-2/3y - 3/4=5 I am very confused

Answers

-2/3y - 3/4 = 5

Add 3/4 to both sides.

-2/3y = 5 + 3/4

Simplify.

-2/3y = 5 3/4

Multiply both sides by -3/2.

-3/2 × -2/3y = 5 3/4 × -3/2

Simplify.

y = 23/4 × -3/2

Simplify.

y = -69/8 AND y = -8 5/9

One package of fruit drink contains 6 drinks. Which of the following list the ordered pairs (packages, number of drinks) for 1, 2, 3, and 4 packages of fruit drinks?

Answers

I think this is 

(1,6), (2,12), (3,18), (4,24)

1 package has 6 drinks so that = (1,6)

 then multiply 6 by the number of packages for total number of drinks

 so you end up with (1,6) (2,12) (3,18) (4,24)

Is the value of the 1 in 1,440,000 10 times as great as the value of the 4 in the hundred thousands place?

Answers

If you multiply 400,000 by 10 you get 4,000,000. This means that, yes, the value of the 1 is 10 times the 4 in the hundred thousands place. 
Hope I helped :)
Final answer:

The value of the 1 in the number 1,440,000, which is in the million's place, is 2.5 times greater than the value of the 4 which is in the hundred thousand's place.

Explanation:

The value of the 1 in the number 1,440,000 is in the millions place, thus it represents 1,000,000. The 4 on the other hand, is in the hundred thousands place, and thus represents 400,000. The value of the 1 is therefore not just ten times the value of the 4, but in fact, it is 2.5 times greater.

Here is the process: value of 1 = 1,000,000, value of 4 = 400,000, so 1,000,000 / 400,000 = 2.5. Therefore, the value of 1 is 2.5 times the value of 4.

In albany it is -4°f in chicago it is -14°f‚ in minneapolis it is -11°f‚ and in toronto it is -13°f. in which city is the coldest?

Answers

Chicago because on the number line, the numbers to the left get smaller, and the numbers to the right get bigger. Negatives on the number line are going right, and getting smaller, even though it seems the numbers are getting bigger.
EX: -14,-13, -12,-11,-10...

the largest negative number would be the coldest, so -14 would be the coldest.

Which is the better buy 3 pounds for 8.31 or 5 pounds for 12.95

Answers

answer:

5 pounds for 12.95

explanation:

to solve, find the unit rate. the cheaper unit rate is the best and cheapest choice.

8.31/3 = 2.77
12.95/5 = 2.59

5 pounds for 12.95 is the cheaper choice because it has a smaller unit rate.

Hope this helps! :D
It'd be better to buy the 5 pounds for 12.95.

If you divide the price by the amount, it results as 2.59 as opposed to 3 pounds for 8.31 which is 2.77 per pound, making it clear now that the 5 lb for 12.95 is the better deal
