Hi!

4x+4=2x+10

Move all the numbers to the right and all the variables to the left, using the opposite operation:

4x-2x=10-4

2x=6

Divide both sides by 2:

x=3 (Answer)

Hope it helps!

Enjoy your day!

I literally have no clue how to do this.
timurjin [86]

Answer:

Step-by-step explanation:

Sine is opposite divided by the hypotenuse.

sin(30) = 9/y

1/2 = 9/y

y = 18

Cosine is adjacent divided by the hypotenuse

cos(30) = x/18

\frac{\sqrt{3} }{2}=x/18\\x=9\sqrt{3}=15.6

8. Solve.
trapecia [35]

Answer:

48 assistants

Step-by-step explanation:

If 1 executive has an average of 1.5 assistants, let x represent the number of assistants that are employed if there are 32 executives in the office.

Thus:

1.5 assistants to 1 executive = x assistants to 32 executives

1.5 : 1 = x : 32

\frac{1.5}{1} = \frac{x}{32}

Cross multiply

1.5*32 = x*1

48 = x

Therefore, 48 assistants were employed in the office.

An article describes a study in which a new type of ointment was applied to forearms of volunteers to study the rates of absorpt
irinina [24]

Answer:

There were 28 different choices for the six locations to apply the new ointment

Step-by-step explanation:

The order in which the location are chosen is not important, which means that we use the combinations formula to solve this question.

Combinations formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

Two events, A and B are independent, if:

P(A \cap B) = P(A)P(B)

How many different choices were there for the six locations to apply the new ointment?

Six locations from a set of 8. So

C_{8,6} = \frac{8!}{6!2!} = 28

There were 28 different choices for the six locations to apply the new ointment
