Lara can read 10 chapters in 4 hours.
At this rate, she can read half that many chapters in half the time.
So she reads 5 chapters in 2 hours.
So Lara reads 10 chapters in 4 hours,
+ 10 chapters in 4 more hours,
+ 5 chapters in 2 more hours.
That's 25 chapters in total, and 10 hours in total, ya? :)

Answer:
48,58
Step-by-step explanation:
Let The speed of the west bound train be x
Let the east bound train be x+10
The speeds can be calculated as follows
2(2x+10)= 232
4x + 40= 232
4x= 232-40
4x= 192
x= 192/4
= 48
Hence the speedof the west bound train is 48
The speed of the east bound train is 48+10
= 58
Answer:
identical in form or shape
Step-by-step explanation:
two triangles could be congruent as they both have 3 sides.
Simplify 6 – 4x – 2 + x
Combine like terms:
6 - 2 = 4
-4x + x = -3x
-3x + 4, or (A) is your answer
----------------------------------------------------------------------------------------------------------------
Simplify 5 – 2x – 3 + x
Combine like terms:
5 - 3 = 2
-2x + x = -x
-x + 2, or (B) is your answer
----------------------------------------------------------------------------------------------------------------
hope this helps
