Answer:
Let's say that the whole book have 5a pages.
First day: a + 12
Second day: (4a)1/4+15= a + 15
Third day: (1/3)[ 4a - (a+15)] +18= a + 13
Forth day: 70
So we get this:
(a + 12) + (a + 15) + (a + 13) + 70 = 5a
a + 12 + a + 15 + a + 13 + 70 = 5a
3a + 110 = 5a
3a - 5a = -110
-2a = -110
a = 55
5a = 5(55) = 275
So the total pages are in the book is:
275 pages
Answer:
30 days
Step-by-step explanation:
3/10 is completed in 9 days, so 6/10 in 18 days and 9/10 in 27 days.
If it only takes 9 days for 3/10, then 9 divided by 3 = 3. The final 1/10 is completed in 3 days. This all equals 30 days.
I could be wrong, but that's what I think.

Explanation:
Domain is the x-values. Since the graph goes forever horizontally, any x-value is on the graph.
Range is the same but with y-values. If the graph went on further than what the picture shows, then it also would show that every y value is on the graph
hope this helps
Answer:
b = 73°
Step-by-step explanation:
Since SR and ST are congruent then the triangle is isosceles.
Thus the base angles R and T are congruent, so
b = 73°
