Answer: B
Step-by-step explanation:
By the Exterior Angle Theorem, we know that the exterior angle is equal to the sum of the two opposite interior angles.
(2x+8)+(3x+5)=123 [combine like terms]
5x+13=123 [subtract both sides by 13]
5x=110 [divide both sides by 5]
x=22
Now, we know that the answer is B.
The answer for this qeustion is C.
Since 25% is 1/4 of 100% then you do 4 times 15 and that equals 60.
In the word replacement, there are 11 letters.
4 of them are vowels : e, a, e, e
7 of them are not vowels : r, p, l, c, m, n, t
The probability of getting a vowel the first try is 4/11.
The probability of getting something that is not a vowel is 7/10. The denominator is one less because the vowel card is not replaced, meaning there is one less card to choose from.
Multiply.
4/11*7/10
=28/110
=14/55
The probability is 14/55.
Hope this helps!
