Answer:
Lacrosse = 62 students
Swimming = 62 students
Soccer = 124 students
Football = 186 students
Step-by-step explanation:
Based on the information, we can draw some equations
<em>1.</em> Lacrosse = Swimming
<em>2.</em> Soccer = 2 * Lacrosse
<em>3.</em> Football = 3 * Swimming
<em>4.</em> Football + Soccer + Swimming + Lacrosse = 434
Lets solve for once sport at a time, I will start with Football.
I will put equation 1, 2 and 3 into equation 4
3Sw + 2L + L + L = 434
We can now again put equation 1 into the new equation 4
3L + 2L + L + L = 434
Simplify
7L = 434
L = 434 ÷ 7
L = 62 students
Since L = Sw, 62 students did swimming also
We can put L into equation 2 to solve for So
So = 2 * 62
So = 124 students
And now we can put Sw into equation 3 to solve for F
F = 3 * 62
F = 186 students
Answer:
-3/2 u +2 = w
Step-by-step explanation:
-12u + 13= 8w - 3
Add 3 to each side
-12u + 13+3= 8w - 3+3
-12u + 16= 8w
Divide each side by 8
-12u/8 + 16/8= 8w/8
-3/2 u +2 = w
Answer:
1.8 million
Step-by-step explanation:
Add everything up to get 9 million, then divide by 5 to get the average of the years. This leaves you with 1.8 million
