Answer:

9

Step-by-step explanation:

The ratio of 5 to 5+3 is equivalent to the ratio of 15 to 15+x. This is because when you have a triangle inside of a triangle and both of them share two of the same sides and the third sides are parallel to each other, the side ratios of the triangles are always proportionate.

\frac{5}{5+3} =\frac{15}{15+x}   Starting equation

\frac{5}{8} =\frac{15}{15+x}   Simplify

5(15+x)=8*(15)   Cross multiply

75+5x=120   Distributive Property on left and simplify on right

5x=45   Isolate the variable

x=9   Divide both sides by 5 (Division Property of Equality)

If I remember right, each column can only go up to 60. so add up to seconds, anything over 60 stays and 1 carries over to the minutes. add those up, anything over 60 stays, and 1 carries over to degrees. then add those.

I got 53° 27' 5"

First, determine if the boundary line should be dotted or solid. In this case, it should be dotted because the symbol is less than not less than or equal to. This leaves you with options B or D. Now, to see if it should be shaded up or down, test it by substituting any point, let's say the origin (0,0), to see if that point is a solution to the equation. If it is, you shade that side of the graph, but if it's not, you shade the other side of the graph.

0 is less than (-3/4)(0) + 2

0 is less than 2.

Because 0 is actually less than 2, the statement is correct and you shade below the line

Answer: D
