Answer:
1.5gal
Step-by-step explanation:
From the given information:
50% lemon juice + 50% lime juice is the intended mixture.
Therefore, to find quantity that would be added to 20% lemon juice and 80% lime juice, let's assume this to be x.
x of 100% and 4-x gallons of the existing 20% mix
100%x + 20%(4-x) = 50%(4)
1.00x + 0.2(4-x) = 0.5(4)
1.00x + 0.8-0.2x = 2
1.00x-0.2x = 2-0.8
0.8x = 1.2
× = 1.5gal.
5x+x=180
6x=180
x=30
5(30)= 150
One angle is 30 degrees and the other is 150 degrees.
20 because 10 times 2 equal 20
The greatest common factor of all the coefficients is of 8.
<h3>What is the greatest common factor?</h3>
The greatest common factor between multiple terms is the largest value for which all terms are divisible.
In this problem, the equation is:

The terms are 16, 56 and 96. Hence, to find the gcf, we have to keep factoring them by prime factors while all can be factored by the same value, hence:
16 - 56 - 96|2
8 - 28 - 48|2
4 - 14 - 24|2
1 - 7 - 12
There are no terms by which both 7 and 12 are divisible, hence the procedure is stopped and:
gcf(16, 56, 96) = 2³ = 8.
