One block tower measures 89/100 meters tall another tower measures 7/10 meters tall what expression can be used to find the height of both towers

height of both tower = 89/100 + 7/10

or

height of both tower = 0.89 + 0.7

Step-by-step explanation:

The first block tower measures 89/100 meters tall .Another tower measures 7/10 meters tall. The expression that can be use to find the height of both tower can be device as follows.

Assuming the height of  the first tower is x meters and the height of the second tower is y meters. The height of both tower  can be expressed as

height of both tower = x + y .

The sum of their individual height will result to the expression of both height of the tower. In our case where we are given the individual height of the towers as 89/100 meters and 7/10 meters, the height of both tower can be expressed as  

height of both tower = 89/100 + 7/10

height of both tower = 0.89 + 0.7

The height of both tower can be further expressed as

height of both tower = 89 + 70/100 = 159/100

height of both tower = 159/100 m or 1.59 m
