30 points and \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:

Part A) The equation that represent the situation is

Part B) The value of n is

Part C) The equation is and the solution is

Step-by-step explanation:

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

Let

n-----> the number

we know that

The linear equation that represent this situation is equal to

Part B) Find the value of n

we have

solve for n

Multiply by 9 both sides

Subtract 54 both sides

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

I choose 35 and 60

Solve for n

Subtract 35 both sides

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

step-by-step explanation:

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen
