Amir arranged 9 photos on a bulletin board. He put the photos in rows. Each row contains the same number of photos. How many photos could be in each row?

Answers

Answer: There will be 3 rows with 3 photos.

Step-by-step explanation:

Since we have given that

Number of photos to be arranged by Amir on a bulletin board = 9

According to question, we have given that each row contains the same number of photos.

Let the number of rows be x

So, the number of photos also be x

So, our equation becomes

$x^2=9\n\nx=√(9)\n\nx=3$

So, there will be 3 rows with 3 photos.

three rows of threes

What are two addition equations that each have a sum of -21.5?

Answers

Final answer:

Two example addition equations resulting in -21.5 could be -10.75 + -10.75 = -21.5 and -30 + 8.5 = -21.5. These illustrate the addition of negative and positive numbers to achieve a negative sum.

Explanation:

Two addition equations that each have a sum of -21.5 could be as follows:

Equation 1:-10.75 + -10.75 = -21.5

In this equation, we're adding two identical numbers (-10.75 and -10.75), which together give us a sum of -21.5.

Equation 2:-30 + 8.5 = -21.5

In this equation, we're adding -30 and 8.5, which together also give us a sum of -21.5. In both cases, we're practicing addition of negative and positive numbers to get a negative sum.
