1/3 is greater than 2/7 because if you put them the same denominator in this case it would be 21 you would multiply 1/3 by 7 and 2/7 by 3 so 1/3 would be 7/21 and 2/7 would be 6/21 so yes 1/3 is greater than 2/7
The Pattern B is the twice of the Pattern A. Then the correct option is C.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Item 11 In the table,
Pattern A uses the rule "add 5" and Pattern B uses the rule "add 10".
Pattern A 10 15 20 25 30
Pattern B 20 30 40 50 60
Then the Pattern B is the twice of the Pattern A.
Then the correct option is C.

1. <span>In this case the two </span>equations<span> describe lines that intersect at one particular point. Clearly this point is on both lines, and therefore its coordinates (x, y) </span>will<span> satisfy the </span>equation<span> of either line. Thus the pair (x, y) is the one and only </span>solution<span> to the </span>system of equations<span>.

First divide both sides of the equation by -3, then add 3x to both sides of the equation.
-3x + y = -1
y = 3x + 1
We know that the mixture has 14 mm of ink. Of these, 35% are blue pigment, hence the mixture contains 4.9 mm of blue ink. Ink A contains 10%*4mm=0.4mm of blue ink. The difference, 4.5 mm of blue ink must have come from ink B. Thus ink B contains 4.5 mm of blue ink and is in total 10mm. After that, we can calculate the percentage; we divide 4.5/10=0.45 and this is the ratio of blue ink to total ink (in Ink B). If we transform it to percentages it is 45%
