Answer:
The length of JM is 40
Step-by-step explanation:
Since 7x+5 and 8x are both equal, we can make this equation:
7x+5=8x
-7x -7x
x=5
7(5)=35
35+5=40
Answer: 9600cm
Step-by-step explanation: 120
*80
9600
The answer is 16.3 since
-4.7 is below zero, to get it to zero you would have to add the 4.7 back on. and 11.6+4.7 is equal to 16.3
Well, since you have two variables in one equation, you would have to have at least one other equation to solve this problem. Their isn't enough information to solve this alone, sorry :/
