200 divided by 5 equals 40.
So therefore, 40 times 5 equals 200.
Part a), solve this system of equations:
x + y = 5
x - y = 2.25
2x = 7.25
x = 3.625
y = 1.375
part b), solve this system of equations:
x + y = 5
x = 3y
y = 1.25
x = 3.75
The first thing we must do for this case is to see how many representatives from each country attended.
We have then:
Argentines = (1/6) * (120) = 20
Chileans = (1/5) * (120) = 24
Bolivians = (1/4) * (120) = 30
Venezuelans = (1/4) * (120) = 30
Adding we have:
20 + 24 + 30 + 30 = 104
Therefore the number of Americans is:
120-104 = 16
Answer:
16 Americans attended the wind energy conference
Answer:
The shortcuts is
Divide number of units by 100
Step-by-step explanation:
From the question we are told that
insulin u-100 is 
From the data given above we see that
100 units of insulin u-100 is contained in 1 mL
So 1 unit of u-100 is contained in x mL
=> 
This means that a unit of insulin u-100 occupies 
So we can represent a single unit of insulin u-100 as 
Now if 1 unit of insulin u-100 is represented as 
Then y unites of insulin u-100 is represented as z
So

From the above calculation we can see that the shortcuts to convert u-100 insulin given in units, to mL is to divide number of units by 100
20% off $250, 250 x 0.2= 50
The suit is $50 off, so $250-$50= $200
