Mary is 5 years older than Bob. If the sum of their ages is 39, write and solve an equation to find their ages

Bob is 17 years old

Mary is 22 years old

Step-by-step explanation:

Mary's current age: m

Bob's current age: b

m + b = 39

m = b + 5

Substitute.

b + 5 + b = 39

2b + 5 = 39

2b = 34

b = 17

m = 22

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
