Answer:
What is this Bro
Combine like variables:
(20x^2)(2y^3)
Combine coefficients:
40(x^2)(y^3)
3³
Step-by-step explanation:
Using the rule of exponents
=
Given
= 3³
Answer:x=20/y
x α 1/y
removing the constant of proportionality sign α and replace it with =k
x = k/y
x=10 y=2
10 = k/2
Cross multiply
10x2=k
20=k
k=20
Substitute k=20 in x=k/y
x=20/y.........required equation
S = D/t
D = S×t
D = 80km/h×5h = 400 km
