Answer:
z = 0.9778x^2 / y.
Step-by-step explanation:
When z varies with the square of x the equation is z = kx^2 where k = a constant.
If it also varies inversely with y the equation is z = kx^2/y.
When z = 4.4 , x = 3 and y = 2 we have:-
4.4 = k * 3^2 / 2
Multiplying by 2:
8.8 = 9k
k = 8.8 / 9
= 0.9778.
So the required formula is z = 0.9778x^2 / y.
Answer:
B. Add/subtract the same quantity from both sides.
in this case, it would be adding <em>x</em><em> </em>to both sides to simplify the equation.

Step-by-step explanation:
Answer:
The angle measures are;
36,72, 108 and 144
Step-by-step explanation:
Since it is a quadrilateral
the sum of all the interior angles is 360
so, we have that;
4x + x + 3x + 2x = 360
10x = 360
x = 360/10
x = 36
So each of the angles are as follows;
x = 36
4x = 4(36) = 144
3x = 3(36) = 108
2x = 2(36) = 72
