Isolate the variable by dividing each side by factors that don't contain the variable.
n = 22

so.. .whatever those amounts are, of "x" and "y", for the mixture,
they must add up to 100 grams, or x + y = 100
and the titanium percentage of that sum, must yield a 13 grams of titanium on those 100 grams
thus

do the substitution, and solve for "x",
what's "y" amount? well, y = 100 - x
1/5 of 30 is 6.
There are 6 red circles
Answer:
A.
Step-by-step explanation:

y = mx + b
in your problem m = -1/3
and b which is the y intercept = to 8/3
So A. is the answer
Hope this helps!
