Jenny is displaying her photographs
Inga [223]

Answer:

A) 9 photos in each row

B) 14 rows in total

Step-by-step explanation:

Photos of People = 45

Photos of Landscapes = 18

Photos of Pets = 63

Jenny wants to arrange these photos in rows with only one kind of photos in each row and same number of photos in each row. We have to find the greatest possible number of photos in each row. For this we need to find the greatest common factor of 45,18 and 63. This would give us the greatest possible number of photos that can be placed in each row.

By observing the 3 numbers, we can tell that the greatest common factor of these 3 numbers is 9. So, Jenny can place 9 photos in each row.

So,

There will be:

45/9 = 5 rows with photos of people

18/9 = 2 rows of photos of landscapes

63/9 = 7 rows of photos of pets

So, total number of rows would be = 5 + 2 + 7 = 14 rows

What is the answer to the equation 5+2(x-1)=12
S_A_V [24]
5+2(x-1)=12 \\ \\ 2 ( x - 1) = 12 - 5 \ / \ subtract \ 5 \ from \ each \ side \\ \\ 2(x - 1) = 7 \ / \ simplify \\ \\ x - 1 =  \frac{7}{2} \ / \ divide \ each \ side \ by \ 2 \\ \\ x =  \frac{7}{2}  + 1 \ / \ add \ 1 \ to \ each \ side \\ \\ x =  \frac{9}{2} \ / \ simplify \\ \\

So, the answer to this problem is x = 9/2 or x = 4.5.

Which estimate best describes the area under the curve in square units?
stepladder [879]
<span>I think any of those estimates are correct since we don't have a value for the width and length so acquiring the actual measurement its impossible. All possible answers are correctly written in square units.</span>
