Answer:
x = 270 gallons
270 gallons of a 50% antifreeze solution must be mixed with 90 gallons of 10% antifreeze to get a mixture that is 40% antifreeze
Step-by-step explanation:
Let x represent the number of gallons of the 50% antifreeze solution.
The volume of the 10% antifreeze is = 90 gallons
The volume of the mixture that is 40% antifreeze = 90+x
The amount of antifreeze in the two solutions must be equal to the amount of anti freeze in the mixture;
50% of x + 10% of 90 = 40% of (90+x)
0.50(x) + 0.10(90) = 0.40(90+x)
0.50x + 9 = 36 + 0.40x
Collecting the like terms;
0.50x - 0.40x = 36-9
0.10x = 27
x = 27/0.10
x = 270 gallons
270 gallons of a 50% antifreeze solution must be mixed with 90 gallons of 10% antifreeze to get a mixture that is 40% antifreeze
Answer:
12.5
Step-by-step explanation:
10, 8, 14, 16, 13, 12
Organize the numbers from least to greatest
8, 10, 12, 13, 14, 16
Normally, the median would just be the number in the middle. However, because there are two numbers in the middle for this data set, add them and divide the sum by 2.
12+13=25
25÷2=12.5
Therefore, the median is 12.5.

<span>The answer is A) y, because Triangle RST is similar to triangle VUT </span>
Reformat the equation to be in terms of y.
4y= 3x-6
y=3/4x -6/4
The y intercept when x=0 is -6/4
The x intercept when y=0 is 2
Simply draw the graph using these two points
Answer:
x=25
Step-by-step explanation:
40 + 3x-5= 5x -5
45 + 3x= 5x-5
+5 +5
50 + 3x= 5x
-3x -3x
50= 2x
/2 /2
25= x
