Vsevolod [243]4 years ago

Answer:

x = 25

Step-by-step explanation:

In any triangle, the sum of all 3 angles is ALWAYS 180 degrees. So we can make this into an equation.

4x + 2x+ 10 + x - 5 = 180

Now we combine the like terms.

7x + 5 = 180

Subtract 5 from both sides.

7x = 175

Now divide by 7 on both sides.

x = 25

densk [106]
There will be 17 quarters in the bag (12 which are state and 5 which are regular). The probability of the state quarters picked on the first try would be 12/17 while the probability of the second will be 5/17. If Rees put the state quarter back in the jar, then probability that the second quarter will be a regular quarter will remain 5/17.

How many four element subsets of \{1, 2, 3, 4, 5, 6, 7\}{1,2,3,4,5,6,7} have 11 as an element but do not have 77 as an element
levacccp [35]

If we fix 1 to be an element of a subset of size 4, then we can choose from 5 other elements (2, 3, 4, 5, and 6) to fill the other 3 spots in the subset. So there are

\dbinom53 = \dfrac{5!}{3!(5-3)!} = \boxed{10}

such subsets.
