The local park has 4 bike racks. each bike rack can hold 15 bikes. there are 16 bikes in the bike racks. what expression shows the total number of empty spaces in the bike racks

answer ---> y =15×4-16

15×4=60

60-16=44

44 spaces remain

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
