Answer:
mean= sum of the terms/ (over) number of terms
Answer:
13
Step-by-step explanation:
x/20 = 65%/100
20 x 65 = 1300
1300 divided by 100 = 13
We have that
<span>If (5x-4+13x=5) --------------> then x=1/2
Step 1
</span>let's substitute the value of x = (1/2) in the expression [5x-4+13x] and verify its result
5*(1/2)-4+13*(1/2)
(5/2)-4+(13/2)
(5-4*2+13)/2----------> (5-8+13)/2=10/2=5
then
5=5-----------> <span>the value of x = (1/2) satisfies equality</span>
