Answer:
3C + 5 T = 550
C+T= 122
PUT IN 1 T= 122-C
3C + 5 (122-C)=550
3C -5C + 610=550
-2C= 550 - 610= -30
C= 15
T= 122-15 = 107
Step-by-step explanation:
Answer: 50
Let x be the number of cars and y be the number of trucks .
By considering the given information, we get
Multiply (1) by 3 , we get
Eliminate equation (3) from (2), we get
Put y= 72 in equation (1), we get
Hence, the number of cars did the club = 50
975 feet
1 inch = 150 feet
6.5 inches = 10 x 6.5 = 975 feet
Hope this helps!
