Answer:
22 Pages
Step-by-step explanation:
Divide pages by hours to get pages per hour. 49.5/2.25 = 22 pages/hour.
She will read 22 pages in 1 hour
If you divide 2.25 by 0.25 you get 9, then divide 49.5 by 9 to get 5.5
Multiply 5.5 by four [because 2.25÷9=0.25 and 0.25 times four is 1 (1 hour)] to get 22 pages per hour if she continues at the same pace.
(4.25, - 1.75)
Under a reflection in the y- axis
a point (x, y ) → (- x, y ), thus
(- 4.25, - 1.75 ) → (4.25, - 1.75 ) ← original point
12:8
So 12 boys
8 girls
