Answer:
The highest common factor of 70 and 126 is 14.
Step-by-step explanation:
Carly : y = 60x + 40
janiya : y = 50x + 80
60x + 40 = 50x + 80
60x - 50x = 80 - 40
10x = 40
x = 40/10
x = 4 <=== so at 4 weeks, they will have the same amount of money <==
The money they have is : y = 60(4) + 40.....y = $ 280 <=
so ur answer is : 4 weeks, $ 280
The answer should be B, but I might be wrong.
( 1:3 ) is equivalent to 2:9
( 20 trillion : 60 trillion ) is equivalent to 3:9
Your expression represents the total distant traveled. 25t tells you depending on how long you drove, the distance for that period. Then you also drove 45mi/h for an unknown time as well. So adding them gives you the entire distance driven.
