The cost of fencing (C)
The cost is calculated as:

Let:

So, we have:



<em>The question cannot be solved further since the dimension of the fence is not given</em>
<em>If you know the dimension, calculate the fence perimeter and substitute the value for x</em>
First you want to change the 4% to a fraction so 4/100. Then you have to figure out if 4/100 or 1/10 is larger. 4/100 reduces to 1/25. So the 1/10 or 1 in 10 is more often then the 1/25 or 1 in 25.

Answer:
2 and 5 for sure. I think 4 is correct, but your teacher may not.
Step-by-step explanation:
The given expression reduces down to -7m - 8 = m - 4
1 cannot give -15m on the right. One seldom sees that mistake on Brainly.
3 does not do that. - 3m is not - 7m
4 has it's sides reversed. I would count it is right, others may not. I'm trying to say the left side is on the right side and the right side is on the left. That to me is OK.
5 is Ok as well the left is written as -8 - 7m which is -7m - 8. and with -4 and m
6 has been reduced on the left incorrectly. the right is it's signs backwards
2 4(?) and 5
