Answer:
<B =121
Step-by-step explanation:
If the angles form a linear pair, they add to 180
6x-19 + 11x-22 = 180
Combine like terms
17x -41 = 180
Add 41 to each side
17x-41+41 = 180+41
17x = 221
Divide by 17
17x/17 =221/17
x =13
<b = 11x-22 = 11*13 -22 = 143-22 =121
Answer:
Step-by-step explanation:
f(1)=45*4/5
=9*4
=36
Let’s pick a paperback and a hardback
There are 4 x 6 possible choices
Now pick any three of the remaining 8 books
8C3 = 56
This means there are 4 x 6 x 56 = 1344 selections of 5 books that will contain at least one paperback and one hardback
8C3 means picking 3 from 8 without worrying about order
8C3 = 8 x 7 x 6 / (3 x 2 x 1) = 56
The answer is C Becase all rationals are positive so to get the answer make them negative so c is the answer
5 quarters and 8 dimes would be the correct answer because
10x8=80
25x5=125
125+80=205
