Let the length of the first piece be x inches. Then:-
x + 2x + 4x + 3 = 38
7x = 38 - 3
x = 35/7 = 5 inches
Answer: the 3 pieces have lengths 5, 10 and 23 inches.
Answer:
y = 120
Step-by-step explanation:
If y = 32 when x = 8, then <em>y</em> is 4 times the number of <em>x</em>. If x = 30, then (4)30 = 120.
The last one is a proportion!

this a non ending one but those should be enough to satisfy a teacher
We shall proceed in graphical method
Graph all 4 functions
Reason:-
It depends upon coefficient
In graph 4 the coefficient outside root is negative so it is decreasing
