The value of x = 6
<h3>What is a mixture ?</h3>
A mixture is a combination of two or more elements mixed in a fixed proportion
From the table
It can be determined as
(0.1 + 0.09x ) /(2+x) = 0.08
0.1 +0.09x = 0.16 +0.08x
0.01 x = 0.06
x = 6
Therefore the value of x = 6

You've written "then" before 3, so i assume the real question is:
(40 * 40 * 40 + 26 - 98 + 45 * 78 * 78 * 78) / 3
Use "PEMDAS" first solve under the parenthesis, then after it.
= (64000 + 26 - 98 + 21354840) / 3
= 21418768 / 3
= 7139589.33
In short, Your Answer would be: 7139589.33
Hope this helps!
Hello,
Answer C 9 and 39.
Let a the first and b the second
a=4b+3
a*b=351
==>b*(4b+3)=351
==>4b²+3b-351=0
Δ=9+4*4*351=5625=75²
==>b=(-3-75)/8 =-9.75 ==>a=4*(-9.75)+3=-36 (excluded) a>0
or b=(-3+75)/8=9 and a=4*9+3=39
It will take 2 hours
(1/8)*8=1
(1/4)*8=8/4
8/4=2
