Is the equation true, false, or open?
9p + 8 = 10p + 7
A.True; the expressions are the same for all values of the variables. B.False; the expressions are never the same.
C. Open; there is a variable.
9p + 8 = 10p + 7
1 = p
p has a single value
Both sides are the same if p = 1. 17=17
p is a variable, but only has value 1 if equation is satisfied.
Wheres the answers???....!!!!!!
To determine if the equation is true, false, or open, we need to solve it for the variable. Let's solve for "p":
9p + 8 = 10p + 7
First, we can simplify the equation by subtracting 9p from both sides:
8 = p + 7
Next, subtract 7 from both sides to isolate the variable:
1 = p
Therefore, we have found the value of "p" to be 1.
Since we were able to find a specific value for "p" that makes the equation true (in this case, p = 1), the equation is true.
Therefore, the correct answer is A. True; the expressions are the same for all values of the variables.
