Step-by-step explanation:
1. Think about what numbers multiply to -20: -10 and 2, 10 and -2, -20 and 1, 20 and -1, 4 and -5, -4 and 5

Answer:
64 single-shot espressos
Step-by-step explanation:
Let's say that the cafe sold x single-shot espressos. The total number of espressos sold was 80, and 80% of that total 80 were single-shot. So, we have the equation:
x = 80% * 80
Remember that % just means "out of 100". So, 80% = 80/100:
x = (80/100) * 80 = 6400/100 = 64 single-shot espressos
Hope this helps!
That "equation" has an infinite number of "solutions", because
no matter what 'r' is, it's always a true statement.
The statement is equivalent to saying "I am I." or "You are you."
The equation is y = 1/2 x + 13, where x is the number of days, and y is the length of the barrier
