It's a false statement.

On the left side,  28 - 0.3 = 27.7

On the right side,  0.7 - 12 =  -11.3

The equation says that  27.7  is equal to  -11.3 , but it's not.

The variables y and x have a proportional relationship, and y = 7 when x = 2. What is the value of y when x = 5? Enter your answ
Vsevolod [243]

Answer:

17.5

Step-by-step explanation:

Given that the variables x and y have a proportional relationship.

i.e. y is directly proportional to x or can be written as

y = mx where m is the constant of proportionality.

When x =2, y =7

Substitute this to get the value of m.

7 =2m or m = 3.5

Thus the relationship between x and y is

y = 3.5x

So when x=5, y = 3.5(5) = 17.5
