What does the next consecutive odd number after
another odd number mean? Thanks

Answers

Answer:

I'm pretty sure its just the next number. So the equation would be n + (n +2) + (n + 4), and for example they might be talking about n. And they want to know the next consecutive odd number, the next one would be (n + 2).

Hope that helps.

1.) - 3/4 x 5/8
2.) - 1/5 x (-2/3)
3.) -81.4 divided by 0.4
4.) -2 1/4 divided by 1 1/2
5.) (-1 1/3)(-2 1/2)
Thank you so much!

Answers

Answer:

1) -15/32

2) 2/15

3) -203.5

4) -3/2 = -1.5

5) 10/3 = 3 1/3

Step-by-step explanation:

For 1, you just multiply the numerators and denominators together (3 by 5, 4 by 8) and then because it is negative, add the negative sign.

For 2, you multiply again, but because there are 2 negative signs, it becomes positive.

For 3, you divide 81.4 by 0.4, you could also divide 814 by 4.

For 4, you keep change flip, so the equation would become -9/4 (-2 1/4=-9/4) and 3/2 would become 2/3. The equation would be (-9/4 * 2/3). Then, you would get -18/12 which is -3/2.

For 5, you just multiply 4/3 by 5/2 which is 20/6 and because 2 negatives, it becomes positive.

1. -15/32

-3/4 TIMES 5/8. So what you are going to do is multiply the bottom number by the top number and remember that a negative times positive equals negative. -3 times 5 equals -15 so that's the top number. Then, do the bottom number and it's 8 times 4, which is 32.

2. 2/15

So you do the same stuff for the last problem but now for this one so -1 times -2 is positive 2 so that's going to be the top number. Then 5 times 3 is 15.

3. -203.5

(-81.4)/0.4. So what you can do is do long division and get -203.5.

4. -1/5

(-2 1/4)/11/2. So what we can do is put the first fraction into improper fractions. So that would be -9/4 DIVIDED by 11/2. So then you're going to multiply 11/2 by 2 and get 22/4. Now we have -9/4 divided by 22/4.

5. 3 1/3

Switch them to improper fractions. -4/3 times -5/2. This will definitely be a positive because of the fact that it's a negative times a negative. This would equal 20/6 which can be simplified to 3 and 1/3.

Here is a double number line showing that it costs $3 to buy 2 bags of rice:

1. At this rate, how many bags of rice can you buy with $12? ___________

2. Find the cost per bag. _____________

3. How much do 20 bags of rice cost? _____________

Answers

Answer:

1. 8 bags of rice

2. $1.50 per bag

3. $30

Step-by-step explanation:

For #1, you set up the proportion 3 over 2 is equal to 12 over x and solve by cross multiplication. Then, you should get the answer of 8 bags. For #2, you do $3 divided by 2 to get the answer of $1.50. For #3, you use your answer from #2 and do 1.5 times 20 to get $30.

1. The cost of 12 bags of rice is 18 dollars.

2. Per bag of rice cots 1.5 dollars.

3. The cost of 20 bags of rice is 30 dollars.

What is a unitary method?

A unitary method is a mathematical technique for determining the value of a single unit then we can derive any no. of units by multiplying it by the single unit.

Given it costs 3 dollars for 2 bags of rice.

We know if we determine the cost of one bag of rice we can find out the cost of any no. bags of rice.

∴ 2 bags of rice cost 3 dollars,

So, 1 bag of rice cots (3/2) dollars = 1.5 dollars.

1. At the rate of 1.5 dollars per bag of rice 12 bags of rice will cost (1.5×12) dollars = 18 dollars.

2. The cost per bag of rice is 1.5 dollars.

3. The cost of 20 bags of rice is (1.5×20) dollars = 30 dollars.

Answer:

33 chairs

Step-by-step explanation:

c= chairs per row

5 rows of (c) chairs plus 3 chairs is equal to 3 rows of (c)chairs plus 15 chairs)

5c +3 = 3c +15

2c=12

c= 6 ( 6 chairs per row)

30+3 = 33

3x6=18
