I'm guessing the % of syrup refers to the % of sugar it has, therefore:
50% = 50 / 100 = 0.5
0.5 * x = 0.5
x = 0.5/0.5
x = 1
She will have 1 lbs of syrup
Answer:
I would say store B.
Step-by-step explanation:
Answer: [B]: " (-6, 9) " .
_______________________________
Explanation:
_______________________________________
Given the following system of equations:
_______________________________________
x + y = 3 ;
y = 9 ;
_________________________________
Substitute "9" for "y" in the first equation; to solve for "x"; we already have our value for "y" ; "y = 9 " ; (given) ;
____________________________
x + 9 = 3 ;
Subtract "9" from EACH side of the equation;
_____________________________________
x + 9 − 9 = 3 − 9 ;
to get:
_____________________________________
x = -6 .
_____________________________________
Check our answer:
x + y = 3
________________
-6 + 9 =? 3 ? Yes!
_____________________
The answer for the system of equations is:
_____________________________________
x = -6, y = 9 ; or, write as: (-6, 9) .
_____________________________________
which is: Answer choice: [B]: " (-6, 9) " .

By looking at it, I can tell the second expression is greater due to a a large postive number that's being added to it. Let's solve.
-12+6=-6-4=-10
-34-3=-37+39=2
So, -34-3+39 is greater.
