + 0.01)^5

A = 10289(1.01)^5

A = 10814

I need help, I don’t need an explanation, just the answer
meriva

Answer:

x = 48 \:  \:  \:  \:  \:  \: y = 16

Step-by-step explanation:

y =  - x + 4y

y + x = 4y

y + x - 4y = 0

- 3y + x = 0

- x + 4y = 16

- 3y + x = 0

- 3y =  - x

y =  -  \frac{1}{3} ( - 1)x

y =  \frac{1}{3} x

4 \times ( \frac{1}{3} )x - x = 16

\frac{1}{3}x = 16

x = 48

y =  \frac{1}{3}  \times 48

y = 16

Hope this is correct and helpful

If the revenue for the week is $2000 and the labor cost consists of two workers earning eight dollars per hour who work 40 hours
arsen [322]
To find the cost of labor for one worker, you multiply the wage by the number of hours worked. 

40 * 8 = 320

Because there are two workers, now you double it. 

320 * 2 = 640

To find the percentage of the revenue that this is, you do the labor cost divided by the revenue. 

640 / 2000 = 0.32

Move the decimal two places to the right to get the percentage. 

0.32 = 32%

The labor cost is 32% of the revenue.
