(10,1250),(20,1400)
slope = (1400 - 1250) / (20 - 10) = 150/10 = 15
so every hr of training raises the salary by $ 15
Answer:
Felipe = 23 messages
Keisha = 31 messages
Manuel = 46 messages
Step-by-step explanation:
Keisha = K
Felipe = F
Manuel = M
=> There are a total of 100 messages.
=> K sent 8 +F => K = 8 + F
=> M sent 2 * F => M = 2F
=> F = F
=> 8 + F + 2F + F = 100
=> 8 + 4F = 100
=> 8 - 8 +4F = 100 -8
=> 4F = 92
=> 4F/4 = 92/4
=> F = 23
So, Felipe = 23 messages.
Keisha = 8 + F = 8 + 23 = 31 messages.
Manuel = 2F = 2* 23 = 46 messages.
46 + 31 + 23 = 77 + 23 = 100 messages.
So, the answer is correct.
Answer:
71.6
Step-by-step explanation:
c= 2(pi)r
c= 2(3.14)(11.4)
c=71.592
c= 71.6
2 Answers:
Choice B and Choice C
====================================================
Reasoning:
c = cost of one crate (some unknown amount in dollars)
c+20 = cost of a crate and a leash
5(c+20) = cost of five sets of items mentioned
5(c+20) = 475 is one equation we can form
5c+100 = 475 is another equation we can form
I used the distributive rule to go from 5(c+20) to 5c+100.
The 100 indicates that the five leashes combine to $100, since 5*20 = 100.
The 5c represents the cost of all five crates combined.
So 5c+100 is another way to express the total cost of all five crates and all five leashes.
---------------
Side note: Solving either equation leads to c = 75, meaning that each crate costs $75.
