Answer:
The constant of proportionality in this case would be 4
Step-by-step explanation:
To find the constant of proportionality, you need to solve for y. Then use the coefficient of x as k, which is the constant of proportionality.
6y = 24x
y = 4x
Answer:
Step-by-step explanation:
g(r) = 0 ⇒ 
⇒r=
và r=
If it takes 10 hours for 9 workers to mow 45 lawns, dividing the 45 lawns by 9 we see that in 10 hours one worker can mow 5 lawns. This means that in one hour, a single worker can mow 5/10=1/2 of a lawn
let
x---------> Aviva’s age
y--------->Kanti’s age
z--------> Lakshmi’s age
we know that
y=x-3-----> equation 1
z=2*y-----> equation 2
substitute equation 1 in equation 2
z=2*(x-3)
so
Aviva’s age------> x
Kanti’s age-------> x-3
Lakshmi’s age----> 2*(x-3)
therefore
the answer is the option
b) 2(x-3)
