Please help - 1/2 - 2/3v = 4/5
Answers
Answer and Step-by-step explanation:
First, let's convert all of the denominators to have the same denominator.
A common denominator 2, 3, and 5 share in common is 30.
((-1/2) * 15/15) + ((-2/3 v) * 10/10) = ((4/5) * 6/6)
-15/30 + -20/30v = 24/30
Add 15/30 to both sides.
-20/30v = 39/30
Multiply by -30/20 on both sides to get v.
v = [tex]-\frac{39}{20}[/tex] is the answer.

how many solutions dose 3x+2=2x+2+x have explain why below remember explain
Answers
Answer:
All real numbers are solutions.
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3x+2=2x+2+x
3x+2=(2x+x)+(2)(Combine Like Terms)
3x+2=3x+2
3x+2=3x+2
Step 2: Subtract 3x from both sides.
3x+2−3x=3x+2−3x
2=2
Step 3: Subtract 2 from both sides.
2−2=2−2
0=0

Ratios and Proportions
Algebraic Expressions

Glossary and Links
back to Ratios, Page 1
A proportion is similar to a ratio, except that it indicates a part of a whole, and so the numerator arises from the denominator. For instance, a researcher might say that, for every ten students in the residence hall, five were women. Five over ten (5 / 10) is a proportion. Proportions must have all of the numbers in the same units, and are frequently written as fractions.
What happens when you want to write a proportion, but the numbers are given in different units? Suppose you were asked to write the proportion of 3 cups to 56 ounces (3 cups out of 56 ounces). You must write a proportion of either cups to cups (cups:cups) or ounces to ounces (ounces:ounces), so you will have to convert one of the numbers so that both numbers are expressed in the same unit of measurement. Let's convert cups to ounces so we can express the ratio as ounces:ounces. Since there are 8 ounces in one cup, 3 cups are equal to 24 ounces:
3 cups * 8 ounces/cup = 24 ounces
Now the two numbers 3 cups and 56 ounces can be written as the following ratio:
24 ounces to 56 ounces,
24:56,
or, now that the unit of measurement is the same, 24:56 can also be written as a proportion:
24/56
You may need to solve some problems involving ratios.
If you divided 36 into two parts in the ratio of 1:2 and one part is a and the other is b, you can find the value of a and b:
You know that
a+b = 36
And
a/b = 1/2
You can use these equations to solve for a and b, or you can use the following simple method:
Find out how many units are in 1 part of the ratio. To do this, divide the total by the number of parts.
Number of parts: 1 + 2 = 3.
Number of units in each part: 36/3 = 12.
Then, multiply the number of units in each part by the number of parts in each variable.
a = 1 * 12 = 12
b = 2 * 12 = 24
As an aside . . .
Percentages are so frequently used that we should spend a little time on them here. The powerful thing about percentages is that they all have the same denominator: 100. When two fractions have the same denominator, comparisions can be made very easily.
0.21 = 21% = 21 / 100

1. 343
2. 64
3. 81
4. 12.25
Step-by-step explanation:
Answer:
[tex]7^{3}[/tex] = 343
4 cubed = 64
[tex]9^{2}[/tex] = 81
[tex](3.5)^{2}[/tex] = 12.25
Step-by-step explanation:
[tex]7^{3}[/tex] is the same thing as 7 * 7 * 7.
7 * 7 = 49
49 * 7 = 343
4 cubed can be written as [tex]4^{3}[/tex], which is the same as 4 * 4 * 4.
4 * 4 = 16
16 * 4 = 64
[tex]9^{2}[/tex] is the same as 9 * 9.
9 * 9 = 81
[tex](3.5)^{2}[/tex] is the same as 3.5 * 3.5.
3.5 * 3.5 = 12.25

Alex wants to buy a case of drinks, he doesn’t have enough. The cost of the case is $30. He already has $2. He gets $8 every hour for work. How many hours does he need to work to get the amount he needs? Explain what your solution means in the context of the problem.
Answers
Answer:
Alex will need to work 4 hours.
Step-by-step explanation:
We know that Alex already has $2. This means that to get $30 he now only needs to get $28. If he gets $8 per hour, we know that 8 x 3 = 24, but that isn't enough. In this case, 3 is how many hours he works. Because $24 isn't enough, he needs to work 4 hours to get $32 in order to buy the case. Even though he has more money than he needs, he will be able to buy the case and save some extra money.
Answer:
3.5
Step-by-step explanation:
Wright, an equation first like this,
2+8x=30 because he needs 30 dollars but already has 2 and earns 8 dollars per hour.
Solve:
2 + 8x = 30
30-2= 28
28/8= 3.5 so he would need to work 3.5 hours.

Christel wants to know what the most popular color at her school is. She surveys students grades 1,2,3.
Will the sample be representative or biased? And can you please explain how that answer works. Thx! :)
Answers
Answer:
It will be biased.
Step-by-step explanation:
By surveying only grades 1, 2, and 3, she is not taking a representation of the entire school. It is possible that the popular color or the color the students like would change over time and the opinion of the younger kids could be different from that of the older kids. Therefore, the sample is biased unless she surveys students from all grades.
