Answer: b = 1850 - 120w
Step-by-step explanation:
Let w represent the number of weeks for which the books are purchased.
They are being purchased at a steady rate of 120 books per week. This means that the number of books purchased after w weeks would be 120w.
The total number of algebra textbooks that she had initially is 1850
If b represents the number of books left after w-weeks of sales, then the linear function that models the number of books left after w weeks would be
b = 1850 - 120w
Answer:
(E) 1
Step-by-step explanation:
2r+ (2r+3 ) < 11
Combine like terms
4r+3 < 11
Subtract 3 from each side
4r +3-3 < 11-3
4r < 8
Divide each side by 4
4r/4 < 8/4
r <2
The only possible choice is 1
Answer:

Step-by-step explanation:



∠m=
(∠A+∠B)= 180-(70+40)
∠m= 70⇒ AB= AM⇒AB=18

Answer:
see explanation
Step-by-step explanation:
These are the terms of a geometric sequence with n th term formula
= a 
where a is the first term and r the common ratio
r =
=
= - 
the first term a = 64, hence
= 64
