Answer:
n - (-6) < 9
n < 3
Step-by-step explanation:
When setting up an inequality, using the key words from the problem will help. The word 'difference' would indicate subtraction and 'less than' would be the '<' inequality sign. Since the expression is 'the difference of a number and -6', we write:
n - (-6) < 9
Whenever we subtract a negative number, we change both signs to positive:
n + 6 < 9
Using inverse operations to solve: n + 6 - 6 < 9 - 6
n < 3
There would be 6 shapes, and it would depend on what those shapes are since you wouldn't know the measurements.
80 degrees since the corrisponding angle, A, is also 80 degrees
1 centimeter is equivalent to 10 millimeters. So 15x10=150 millimeters.
Hope this helped! :D
