Answer:
The answer is C
Step-by-step explanation:
x=20
y=10
What you do is plug in x and y in the answers to see what is true
a. 10=20²
b.10=1/3(20)
c. 10=1/2(20)
d. 10=2(20)
Therefore answer is C.
The equation for given question is 20=2(10).
What is an equation?
A equation contains expressions with an equal to sign. For example 3x+4=10, in this equation 3x+4 and 10 are expressions which are connected with equal to sign.
Let t be the proportionality constant.
The relation between x and y is directly proportional so, the equation will be x=ty.
On substituting the given values the equation will become 20=10t.
on solving the equation we have t=2.
On substituting all the value into the equation, the final equation will be 20=2(10).
Therefore, the equation for given scenario is 20=2(10).
