Answer:
x = 1
Step-by-step explanation:
You can work this several ways.
1) Consider the factor that gets you from the y-value of the known pair to the y-value of the unknown pair. Here, that factor is -6/12 = -1/2.
Then the unknown value of x is the known value multiplied by that same factor:
x = (-1/2)(-2)
x = 1

2) You can write the equation for a "varies directly" relationship and solve for the constant of proportionality. Then you can use that equation to find the unknown value of x.
y = kx . . . . . . . . . . . . . . y varies directly with x
k = y/x = 12/-2 = -6
Now we know ...
y = -6x
Filling in the new value for y, we have ...
-6 = -6x
1 = x . . . . . . divide by -6
__
3) You can write a proportion. Since we want to find a value for x, it is convenient to put that in the numerator.
-2/12 = x/-6
Multiplying by -6, we get ...
(-6)(-2)/12 = x = 1

You have to seperate the inequalities into 2 :
Then you have to solve it :
Answer:
18 is the number that would go in the green box 33/3 =11 and 54/3 = 18
9 cm
Explanation:
15 squared - 12 squared = the missing side squared.
225-144=81
The square root of 81 is 9
