Identify the coefficient(s) in the following expression: 10x + 5y – 8y
2 answers:
A coefficient is the quantity before a variable that multiplies the variable. For example, for 
, 11 is the coefficient. For 
, 1 is the coefficient.
Here, there's a 10 in front of the x-term, a 5 in front of the first y-term, and a –8 in front of the second y-term. These are your coefficients, but your teacher may want you to simplify first.
. If this is the case, then the coefficients are 10 and –3.

Answer:
793.25 mi/hr
Step-by-step explanation:
Given that:
The radius of the earth is = 3030 miles
The angular velocity =
If a jet flies due west with the same angular velocity relative to the ground at the equinox;
We are to determine the How fast in miles per hour would the jet have to travel west at the 40th parallel for this to happen.
NOW;
Distance s is expressed by the relation
s = rθ
s = 793.25
The speed which depicts how fast in miles per hour the jet would have traveled is :
v = 793.25 mi/hr
Hence, the jet would have traveled 793.25 mi/hr due west at the 40th parallel for this to happen.
