Simonne used the following steps to simplify the given expression.12 minus 3 (negative 2 x + 4)

Step 1: 12 + (negative 3) (negative 2 x) + (negative 3) (4)
Step 2: 12 + 6 x + (negative 12)
Step 3: 12 + (negative 12) + 6 x
Step 4: 0 + 6 x
Step 5: 6 x

What property of real numbers was used to transition from step 3 to step 4?
identity property of addition
inverse property of addition
associative property of addition
commutative property of addition

Answer 1

Answer:

The property of real numbers that was used to transition from step 3 to step 4 is the identity property of addition.

The steps to simplify the given expression are as follows:

12 - 3 (-2 x + 4)

Step 1: 12 + (-3) (-2 x) + (-3) (4)

Step 2: 12 + 6x + (-12)

Step 3: 12 + (-12) + 6 x

Step 4: 0 + 6 x

Step 5: 6 x

As we know that the identity property of addition states that adding zero to any number does not change the value of that number.

In step 3, we have 12 + (-12), which is equivalent to adding zero to 12.

Therefore, the property used in this transition is the identity property of addition.

Answer 2

Answer:

Answer:

Inverse property of addition

Step-by-step explanation:

The purpose of the inverse property of addition is to get a result of zero. The purpose of the inverse property of multiplication is to get a result of 1. We use inverse properties to solve equations. Inverse Property of Addition says that any number added to its opposite will equal zero.

Answer:

It would be 3:00 am.

Step-by-step explanation:

Start time is given = 2:15 a.m

elapsed time = 45 minutes

After 45 minutes of start time, time is = 02:15 + 00:45

= 03:00 am.

After 45 minutes elapsed time, the time would be 3:00 am.

an item was selling for $72 is reduced to $60 find the precent decrease in price round your answer to the nearest tenth

Answers

Remember this, 5 or higher goes up, 4 or lower the number stays the same. soooo.... lets see how i can start this off...
well,... you could....60 divided by 72 equals.... 0.8333333333333
then, starting from the decimal.. you go two spaces to the right... so thats 83.3333333333
so, since 3 is lower than 4, it would be the same.. and take off the extra three after the decimal. and we're basically... rounding off right??
so your answer should be 80%
Hope i helped!!! :D
