Answer:

1

Step-by-step explanation:

<em>13  15  </em>17  <u>x</u>  <em>20  21</em>

<em>Cross out all outer numbers</em>

We are left with 17 and x

With double medians, you add those two together and then divide them by two.

With the median (total) being 18, we will first add 17+x then divide Y/2 = 18

The value of x is 1

0.9(x+1.4)−2.3+0.1x=1.6
IgorC [24]

so what you do is  distribute the 0.9 to x and 1.4 to get 0.9x+1.26 then combine like terms 1.9x - 1.04= 1.6 then add 1.04 to both sides to get 1.9x = 2.64 divide 1.9 to both sides


answer:1.389 and if you round 1.39
