Answer:
x = 15, UV = 12, SV = 31
Step-by-step explanation:
13 + 6 + (2x - 18) = 4x - 29
2x + 1 = 4x - 29
2x = 30
x = 15
UV = 2x - 18 = 2*15 - 18 = 30 - 18 = 12
SV = 4x - 29 = 4*15 - 29 = 60 - 29 = 31
Answer:
12
Step-by-step explanation:
distribute the 2, turning the equation into 2x+12=36
subtract 12 from both sides, now resulting in 2x=24
then divide by 2
The concentration of solution would be the amount of the molecule divided by the volume. In this case, the solution concentration is 36% and the volume is 4 quarts + 1 quarts= 5 quarts. You are asked the concentration before 1 quarts added. The alcohol content should be same for both solutions. The answer should be:
concentration = alcohol content/ volume
alcohol content =concentration * volume
alcohol content1 =alcohol content2
36% * 5 quarts = concentration2 * 4quarts
concentration2= 36% * 5 quarts / 4 quarts= 45%
Hello!
You can make two expressions based on what you know
2l + 2w = 52
w = l - 2
You can put w in the first equation
2l + 2(l - 2) = 52
Distribute the 2
2l + 2l - 4 = 52
Combine like terms
4l - 4 = 52
Add 4 to both sides
4l = 56
Divide both sides by 4
l = 14
We can put this into the second equation to get the width
w = 14 - 2
w = 12
The length is 14 and the width is 12
Hope this helps!
Yes Jackie would have enough money to buy a CD player. So you would have to do 32.95 times that by 30% (.3) and would get 9.885 which you would round that to 9.89 dollars.
