Answer:
About 1.5873 ounces of sodium chloride is needed.
Step-by-step explanation:
Here, the amount of sodium chloride needed = 45 grams
Now, by the conversion of units, we know
1 gram = 0.0352739619 ounce
⇒ 45 grams = 45 x 0.0352739619 ounce = 1.5873 ounces
Hence, about 1.5873 ounces of sodium chloride is needed.
First solve the equation for 3x
-3x+3y=12
3x=-57-6y
Now substitute the given value into the equation
-(-57-6y)+3y=12
Then solve for y
Y=-5
Then substitute the given value of y
3x=-57-6✖️(-5)
Now solve for x
X=-9
Ordered pairs
(X,Y)=(-9,-5)
Then you are left with your answer:
(-9,-5)
