For a two-day rental at the surf shop, it costs $45 to rent a surf board and $60 to rent a paddle board. On a certain weekend, t
Vaselesa [24]
X = surf boards, y = paddle boards

x + y = 44......x = 44 - y
45x + 60y = 2265

45(44 - y) + 60y = 2265
1980 - 45y + 60y = 2265
-45y + 60y = 2265 - 1980
15y = 285
y = 285/15
y = 19 <=== there were 19 paddle boards rented

x + y = 44
x + 19 = 44
x = 44 - 19
x = 25......and 25 surf boards rented

What is the value of x?<br><br> Enter your answer in the box.<br><br> x = __ cm
BartSMP [9]

This is a proportionality question.  We have two transversals meeting at a point; the indicated congruent angles indicates the traversals intersecting parallel lines.  Usually in these sorts of questions the parallel lines are on the same side of the common vertex, but here the vertex is in between, so the x is proportional to the 42.

x/6 =42/36

x =  6(42/36) = 42/6 = 7
