Elvira is 5 years older than Morton. Morton is twice as old as Michelle. The combined total of their ages is 85. How old is Mort

LiRa [457]

Elvira (e) is 5 years older than Morton (m)

e = m + 5

Morton (m) is twice as old as Michelle (c)

m = 2c

The combined total of their ages is 85

e + m + c = 85

We want m at the end so let's write everything in terms of m.

e = m + 5

c = m/2

85 = e + m + c = m+5 + m + m/2 = 5 + (5/2) m

m = (2/5) (85 - 5) = 32

Answer: 32 years old

Check:

That makes Elvira 37 and Michele 16, total 32+37+16=85, good

Zigmanuir [339]

Answer:

The answer is given below

Step-by-step explanation:

Statement Reasons

ABCD is a parallelogram; M is a midpoint Given

of AB and N is a midpoint of Segment

AB//DC, therefore AM//NC For a parallelogram, opposite . sides are parallel to each other

AB≅DC For a parallelogram, opposite . sides are equal to each other

1/2AB≅1/2DC Since both sides are equal to . each other

1/2AB = AM and 1/2DC = NC M is the midpoint of AB and N . is the midpoint of DC Midpoint

. theorem

AM≅NC Substitution, since AB is also

. equal to BC

Quadrilateral AMCN is a parallelogram If opposite sides of a

. quadrilateral is equal and .

opposite, it is a parallelogram
