Answer: The exponent of x = -45
The exponent of y = -42
Step-by-step explanation:
Since, the exponent of a variable is the power of the variable.
Given expression is,





Since the power of x = -45
⇒ The exponent of x = -45
Similarly, the exponent of y = -42.
Set it up as a ratio:
16 ounces feeds 80, 12 ounces feeds X
16 / 80 = 12 / X
Cross multiply:
16X = 80*12
16X = 960
Divide both sides by 16:
X = 960 / 16
X = 60
12 ounce feeder will feed 60 hummingbirds.
