Step-by-step explanation:
Imagine placing 10 apples in a row.
We have an extra 2 baricades that we can place between any 2 apples, so that a total of 3 groups will be formed.
This is the same as choosing 2 of the 12 items to be barricades.
Hence the answer is 12C2 = 66.
Answer:
X = 56
Step-by-step explanation:
Subtracting 169 degrees from a straight line (180 degrees) gives you 11 degrees. with this information you can add 11 and 114 to get 124. Then you can subtract that amount from 180 (the measure of any triangle) and get your answer which is 56. I hope this helped!
Answer: the number = 6
Step-by-step explanation:
<u>Let x be the number.</u>
<u>Set equation according to the information given</u>
2 + 8x = 2 × 25
<u>Simplify by multiplication</u>
2 + 8x = 50
<u>Subtract 2 on both sides</u>
2 + 8x - 2 = 50 - 2
8x = 48
<u>Divide 8 on both sides</u>
8x / 8 = 48 / 8

Hope this helps!! :)
