Yolanda uses 69 milliliters of solution B to make the mixture.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
Let x represent the amount of solution A and y represent the amount of alcohol B, hence:
x + y = 92 (1)
Also:
y = 3x (2)
From both equations:
x = 23, y = 69
Yolanda uses 69 milliliters of solution B to make the mixture.

Answer:
= x^4 y^5 / 3
Step-by-step explanation:
I got this answer = x^4 y^5 / 3
But my answer is not found directly
And I think they deliberately set up this arrangement to make us mess up
, but in your Options I think it's ( B )
25 over 100 as a percent is 25% and 25 over 100 as a decimal is .25
Answer:
Step-by-step explanation:
Let
x ----> the average depth of the resulting layers of ash and rock
we know that
To find out the average depth, divide the cubic kilometers of molten rock by the area where all the ejected material fell.
so
Convert to meters
Remember that
so
Convert to mixed number
-10c+70, just distribute the the -10 to everything in the expression
