Using mental math, solve the inequality 7+a>5+6 . In the solution set, the variable a must be greater than what number?(1 point)
To solve the inequality, we can start by simplifying both sides of the equation.
7 + a > 5 + 6
Adding 7 to both sides:
7 + a + 7 > 5 + 6 + 7
Simplifying:
a > 18
Therefore, the variable a must be greater than 18.
that is worng
I apologize for the incorrect response. Let's solve the inequality again:
7 + a > 5 + 6
Simplifying both sides:
7 + a > 11
Next, subtract 7 from both sides:
a > 11 - 7
Which simplifies to:
a > 4
Therefore, the variable a must be greater than 4.
