Answer: 1/12
Step-by-step explanation:
2/5x-4=8-3/5x.
We want to tank x out of the denominator by multiplying x on both sides.
2/5-4x=8x-3/5
Now we simplify
-12x=-1
x=1/12
Put x in the equation to check it
Answer:
x= 12
Step-by-step explanation:
2x-20=40-3x multiply both sides of the equation by 5
2x+3x= 40+20 move the terms
5x= 40+20 collect like terms
5x = 60 add the numbers
5x= 60 divide both sides by 5
x=12

What is the Rise Run and Slope
Answers
Answer:
Rise = 2
Run = 1
Slope = 2
Step-by-step explanation:
To find the rise you look at how much the line rises, so you can see it rises 2 after going over 1. So now we know the rise is 2 and the run is 1, because we used 1 as the run to find the rise.
The slope is found by dividing the run from the rise
[tex] \frac{rise}{run} [/tex]
So the slope is 2.
Dominic wants to test if one of two types of fertilizer (a standard fertilizer and a new product) is better for producing melons of equal weight after a three-month fertilization program. Dominic has two identical land plots (1 and 2) and is considering how to assign 30 melon plants, each of which has a numbered tag, to the fertilizer. What is the best way to do this as a matched-pairs design?
A. Put all the odd-numbered melons in plot 1 and the even-numbered melons in plot 2. Then give the standard fertilizer to plot 1 and the new product to plot 2.
B. Assign the melons completely at random to the two plots using a coin flip, heads meaning plot 1 and tails meaning plot 2. Then give the standard fertilizer to plot 1 and the new product to plot 2.
C. Obtain pairs of melon plants whose seedling heights are roughly equal at the start of the experiment and randomly assign one of the pair to plot 1 and the other to plot 2. Then give the standard fertilizer to plot 1 and the new product to plot 2.
D. Obtain pairs of melon plants whose seedling heights are roughly equal at the start of the experiment and put the taller of each pair into plot 2. Then give the standard fertilizer to plot 1 and the new product to plot 2.
E. Divide the 30 melon plants into two groups, with the 15 tallest seedlings in one group. Randomly choose which plot to assign the tallest plants and assign the smallest plants to the other plot. Then give the standard fertilizer to plot 1 and the new product to plot 2.
Answers
Answer:
C
Step-by-step explanation:
A. is wrong because having a different height for each seedling and not trying to keep it equal is simply worse than making sure the heights are identical.
B. Completely wrong because it would likely result in 1 plot having more melon seedlings than the other.
C. Correct because it makes sure the seedlings are the same height at the beginning of the experiment, allowing less randomness in the experiment.
D. Putting the taller of a each pair for 1 plot makes it the experiment rigged in favor of the plot with taller seedlings
E. Same issue as D.
5 pounds of apples cost $12. How many pounds of apples can you buy for $1.
Answers
Answer:
5/12 or 0.41666667 pound
Step-by-step explanation:
Set up the equation as 5/12=x/1 and cross multiply. Then you will get 12x=5. Divide both sides by 12 and then you will get 5/12.
Answer:
5/12 of a pound or 0.42 pounds
Step-by-step explanation:
$1 is 12 times less than $12. So, if the amount of money is divided by 12, than the amount of apples you can buy is also divided by 12:
5/12 = 0.42
You can buy 5/12 of a pound or approximately 0.42 pounds of apples for $1.

Answer:
2
Step-by-step explanation:
Put the equation into y = mx + b form, where m is the slope of the line
Distribute 2 to the parentheses:

y + 3 = 2x - 4
Subtract 3 from both sides:
y = 2x - 7
So, the slope is 2.

10 CDs costs $2.30. A package of 50 CDs costs $10.50. Which is the better buy?
Answers
To get the answer to this question we would have to calculate how much each DVD costs in each scenario.
To do this we will divide each cost by the total number of CDS:
[tex]\frac{2.30}{10} = .23[/tex]
[tex]\frac{10.50}{50} = .21[/tex]
For the pack of 10 CDS each CD costs 23 cents. On the contrary, for the pack of 50 CDs each CD costs 21 cents. Therefore to get a better deal, you would want to go with the 50 CDs.
Hope this helps!
- Kay
The cost per CD is lower when buying the package of 50 CDs, it is the better buy. You would save money by purchasing the package of 50 CDs for $10.50.
To determine which is the better buy, we need to compare the cost per CD in both scenarios.
Let's first calculate the cost per CD when buying 10 CDs:
Cost for 10 CDs = $2.30
Cost per CD = $2.30 / 10 CDs = $0.23 per CD
Now, let's calculate the cost per CD when buying a package of 50 CDs:
Cost for 50 CDs = $10.50
Cost per CD = $10.50 / 50 CDs = $0.21 per CD
Comparing the two options:
- Buying 10 CDs individually costs $0.23 per CD.
- Buying a package of 50 CDs costs $0.21 per CD.

Puzzle Details
Elevator Mishap
Six people, whose names are Fred Alberts, Larry Smith, Brian Martin, Marty Jones, Bill Edison, and John Fox were in an elevator together.
Suddenly, the lights went out. When the lights came back on, Fred Alberts' wallet was missing.
Detectives have investigated. They have questioned the suspects, the witnesses, and people who know the suspects. They have collected physical evidence (hair samples, fibre samples, etc.) from the crime scene. They have collected 14 clues, but have not been able to solve the crime.
Therefore, they have called in the world's greatest detective, YOU. You must now examine the clues and solve the crime.
No two suspects have the same weight, colour shoes, colour umbrella, colour car, or hair colour.
The suspect who owns a purple car was wearing tan shoes.
The suspect who weighs 180 pounds owns a green car.
Brian Martin owns a green car.
The suspect who owns a black car was wearing blue shoes.
The suspect who weighs 150 pounds was wearing tan shoes.
Marty Jones was carrying a purple umbrella.
John Fox has red hair.
Larry Smith weighs 210 pounds.
The suspect who weighs 190 pounds was wearing blue shoes.
The suspect who was carrying a red umbrella is not the one who was wearing black shoes.
The thief owns a black car.
The suspect who owns a white car is not the one who weighs 170 pounds.
Bill Edison was wearing brown shoes.
The suspect who weighs 190 pounds is not the one who has red hair.
Answer:
Marty Jones
Explanation:
Given that no two suspects have the same weight, colour shoes, colour umbrella, colour car, or hair colour.
There are six people in the elevator including Fred Albert. Fred Albert was the one whose wallet was stolen and so our suspects are the other five people in the elevator.
We know that the thief owns a black car and he was wearing blue shoes
( since the suspect who owns a black car was wearing blue shoes). The thief also weighs 190 pounds( since the suspect who weighs 190 pounds was wearing blue shoes)
Brian Martin has a green car so he is cancelled out
John Fox has red hair and is cancelled out(since the suspect who weighs 190 pounds is not the one who has red hair)
Bill Edison was wearing brown shoes so he is cancelled out(since thief was wearing blue shoes)
Larry Smith weighs 210 pounds and he is cancelled out( since thief weighs 190 pounds)
We are left with one suspect remaining Marty Jones, hence he is the thief
