Answer:
C
Step-by-step explanation:
5 1/2 pages in 12 minutes
There are 5 sets of 12 minutes in 1 hour
5 1/2 x 5 = 27 1/2
Therefore she would read 27 1/2 pages in 1 hour
Thats essentially how i did it - sorry if its not a very good explanation.

Answer:
6a-24=6a-24
Step-by-step explanation:
you distribute the 2 on the first equation (2(3a-12)) so 2 times 3a is 6a and -12 times 2 equals -24 so the simple form for the first equation is 6a-24. You do the same for the second equation 3 times 2a is 6a and 3 times -8 is -24. So the equations are the same on each side meaning they have infinite solutions on a graph.
Exercise 1:
The angle in the low left corner is supplementar with the external angle. Since the external angle is 105, the inner angle is 75.
Since in every triangle the inner angles sum to 180, we have
Exercise 2:
Again, you need to use the fact that in every triangle, the sum on the inner angles is always 180.
Exercise 3:
Since PQ and BC are parallel, triangles APQ e ABC are similar. This means that their side are in the same proportion, so
Plug the known values of AB, AP and AC and solve for AQ:
