Answer:

First building = 456

Second building = 438

Third building = 383

Step-by-step explanation:

First building = 73 + x

Second building = 55 + x

Third building = x

Total height of three buildings = 1277

(73 + x) + (55 + x) + (x) = 1277

73 + x + 55 + x + x = 1277

128 + x + x + x = 1277

128 + 3x = 1277

3x = 1149

x = 383

This is the height of the third building.

First building = 73 + x = 73 + 383 = 456

Second building = 55 + x = 55 + 383 = 438

Why is it helpful to write numbers in different ways
Goshia [24]
You should write numbers in as many ways as you possibly can to make new connections in your brain. Knowing how to write numbers in many different ways can help you solve complex problems more easily. Doing this can also reinforce the mathematical principles and logic you have memorised.

Writing one in many different ways:

1=1/1=2/2=3/3=4/4=(-1)/(-1)=(-2)/(-2)

=1.0=1.00=1.000=(1/2)+(1/2)=(1/3)+(1/3)+(1/3)

=(1/4)+(1/4)+(1/4)+(1/4)

Writing a half in many different ways:

1/2=(1/4)+(1/4)=(1/6)+(1/6)+(1/6)

=(1/8)+(1/8)+(1/8)+(1/8)=4*(1/8)

=2/4=3/6=4/8=5/10=0.5=0.50

etc...etc...
