Answer:

135 cm

Step-by-step explanation:

Let Jose's height = x

The mean of their heights = 150

Given the Heights:

150cm, 170cm, 140cm, 155cm

The mean is the sum if the heights divided by the number of people

Here :

(150 + 170 + 140 + 155 + x) / 5 = 150

(615 + x) / 5 = 150

615 + x = 750

x = 750 - 615

x = 135 cm

<u>Let's solve this problem step by step</u>

<u />2x+3=4(x-6)    |    Given Equation

2x+3=4x-24     |    Distributive Property of Multiplication over subtraction

3=2x-24             |    Subtraction Property of Equality

27=2x                   |     Subtraction Property of Equality

\frac{27}{2}=x                     |     Division Property of Equality

<em>Definition of each property</em>:

  • <u><em>Distributive Property of Multiplication over subtraction</em></u><em>: it says that the product of a number and the difference of two other numbers is equal to the difference between the products of the distributed number.</em>
  • <u><em>Subtraction Property of Equality</em></u>:<em> if the same value is subtracted from two equal sides, the differences remain the same</em>
  • <u><em>Division Property of Equality</em></u><em>: if the same value is divided from two equal sides, the equation remains the same</em>

<em />

Hope that helps!
