a.) Solve a - 9 = 20
b.) Solve b - 9 > 20
c) How is solving the equation in part a similar to solving the inequality in part b?
d.) How are the solutions different?
a - 9 = 20
a = 29
b - 9 > 20
b > 29
The solutions are different because A is 29. B is greater than the number 29. Whatever number B is it's greater than 29.
You're welcome, Jenny.
Ok, I under stand thnx. Ms.Sue!
but how they different tho...?
a.) To solve the equation a - 9 = 20, you want to isolate the variable a.
Start by adding 9 to both sides of the equation to cancel out the -9 on the left side:
a - 9 + 9 = 20 + 9.
Simplifying further, you get a = 29.
So, the solution to the equation a - 9 = 20 is a = 29.
b.) To solve the inequality b - 9 > 20, you also want to isolate the variable b.
Start by adding 9 to both sides of the inequality: b - 9 + 9 > 20 + 9.
Simplifying further, you get b > 29.
So, the solution to the inequality b - 9 > 20 is b > 29.
c.) Solving the equation in part a and the inequality in part b are similar in the first step, which is to add 9 to both sides. This step is performed to eliminate the -9 term on the left side and move the constant term to the other side of the equation or inequality.
d.) The solutions to the equation in part a and the inequality in part b are different.
In part a, the solution is a single value, a = 29, which means that the variable a equals 29.
In part b, the solution is an inequality, b > 29, which means that the variable b can take any value greater than 29. The solution represents a range of possible values for b.
