Answer:
No, because 6+8=15 is not true
Answer:
Step-by-step explanation:
Let H and P represent the number of history and physics textbooks.
We are told that:
1) H + P = 236/week, and
2) H = 3P [A disgrace, but that's a different problem]
We can substitute the definition of H in the second equation into the first:
H + P = 236/week
3P + P = 236/week
4P = 236
P = 59
H = 3P, so H = 3*(59) or 177
59 Physics and 177 History books for a total of 236 books sold that week.
Answer: Choice A) It has a range of 17
Reason:
The smallest value is 8 and the largest is 14. The range is the distance between these min and max
range = max - min = 14 - 8 = 6
So the range is 6 instead of 17.
The ratio = 15/20 = 3/4
21/x = 3/4
x = 28
