Commutative means that you can mix up the numbers, but still have the right answer.
2 x 10 x 7 =
2 x 7 x 10 =
10 x 2 x 7 =
10 x 7 x 2 =
7 x 2 x 10 =
7 x 10 x 2
Hope this helps :)
Let's say that ST is side b
<span><span>Use the Law of Sines to find side b.</span><span>
b / sin(B) = a / sin(A)</span><span>
b / sin(59°) = 7 / sin(79°)</span><span>
b = (sin(59°) x 7) / sin(79°)</span><span>
b = 6.112
That is answer B.) 6.1 yards
Hope this helps!</span></span>

Answer:
(5/7)m + 2n + 3
Step-by-step explanation:
Rewrite 3/7m as (3/7)m for added clarity, also 2/7m as (2/7)m.
Adding (3/7)m and (2/7)m results in (5/7)m.
Next, combine -3 and 6, which yields 3.
I expected that there'd be only one term in m in both quantities. (3/7)m - 3 + 4n does have only one term, but (2/7)m - 2m + 6) seems to have two m terms. I will assume that you actually meant (2/7)m - 2n + 6).
Combining like terms, we get (5/7)m + 3 + 4n - 2n, or
(5/7)m + 2n + 3
Answer: Choice A
The two characteristics here are:
- The boundary line is a dashed line. This visually indicates to the reader "points on the boundary do NOT count as solutions". Think of the boundary as an electric fence you cannot touch, but can get closer and closer to. We aren't including boundary points directly because of the lack of "or equal to".
- The shading is above the boundary, due to the "greater than" sign. This only works if we have y isolated.
The graph of choice B is
since we have a solid line and shading below the solid line. This time points on the boundary are part of the solution set.
