i dont know if this is what you want? let me know if this helps if not sorry :(

Step-by-step explanation:

Addition 2) The commutative property is true even when there are more than two numbers being added. For example, <em><u>10 + 20 + 30 + 40 = 100</u></em>, and <u><em>40 + 30 + 20 + 10 is also equal to 100</em></u>.

Multiplication 2) Commutative property of multiplication: Changing the order of factors does not change the product. For example,  4 × 3 = 3 × 4 4 \times 3 = 3 \times 4 4×3=3×44, times, 3, equals, 3, times, 4.

Addition 3) The associative property of addition states that the grouping of numbers doesn't change their sum. For example, <u><em>(75 + 81) + 34 = 156 + 34 = 190; and 75 + (81 + 34) = 75 + 115 = 190.</em></u> The sum of both the sides is <em><u>190</u></em>.

Multiplication 3) The associative property of multiplication states that the product of three or more numbers remains the same regardless of how the numbers are grouped. For example, <em><u>3 × (5 × 6) = (3 × 5) × 6.</u></em>

Addition 4)  An example of the additive identity property of addition is <em><u>8 + 0 = 8. </u></em>This shows that when zero is added to a number, the sum is the number itself.

Multiplication 4)  The identity property of 1 says that any number multiplied by 1 keeps its identity. In other words, any number multiplied by 1 stays the same. The reason the number stays the same is because multiplying by 1 means we have 1 copy of the number. For example, <em><u>32x1=32.</u></em>

          Additive Inverse of Addition 5)   Additive inverse is what number you add to a given number to make the sum zero. For example, if we take the number 3 and add -3 to it, the result is zero. Hence, the additive inverse of 3 is -3.

          Multiplicative Inverse of Addition 5)   Which is an example of inverse property? Adding a negative and a positive of the same number will equal 0. The Inverse Property of Addition states the following: Adding a number and it's negative version of itself yields 0. In other words, if you add −3+3 or 152+(−152), the answer will always be 0.

           Additive Inverse of Multiplication 5) a+(−a)=0−a is the additive inverse of a. a + ( − a ) = 0 − a is the additive inverse of a . Inverse Property of Multiplication for any real number a≠0 a ≠ 0 , a⋅1a=11ais the multiplicative inverse of a.

          Multiplicative Inverse of Multiplication 5) The inverse property of multiplication states that if you multiply a number by its reciprocal, also called the multiplicative inverse, the product will be 1. (a/b)*(b/a)=1.

Addition 6) The additive property of zero states that when you have any number and add zero to it, your answer will always equal the original number. In our reading example, you took 40 and added 0. When you did this, you got 40, the original number.

Multiplication 6) The multiplication property of zero is about multiplying 0. ... Multiply a number by 0, you go right to the middle of the number line. Let's look at some examples. 3×0=0 −5×0=0 We conclude that x×0=0.

Margarita [4]

2x - 5 > 7      |add 5 to both sides

2x > 12     |divide both sides by 2

x > 6

If 27% of the group voted to change its
liubo4ka [24]

Answer:

243 people did not vote

Step-by-step explanation:

First you would calculate the number of people who DID vote:

27% + 43% = 70% (this is how many people voted)

you would then subtract to find the percent of people who DIDNT vote:

100% - 70% = 30%

Finally you would convert the % into an actual number.

0.30 (or 30%) x 810 members = 243 members

So, 243 members didn't vote.

Hope this helps!

Write an equation for the following:
inysia [295]

Answer: 3(x+4)=x+18

Step-by-step explanation: Break down the problem. It says three times the sum of a number and 4. You have to add the number and 4 first. Since you're multiplying by 3, put the sum of a number and 4 in parentheses. This equals the same as eighteen more than the number. It set up how it sounds. Add 18 to the number.
