How can properties help me divide?

The distributive property can help you by allowing you to make smaller, easier divisions from your original quantity.

For example, 176 divided by 8 seems complicated at first. However, by breaking it into smaller pieces via the distributive property, it will be easier to compute.

First, take a smaller number out of 176 that is divisible by 8, like 80. 80 divided by 8 is 10, and you will be left with 96 from the original 176. Another 80 divided by 8 is another 10, and you will be left with 16 from the original 176. 16 divided by 8 is 2. So, now you can add all these results together: 10 + 10 + 2 = 22. 176 divided by 8 is 22.

176/8 = 80/8 + 80/8 + 16/8 = 10 + 10 + 2 = 22.

Help please!!!!!! 12-13 8th grade math!!!

Answer:

12.

m∠ACB = 180° - 58° - 78° = 44°

m∠DCE = 180° - 85° - 60° = 35°

m∠BCD = 180° - 44° - 35° = 101°

13.

Base on the picture, we know that:

x° + 2x° + 3x° = 180°

6x° = 180°

x° = 180° ÷ 6 = 30°

=> m∠K = 2x° = 2 × 30° = 60°

=> m∠L = 3x° = 3 × 30° = 90°

=> m∠KML = x° = 30°

m∠LMN = 60° + 90° = 150°

Evaluate 3x for x = −2, x = 1, and x = 3. Question 18 options: A) 1∕3, 0, 9 B) 1∕9, 3, 27 C) 9, 3, 27 D) 1∕9, 9, 27

icang [17]

Answer: B) 1/9, 3, 27

Step-by-step explanation:

Here, we need to evaluate $3^x$ for $x = -2, x = 1, \text{ and } x = 3.$

So, we substitute values of x in the given function.

At x= -2, we have

$3^{-2}=\dfrac{1}{3^2}=\dfrac{1}{9}\ \ \ [\because\ a^{-n}=\dfrac{1}{a^n}]$

At x= 1, we have

$3^1=3$

At x= 3

$3^3=3\times3\times3=27$

So, the values of $3^x$ for

Thus, the correct answer is B) 1/9, 3, 27

How do I do it, please help.If you do help explain it clearly for me

likoan [24]

First we set up a proportion:

$\frac{3}{4} = \frac{27}{x}$

Now we solve the proportion:

• 27*4 = 108

• 3*x = 4x

• 3x = 108

We solve for X by dividing 3 on both sides:

• 3x/3 = x
<span>• 108/3= 36
</span>
Our answer:

x = 36

There were 36 boys in the club.
