Answer:
Step-by-step explanation:
Set up a ratio in the form of pages/minute:
then fill in next to that how many pages per minute George can read:
Now we want to figure out how long (time is our unknown, so we call that x) it will take him to read 85 pages. The 85 goes in a ratio on the same line as the other number of pages:
Cross multiply to get 15x = 1020
Now divide both sides by 15 to get x = 68 minutes, which is an hour and 8 minutes.
X = 7
The angles are congruent so you’d do, 4x-5=23 and you’d get x = 7
2(v-4)-10=-2(4v-1)
2v-8-10=-8v+2
2v-18=-8v+2
10v-18=2
10v=20
v=2
