A city skyscraper is 1,450 feet tall. A scale model is made that is 1:290 of its size. How tall is the model?

Height of skyscraper's model = 5 feet

Step-by-step explanation:

Given:

Height of skyscraper = 1,450 feet

Scale model ratio = 1:290

Find:

Height of skyscraper's model.

Computation:

Height of skyscraper's model = Height of skyscraper × Scale model ratio

Height of skyscraper's model = 1,450 × (1/290)

Height of skyscraper's model = 5 feet

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

47 - 90 = 43

43 - 180 = x

x = 137
