-2x + 6 = -2x + 6
this problem has infinite solutions :)
Let the base of the ladder be x ft and the extension be y ft.
"when fully extended, a ladder is 28 feet in length."
means: x+y=28
"<span>the extension is 4 feet shorter than the base</span>"
means: y=x-4, that is x-y = 4, (taking y to the side of x, and -4 to the other side of x and y)
thus, we have the system of equations:
1) x+y= 28
2) x-y=4
adding the 2 equations, we have:
(x+y)+(x-y)=28+4
2x=32
x=32/2=16
x+y=28, so 16+y=28, thus y=12
Answer: Base: 16, Extension 12

Step-by-step explanation:
For this case we have that the total daily protein consumption is given by:
Now, we find the percentage corresponding to breakfast:
53g ---------> 100%
17g -----------> x
Where "x" represents the percentage of protein equivalent to breakfast:
Thus, at breakfast approximately 32.08% of the total protein should be consumed.
