Answer: Constant of Proportionality = 12
===================================================
Explanation:
x = number of swimmers
y = number of laps
k = constant of proportionality
k = y/x
Use any row to find that k = 12
- Row1: k = y/x = 240/20 = 12
- Row2: k = y/x = 216/18 = 12
- Row3: k = y/x = 168/14 = 12
- Row4: k = y/x = 108/9 = 12
The direct proportion equation in the form y = kx turns into y = 12x. This means the number of laps is 12 times that of the number of swimmers. Put another way, each swimmer did 12 laps.
Answer:
wk. 1 : 104, wk. 2 : 109, wk.3 : 218
Step-by-step explanation:
x = 1st week, y = 2nd week, z = 3rd week
x + y + z = 431
y = x + 5.........y - 5 = x
z = 2y
(y - 5) + y + 2y = 431
4y - 5 = 431
4y = 431 + 5
4y = 436
y = 436/4
y = 109 <==== week 2
z = 2y
z = 2(109)
z = 218 <==== week 3
x = y - 5
x = 109 - 5
x = 104 <==== week 1
