Answer:
Brandon is correct.
Step-by-step explanation:
Initially, there id 4 pints of green paint in the bucket.
As the green paint is made from equal amounts of yellow paint and blue paint, so, the initial amount of yellow and blue paint in the bucket is 2 pint each.
Let x pints of yellow paint to be added to the bucket to make the desired shade.
Total amount of the paint in the bucket, after addition of
pints of yellow color become
pint, in which the ampunt of yellow color is
pints.
As, the ampunt of yellow color is 80% of the total amount of the mixture, so




So, 6 pints of yellow paint to be added to the bucket to make the desired shade.
Hence, Brandon is correct.
Solve the system using substitutions:

x has a value of 1. Use this value to find the value of y.

y has a value of 1.
x=1
y=1
Answer: The word "ensures" implies that it is certain.
In the case of the study, they simply found that the average salary is greater for college graduates. This doesn't mean that in every case the college graduate makes more money.
The problem is the word "ensures". Our study doesn't show certainty only a general pattern.
Try this option:
if x+y=-9 is I (one)
and x+2y=-25 is II (two), then
if II-I, then (x+2y)-(x+y)=-25+9 ⇔ y=-16.
