Fiona bought some socks that cost $4. 95 for each pair and some belts that cost $6. 55 each. Fiona spent $27. 95 in all. Let a represent the number of pairs of socks purchased and b the number of belts purchased. Which equation models the situation? a plus b equals 11. 50 a plus b equals 27. 95 4. 95 a plus 6. 55 b equals 27. 95 6. 55 a plus 4. 95 b equals 27. 95.

seems like d

step-by-step explanation:

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)

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
