In the Lab, Yolanda has two solutions that contain alcohol and is mixing them with each other. She uses 3 times as much Solution A as Solution B. Solution A is 10% alcohol and Solution B is 16% alcohol. How many milliliters of Solution B does she use, if the resulting mixture has 92 milliliters of pure alcohol?
1 answer:
Yolanda uses 69 milliliters of solution B t o make the mixture .
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship b etween two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable i s 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 t o make the mixture .

Answer:
16/24
Step-by-step explanation:
9/12–> simplify to 3/4
3/4=15/20
24/32=3/4
6/8=3/4
16/24 is not equal
Solve your system of equations. 2x+y=1;4x+2y=−1 Solve 2x+y=1 for y: 2x+y+−2x=1+−2x(Add -2x to both sides) y=−2x+1 Substitute (−2x+1) for y in 4x+2y=−1: 4x+2y=−1 4x+2(−2x+1)=−1 2=−1(Simplify both sides of the equation) 2+−2=−1+−2(Add -2 to both sides) 0=−3 Answer: No solution. C)
