Now the same in math:

Divide both sides by .5
n= £ 35
The answer is D because when you put the missing value which is x you replace it to 10 and then you solve it I hope this helps
You convert 432 sq inches into inches so 20.7846. Then you times that by 6. The answer is 124.7076 and if rounded 124.7
It's kind of like division and mutliplycation I guess
The rule is that: You are adding 5 each time
5(100) + 4 = 504
Your answer should be 504
hope this helps
