Jill , meg and beth are sisters. jill is 2 yrs younger than meg . beth is half as old as meg . let m represent megs age. write two other algebraic expressions based on this situation . tell what expression represents, and what the variable stands for in each sentence

The algebraic expressions are

x = m + 2

Step-by-step explanation:

As given

Jill , meg and Beth are sisters.

Let m is represented the age of the meg.

Let x is represented the age of the jill.

Let y is represented the age of the Beth.

As given

Jill is 2 yrs younger than meg .

Thus

x = m + 2

As given

Beth is half as old as meg.

Thus

Therefore the algebraic expression are

x = m + 2

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
