1) -15

2) 5

3) -13

4) -4

5) 5

6) 14

7) 0

8) -8

9) -8

10) 7

These are very easy, when subtracting a negative from a positive think of it as just plain subtraction. When adding a negative to a positive, again, think of it as subtraction. When subtracting two negatives it's basically addition but you final answer should have a negative sign.

Hope I could help! :)

What is the answer to 5 1/2 - 2/3

aniked [119]

To solve this problem, we first have to convert 5 1/2 into an improper fraction. To do this, we multiply the unit (5) times the denominator (2) and then add the numerator (1) to the product, while still keeping the same denominator.

(5 * 2) + 1 = 10 + 1 = 11/2

Now, this makes our expression: 11/2 - 2/3

Next, we have to find a common denominator for 2 and 3 by finding their shared LCM, or least common multiple. In this case, the LCM is 6. This means that we are going to convert both of the fractions in the expression into fractions with the denominator 6, so that we can easily compute the subtraction.

11 * 3 / 2 * 3 - 2 * 2 / 3 * 2

33/6 - 4/6

Now, we can simply subtract the numerators to find our final answer.

29/6

Your final answer is 29/6.

Hope this helps!

We know they combine to 2,977 grams. The puppies weight the same
Let’s make puppy = x
Basket weight = 1,077
8x + 1077 = 2977
8x = 1900, x = 237.5 grams
It would be around 250 grams

Solve for p<br><br> p - 4 = -9+ p

agasfer [191]

P-4 = -9 + p

Because there is the same quantity of the letter p on each side of the equal sign there is no solution to this problem.

Answer: no solution
