Club A:   25+30x   where x is the number of lesson

Club B   55 + 20x where x is the number of lesson

when is the cost equal

25+ 30x = 55 + 20x

subtract 20 x from each side

25+ 30x -20x = 55 - 20x

25+ 10x = 55

subtract 25 from each side

25-25+ 10x = 55 - 25

10 x = 30

divide by 10

10x/10 = 30/10

x = 3

After 3 lessons the cost is equal

Chris has a blue coat and a
Tju [1.3M]

Answer: P = 0.125 = 1/8

Step-by-step explanation:

We know that he has a blue coat and a black coat.

If he dresses at random, then the probability of getting the blue coat is equal to the quotient between the number of blue coats (1) and the total number of coats (2).

Then the probability is:

p = 1/2

We also know that he has blue pants and brown pants, the probability of getting at random the blue pants is calculated in the same way than above, then:

q = 1/2

And for the shirt he has a blue shirt and a red one, the probability of randomly selecting the blue one is calculated in the same way than above, then:

k = 1/2

Now, the joint probability (he selects all blue clothes) is equal to the product of the individual probabilities:

P = p*q*k = (1/2)*(1/2)*(1/2) = 1/8 = 0.125

You just reflected on working with right triangles and trigonometric concepts. How important were concepts that you learned prev
harina [27]

Idk if ya still need it or if this will help but this is what i put for mine

 Concepts that I had previously  learned about are quite important because math goes hand and hand. if you try to skip something and go ahead you'll most likely get confused because there could of been something highly important to that would help you understand whats ahead. in the previous unit it tells you about triangles and their description like a right triangle-90 degree angle and where legs and hypotenuse is located, this unit has had a ton about right triangles.

Write −12.405 as a mixed number in simplest form
serious [3.7K]

Answer:

-12\frac{81}{200}

Step-by-step explanation:

In the decimal of −12,405, leave the −12 and divide 405 by 1000 for now:

\frac{81}{200} = \frac{405}{1000}

Greatest Common Divisor [GCD]: 5

Finally, you attach this back to the −12, giving you -12\frac{81}{200}.

I am joyous to assist you anytime.
