X+y=8
multiply the first equation by 3 to get rid of x
3x+3y=24
3x+2y=14
subtract equation 1 from 2
y=10
substitute to find the value of x
x+10=8
x=-2

Sam has 2 brothers. His brothers are 5 cm shorter and 7 cm shorter than him. Sam's height is 140 cm. What is the median height o

pochemuha

Answer:

The median height of Sam and his brothers is 135.

Step-by-step explanation:

First, let's find the age of Sam's brothers:

$B_{1} = 140 cm - 5 cm = 135 cm$

$B_{2} = 140 cm - 7 cm = 133 cm$

The median height of Sam and his brothers is given by the middle number of the three values arranged from lowest to highest:

133 <u>135</u> 140

<em>Since the middle number is 135, then the median height is 135. </em>

Therefore, the median height of Sam and his brothers is 135.

I hope it helps you!
