Answer:
64
Step-by-step explanation:
First of all substitute the values to where ever you see their corresponding variables to make them multiply.
x = 9
y = 3
z = 2
so we get
8x as 8(9),
7z as 7(2)
2y as 2(3)
then the it's will be
8(9) - 7(2) + 2(3)
which is
72 - 14 + 6
finally we get
64
The answer to this is 30.41 due to the zero the answer cannot be moved on so it will stay the same.
The grizzly bears heart would drop 20% during hibernation
5.6x10^-3 yd/year in feet per day.
There are 3 feet in a yard
(5.6x10^-3)x3=1.68x10^-2 feet/year
Let's take there to be 365 days in the year (Fun fact: The actual duration of our year is <span>365 days 5 hours, 48 minutes 46 seconds)
