Answer:

Sometimes

Step-by-step explanation:

SOMETIMES, An integer is less than its opposite and greater than 0.

This is because a negative integer has a positive opposite, hence a negative integer will be less than its opposite.

However, a positive integer also has a negative opposite so it will be greater than its opposite.

For example, a negative integer of -5 is less than a positive integer of 5 which is it's opposite and at the same time, a positive integer of 5 is greater than its opposite which is negative integer of -5.

Also, even though a positive integer is greater than 0, a negative integer on the other hand is less than 0

Jamar's teacher told him that one of the reasons he gave on the proof below was incorrect. Which reason did he make the mistake

Kamila [148]

Answer:

Reason given in step 2. is incorrect. It should read; "Distributive Property."

Step-by-step explanation:

The reason given to go from :

2 (3x +4) = 56 to 6x + 8 = 56

is NOT "Multiplication Property of Equality" because one is not multiplying both sides of the equality by a number. The property that is being used is the Distributive Property on the left side of the equation in order to remove the grouping symbols (parenthesis) performing the implied multiplication of the external factor times each term of the binomial in parenthesis.

Find the missing number:

nirvana33 [79]

Answer:

20%

Step-by-step explanation:

Not sure if this is exactly correct, but let's say we start with 1 unit. If it increased by 25%, we get:

1 × 1.25 = 1.25 units.

Now, to get back to 1 unit, we need to find:

1.25 × ? = 1

? = $\frac{1}{1.25}$ = 0.80

So, 100% - 80 % = 20%

A 20% decrease.

Not completely sure though.
