Kendrick walked 500 m per day, every day for one week. how many kilometers did he walk all together?

3.5

Step-by-step explanation:

500 x 7

3500/1000

3.5

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

yes   because as the functions are graphed they eventually will intersect unless otherwise
