Answer: The answer is 14
Step-by-step explanation: So, for every 5 books she gets, she gets two free. Here is a chart
5 books bought=2 free books
10 books bough=4 free books
15 books bought=6 free books
20 books bought=8 free books
25 books bought=10 free books
30 books bought=12 free books
35 books bought=14 free books
Every five books bought equals two free books, so if she buys 35 she would get 14, so 49 books in all. hope this helps :)
Answer:
x = 8
Step-by-step explanation:
Complimentary angles are angles that add up to 90 degrees. If ABC and DBC are complimentary, then when added together, it equals 90 degrees.
ABC + DBC = 90
6x+13+4x−3 = 90
10x+10 = 90
10x = 80
x = 8
Answer:
the answer is option A population standard deviation
Domain are those values of x for which function is defined. f(x) is not defined at x = 3. Therefore Domain is
x∈ (⁻∞, +∞) - {3}
Let x = liters 20% solution to be added
then
.12(12) + .20x = .14(12+x)
.12(12) + .20x = .14(12+x)
1.44 + .20x = 1.68 + .14x
.20x = .24 + .14x
.06x = .24
x = 4 liters
Hope this helped!!
