y = 3
</span>-2x + 3y =-1
-2x + 3(3) =-1
<span>-2x + 9 = -1

x = 2
answer
x = 2 and y = 3 or (2,3)

I'm guessing the % of syrup refers to the % of sugar it has, therefore:
20% = 20 / 100 = 0.2
0.2 * x = 0.5
x = 0.5/0.2
x = 2.5
She will have 2.5 lbs of syrup
Answer:
m∠I = 58.4°
Step-by-step explanation:
cos = adjacent side/hypotenuse
It is always helpful to have a picture. In your case KI is adjacent to ∠I and IJ is the hypotenuse.
So cos I = KI/IJ = 4.5/8.6
arccos (4.5/8.6) = m∠I
m∠I = 58.4°
It is necessary for you to memorize the definitions of the trig functions in order to do these types of problems. OK?
