To find the average you would add the three numbers together 169.74+235.95+219.21
to get a total of $624.90 divide that number by 3 to get the average which is $208.30 as the average sale per day
Answer:
no
Step-by-step explanation:
5+3x is equal to 8x.
if there is no number in front of a variable, it is understood to be a one. so 1-x would basically be 1-1. this cancels out the x, making it impossible for the equivalent equation to be 8 - 8x
The answer is George washington.

Let's apply trivial identities here. We know that cos(-π / 4) = √2 / 2, sin(-π / 4) = - √2 / 2, cos(-π / 2) = 0, sin(-π / 2) = - 1. Let's substitute those values,

As you can see your solution is the last option.
Answer:
2:1
2=5780
1=2890
Step-by-step explanation:
2/2+1=2/3×86,70=5780
1/2+1=1/3×8670=2890
