Question

Part A: A number is increased by 54. The sum is then divided by 9. The result is 21. Write an equation to represent the description above. Use n for the number. Equation: _____________________________ Part B: Find the value of n. Show your work. n = __________________________________ Part C: Choose two numbers and use them to do the following: Write an equation that shows your first number added to n equal to your second number. Solve your equation for n. Equation: _____________________________ Solution: ______________

Answer 1

Answer:

a) equation= (n+54)/9= 21

b) n+54/9= 21

n+54= 21*9

n= 189-54

n= 135

c) two numbers chosen= 9, 16

{by using the equation to derive 16)

n+54/9= 21

9+135/9= 16

144/9= 16

16=16
