Walt grew 10 centimeters in one year. He is now 1.6 meters tall. How tall was Walt one year ago in centimeters?

One year ago, he had height of 150 cm.

Step-by-step explanation:

We have to model this situation.

The first step is having everything as the same unit. I am going to work in meters initially.

Each m is 100 cm. So 10cm = 10/100 = 0.1m.

I am also going to say that his height one year ago was x.

His height is now 1.6m, which is 10cm = 0.1m above his height last year, which was x. So

His height last year was 1.5m.

In centimeters, that is 1.5*100 = 150 cm.

answer: a rhombus has two lines of symmetry that run through one vertex to the one directly across it. unlike a square, planes through the center of each edge of a rhombus do not yield mirrored sides.

step-by-step explanation:

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
