Asurvey of 2,000 doctors showed that an average of 3 out of 5 doctors use brand x aspirin. how many doctors use brand x aspirin? (hint: solve for x).

1200 doctors use x aspirin

Step-by-step explanation:

X is the number of doctors using x aspiring

There is necessary an equation:

If 3 of 5 doctors use aspiring, how many from 2000 use aspiring:

Equation:

3=    X  

5   2000

lets clear X

Step 1: There is not sum or rest next to X. There is a division in the X, that number has to be moved to the other side of the equal sign but multiply the numbers.

2000*(3/5)=X

Now you have the X alone.

Lets do the formula:

1200=X

Now you have the numbers of doctors that use x aspiring.

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°

it is a function because for every x value there is only one y value

for every x value there is only one y value
