Part A:
-np - 70 < 40
+70
-np < 110
-n < 110/p
Part B
4w-7k=28
-7k=28-4w
7k=4w-28
k=4/7w-4
1) 2 * (10 * 7 + 7 * 1,25 + 10 * 1,25) = 2 * (70 + 8,75 + 12,5) = 2 * 91,25 = 182,5 square inches - a surface area
2) 182,5 * 0,012 = <span>$</span>2,19 - answer.
Answer:
15 pages
Step-by-step explanation:
45/15=3
3x5=15
F(x) = 5x
for f(7) you replace x with 7 so it will be : f(7) = 5(7) = 35
Could you post a picture with the graphs in it? Kinda hard to answer your question without the answer choices :)
