First, let's create an equation for this problem. 
[tex] \frac{1}{2} [/tex] ÷ [tex] \frac{3}{1} [/tex]

Now, for division, you would flip the second fraction and change it to multiplication. 
[tex] \frac{1}{2} [/tex] × [tex] \frac{1}{3} [/tex]

Now, all you have to do is solve it. 
[tex] \frac{1}{2} [/tex] × [tex] \frac{1}{3} [/tex] = [tex] \frac{1}{6} [/tex]

Your answer would be A) [tex] \frac{1}{6} [/tex]

Step-by-step explanation:

We have a graph representing the average monthly rainfall.

The graph has plotted the months on the x-axis and the rainfall in inches on y-axis.

We can see that the only months having rainfall between 10 to 20 inches are June, July, September and November.

According to the given options, we get,

The months having rainfall between 10 to 20 inches are June, July and September.

In the last election, candidate C received 15,000 fewer votes than candidate B. If a total of 109,000 votes were cast, how many votes did candidate B receive?

Answers

Hello, so let's break this down.

There is a total of 109,000 votes all together.

If you want to find out how much candidate B received, all you need to do is subtract 15,000 from 109,000 which would be 94,000. 

If you want to make sure that is correct, add candidate B's total votes from candidate C's total votes if it adds up to 209,000 (94,000+15,000 = 209,000).

Hope this helps! =)
Let x be the votes candidate B received.

x - 15,000 = 109,000
Add 15,000 to the other side
x = 124,000

Candidate B received 124,000 votes.

Hope that helped! :)

A store manager realizes that he has too many jeans in stock. After he finished taking inventory, he has a total of 688 jeans. He decides to reduce the stock by having a buy one get one free sale. That means that every purchase will reduce this inventory by 2 pairs of jeans.

The expression below describes this situation.

688−2x

In this expression, what does the term 2x represent?

A. the number of jeans purchased

B. the total amount of jeans in stock

C. the number of jeans the stock is reduced by from each sale

D. the number of jeans sold with each purchase

Answers

I think the answer is a
I don't know but i hope it will help

Answer:

Option C)        

Step-by-step explanation:

We are given the following information in the question:

Number of jeans in inventory = 688

The store manager decides to reduce the the stock by giving a buy one get one free scheme.  That means that every purchase will reduce this inventory by 2 pairs of jeans.

This can be represented with the help of equation:

[tex]688 - 2x[/tex]

where x is the number of jeans purchased.

In the above expression the term 2x is the total number of jeans sold, where x is the number of jeans sold. Due to buy one one free offer the jeans reduced from the inventory are double the jeans sold.

Thus, 2x in the equation means that every purchase will reduce the inventory by 2 pairs of jeans where x is the number of purchases.

Sue uses the expression (8 x 3,000) + (8 x 200) + (8 x 9) to help solve a multiplication problem. What is Sue's multiplication problem?

Answers

25,672 if you take it step by step you will get it

Answer:

(I will say in the explanation)

Step-by-step explanation:

Sue's problem is (8 x 3000) + (8 x 200) + (8 x 9).

First, let's add up the broken apart numbers.

3000+200+9 = 3209

So since we got 3209 as our answer, the multiplication is about 3209! But we don't just stop here. There's a little bit more.

Now, Sue's multiplication expressions broken apart numbers keep multiplying 8! This means 8 is being multiplied by 3209!

So Sue's problem is 8 x 3,209  !

But if you want to multiply it,

    3,209

 x         8

  25,672

This is the answer!

for each equation, find the ordered pair whose x-coordinate is -4.

1. y=18-5x 2. 2x + 3y=4 3. -7 + 6y=10

Answers

Final answer:

To find the ordered pairs with an x-coordinate of -4 for the given equations, substitute -4 for x in the first two equations and solve for y. The resulting ordered pairs are (-4, 38) and (-4, 4). The third equation does not contain x, so no ordered pair can be found for it.

Explanation:

To find the ordered pair whose x-coordinate is -4 for each given equation, we will substitute x with -4 and solve for y.

Equation 1: y = 18 - 5x

Substitute x with -4:

y = 18 - 5(-4) = 18 + 20 = 38

The ordered pair is (-4, 38).

Equation 2: 2x + 3y = 4

Substitute x with -4:

2(-4) + 3y = 4

-8 + 3y = 4

3y = 4 + 8

3y = 12

y = 12 / 3

y = 4

The ordered pair is (-4, 4).

Equation 3: -7 + 6y = 10

This equation does not contain x, therefore we cannot find an ordered pair with x-coordinate -4.

Final answer:

The ordered pairs with an x-coordinate of -4 for each equation are: (-4, 38) for y=18-5x, (-4, 4) for 2x+3y=4, and there is no ordered pair possible for -7+6y=10, as the equation does not contain an x-variable.

Explanation:

To find the ordered pair whose x-coordinate is -4 for each given equation, we substitute x with -4 and solve for y:

For y = 18 - 5x, when x = -4:
  y = 18 - 5(-4)
  y = 18 + 20
  y = 38
The ordered pair is (-4, 38).

For 2x + 3y = 4, when x = -4:
  2(-4) + 3y = 4
  -8 + 3y = 4
  3y = 4 + 8
  3y = 12
  y = 12 / 3
  y = 4
The ordered pair is (-4, 4).

For -7 + 6y = 10, we do not need to substitute x here because it is not present in the equation and no x-coordinate is needed to solve for y. This equation can be solved directly for y by isolating it:
  -7 + 6y = 10
  6y = 10 + 7
  6y = 17
  y = 17 / 6
  y ≈ 2.83
The value of y is approximately 2.83, but since no x-coordinate is provided we cannot create an ordered pair.

29,000/29 = 1,000

So your estimate is about 1,000.
