Answer:
.
Step-by-step explanation:
We are told that a man drove x miles per hour for 3 hours, so he traveled 3x miles in three hours.
We are also told that he drove (2x-60) miles per hour for the next 4.75 hours. So The distance traveled by in next 4.75 hours will be:
To find the total distance traveled by man we will add distances traveled by him in first 3 hours and next 4.75 hours.
Upon combining like terms we will get,
Therefore, the total distance traveled in terms of x will be .

Answer:
1. x= 122(answer on pdf=n)
2. x=38(answer on pdf=s)
7. x=26(answer on pdf=l)
8. x=14(answer on pdf=p)
13. x=22(answer on pdf=b)
14. x=12(answer on pdf=k)
Step-by-step explanation:
Supplementary angle for number 1 so 58+x=180
180-58=x=122
Number 2 is a complimentary angle so 52+x=90
90-52=x=38
Number 7 is a complimentary angle so 64+x=90
90-64=x=26
Number 8 it states that the angles are equal so 4x=56
56/4=x=14
Number 13 is a supplementary angle so (6x-2)+50=180
(180-50+2)/6=x=22
132/6=x=22
Number 14 is complimentary so 8x-6=90
96/8=x=12
