i don't know hot to explain it, but technically i multiplied 1.8 time 60 (because there is 60 minutes in an hour, which will equal 108. now i multiplied 108 times 24 to see how many pages he can read in a day and it gave me 2592 and he only has to read 300 pages. So technically he can read 8 or more books of 300 pages in a day.

Please Help!! This is Geometry.​

If M is the midpoint of PQ, then PM and MQ are equal.

As PM and MQ are given , equal them to each other to solve for x.

7x+8=5x+20

Subtract 5x on both sides to get 2x+8=20

Subtract 8 on both sides to get 2x=12

divide by 2 on both sides to get x=6

Use the value of x=6 and plug it into the equations for PM and MQ to find their value.

PM=7x+8

=7(6) 8 =42 + 8 = 50

(you can already tell MQ is also 50 as PM and MQ are equal, but we still solve for MQ just for the fun of it)

MQ=5x + 20

=5(6) +20=30+20=50

PM=50

MQ=50

PQ= PM + MQ= 50 + 50 = 100

Have a great night.
