Answer 2

Answer:
Can you solve it if I write the same thing like this ?

   s + 12
   3s -    8
=========

The piece on the left is
      s
      3s
    ====
          4s .

The piece on the right is
   12
      - 8
      ====
   4 .

Write the pieces together again, and you have

   4s + 4

You find that the product of 67 and 5 is 335. How can you use addition to check if you are correct? How can you use division to check if you are correct?

Answers

Answer: Well, there is two ways for addition and two ways for division. either Add 67 5 times (67 + 67 + 67 + 67+ 67) to get 335 or add 5 67 times (5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 etc.) to get 335, And for division (my favorite part) Either get 335 and see if 67 can be multiplied to get 3, 33, or 335. and if either 3, 33, or 335 is to big subtract what you get when you multiply (Enter Number) with 67 to get anything remotely close to 3, 33, or 335. (NOT MORE THAN 3, 33, OR 335 ONLY EXACT OR LESS THAN) or do the exact same with 5.

There are 169 chairs in the gymnasium that need to be arranged in rows and columns. How can they be divided so that there are an equal amount of rows and columns?

Answers

By arranging the chairs in a 13x13 grid, it can achieve an equal number of rows and columns.

To divide the 169 chairs in the gymnasium into an equal amount of rows and columns, we need to find two factors of 169 that are as close to each other as possible.

The factors of 169 are 1, 13, and 169.

The closest factors are 13 and 13, which means we can arrange the chairs in 13 rows and 13 columns to have an equal amount of chairs in each row and column.

Thus, by arranging the chairs in a 13x13 grid, it can achieve an equal number of rows and columns.

How to solve -7=-11+v/5?

Answers

-7 = -11 + v/5
-7 = v/5 - 11
-7 + 11 = v/5
4 = v/5
4 × 5 = v
v = 20

The answer is: v = 20.

add -24 to -11 to get -35 then divide -35 by 5 to get -7

7^3 times 7^-7 times 7

Answers

Hello there! :)

Answer: $(1)/(343)$

*The answer must have a fraction.*

Step-by-step explanation:

Lesson: Zero and Negative Exponents.

Distributive property: a(b+c)=ab+ac

First, you apply exponent rule.

$a^b*a^c=a^b^+^c$

$7^-^3$

$(1)/(7^3)=7^3=7*7*7=343$

Final answer: $(1)/(343)$

Hope this helps!

Thanks!

Have a great day!

Answer:

The answer is 1/343

Step-by-step explanation:

How can you tell 7/10 is greater than 1/2

Answers

Method 1 (Intuitive method):
The simplest method to know how 7/10 is greater than 1/2 is to familiarize yourself with the division operation. For example:

If we have the following rational number: 8/4, the division tells us how many 4s are needed to make 8. In this case, there are 2 fours needed to make 8.

Likewise:
7/10: There are 0.7 tens needed to make 7 as 0.7*10 = 7.
1/2: There are 0.5 twos needed to make 1 as 0.5*2 = 1.

It means that 0.7 > 0.5; therefore, 7/10 > 1/2.

Method 2:
1/2 can be represented as 5/10.

Now if we compare 5/10 with 7/10, we can see that 0.5 is less than 0.7. Hence 7/10 is greater than 1/2.

Answer:

Multiply 1/2 by 5 to get the same denominator, which would equal 5/10
