Kylie is training for an upcoming marathon and has committed to running more than 21 miles today. If she runs from her house, she can run along two loops: a short path that is 3 miles in length, and a long path that is 6 miles in length. Select the inequality in standard form that describes this situation. (x = the number of loops on the short path, y = the number of loops on the long path).

5104.38 inches

step-by-step explanation:

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

the correct answer is a.) bc< mn 5 stars if this you : )

step-by-step explanation:

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
