18 bikes, 9 have gears (G), 11 have suspension (S) and 5 with both,What is the probability that a bike with suspension or gears?
vichka [17]

Answer:

  • 5/9

Step-by-step explanation:

  • Total number of bikes = 18
  • Bikes with gears S = 9
  • Bikes with suspension S = 11
  • Bikes with both GS = 5

<u>From the information above we have:</u>

  • Bikes with gears only = 9 - 5 = 4
  • Bikes with suspension only = 11 - 5 = 6

<u>Sum of the above two gives us the number of bikes with suspension or gears:</u>

  • 4 + 6 = 10

<u>Probability of selected bike be G or S is:</u>

  • P(G or S) = 10/18 = 5/9

I need help with like terms
professor190 [17]
I’m guessing you mean like this.
2x+4y+5x+8y.
2x and 5x are like terms because the x’s are alike. If you add 2+5, the answer is 7. So therefore 2x+5x=7x.

4y and 8y are like terms because the y’s are alike. So the answer to 4y+8y would be 12y.

If you need extra help, give me a problem and I will help you solve it.

I need help on this, picture is attached below
Paladinen [302]
<h3>Answer:  37 degrees</h3>

=====================================

Explanation:

Refer to the diagram below. I've marked angles FBD and ECG in red. We can see that they are alternate exterior angles because they are

Outside (aka exterior) of the parallel lines

On alternating sides of the transversal cut

Because JD is parallel to EK, this means the alternate exterior angles are congruent. Therefore, angle ECG is also 37 degrees.

Ignore angle ABG and ignore line AH. In my opinion, this is filler added as a distraction.
