1155/7=165
1485/9=165
Answer:
20n
Step-by-step explanation:
One pretzel has 20 calories. Write an algebraic expression for the total number of calories in n pretzels.
1 pretzel = 20 calories
n pretzel = x
Cross Multiply
x × 1 pretzel = n pretzel × 20 calories
x = n pretzel × 20 calories/1 pretzel
x = 20 n
Therefore, an algebraic expression for the total number of calories in n pretzels = 20n
Hope this helps! I have to type more words apparently for me to send this. Ok that should work!
g(x) cannot have an inverse because it gives the same output value for two individual input values.
In this case, g(x) is 5 when x is both 3 and -1. Hence, g(x) does not have an inverse.
Let me know if you have any questions, thanks!
