Answer:
87.92 square inches
Step-by-step explanation:
Surface area for cylinder is given by 
where r is the radius and h is the height of cylinder.
Given that candle is cylindrical in shape
Thus, Surface area for candle is calculated as given below\\
Thus, total surface area for candle is 87.92 square inches.
Change them into improper fractions
and then find a common denominator, then minus, add, whatever for each one
Since both equations are equal to y you can just make them equal to each other, like this 3x + 7 = x - 9. From there isolate the varible x on one side so that the solution will be on the other side of the equation. I'll do the steps too for you.
3x + 7 = x - 9
2x + 7 = -9
2x = -16
x = -8
Hope this helps :)
Answer:
The total money in account after 8 months is $72 + $8 x
Step-by-step explanation:
Given as :
Total money available in saving account = $72
The money saves each month in account = $x
So, The money saves in account after 8 months = $x × 8 = $8 x
Let The total money in account after 8 months = $A
Or, A = money available in saving account + money saves in account after 8 months
i.e A = $72 + $8 x
So, The total money in account after 8 months = A =$72 + $8 x
Hence, The total money in account after 8 months is $72 + $8 x Answer
