Pythagorean
Theorem as follows: A^2+B^2=C^2
I think it's false because that's not really a proportion.
4:3
3:1
6:2

We want to see if the statement "The relationship among the triple constraint variables is such that if any one changes, at least one other is likely to be affected." is true or false. This is true.
A relationship among the triple constraint variables is written as:
y = f(x, z)
Where the 3 variables are x, y, and z and represent cost, scope, and time.
This means that if either x or z changes, also does y.
And we always can rewrite the relationship in two other forms:
x = g(z, y)
z = h(x, y)
Then we can see that always that one variable changes, at least one other variable changes in response, then the statement is true.

Answer:
4. x=10
5. x=15
6. x=20
7. x=4
Step-by-step explanation:
4. 50+4x=90
90-50=40
40/4=10
x=10
5. (2x+60)+6x=180
6x+2x=8x
8x+60=180
180-60=120
8x=120
120/8=15
x=15
6. 3x+30=90
90-30=60
60/3=20
x=20
7. (8x+120)+7x=180
8x+7x=15x
15x+120=180
180-120=60
15x=60
60/15=4
x=4
