Answer:
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
Answer:
slope: 3/5

Step-by-step explanation:
42/2=21 or one triangles.
Using the <u>Pythagorean Theorem A^2+B^2=C^2</u>
<u>441+?=625</u>
or about 13.6
Answer:
3..?
Step-by-step explanation:
Answer:
Step-by-step explanation: The area of the bedroom is
A=7yd^2
The total cost is the sum of the price rates times this area.
C=A•($21+$5)/yd^2
where C is total cost.
C=7yd^2•($21+$5)/yd^2
C=$182
