Answer: 66 miles per hour i belive
Step-by-step explanation: good luck
The lowest I could go was -6x - 9. (Hope that helps)
Total = 36oz
Amount of 18% solution = x
Amount of 9% solution = 36 - x
Using the fact that (amount of solution) * (percent HCl) = amount HCl we can set up an expression for the amount HCl in a mixture of 18% and 9% solutions with a total volume of 36oz.
Amount of HCl = x*0.18 + (36 - x)*0.09
If we divide this by the amount of solution we get percent HCl, and we have a target of 10% HCl. Now we have an equation to solve,
[x*0.18 + (36 - x)*0.09]/36 = 0.1
x*0.09 + 3.24 = 3.6
.09x = 0.36
x = 4
Therefore,
4 ounces of 18% HCl solution and 32 ounces of 9% HCl solution
Check:
[(4*.18) + (.09*32)]/36 = 0.1?
0.1 = 0.1 Yes.
The expression which is equivalent to 6 Superscript 4 times 6 cubed and posses same value as this expression is,

<h3>What is the equivalent expression?</h3>
Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.
The given statement for the expression is 6 Superscript 4 times 6 cubed. This expression cab be written as,

Suppose the equivalent expression of this equation is n. Thus,

The 4 power of number 6 means that the number 6 should be multiplied 4 times.

Hence, the expression which is equivalent to 6 Superscript 4 times 6 cubed and posses same value as this expression is,
