Judy’s brother Sam has a collection of 96 comic books what are the 10 where is Sam could divide his comic books into equal group
sweet-ann [11.9K]

We have been given that Judy’s brother Sam has a collection of 96 comic books. We have been asked to find the 10 ways Sam could divide his comic books into equal groups.

This can be done as follows:

96 can be written as 2\times 48=48\times 2=96. Thus, we can either have 2 groups of 48 comics or 48 groups of 2 comics. As we can see we have 2 ways to divide the comic books in equal groups.

Likewise, 96 can also be written as 3\times 32=32\times 3=96. Here, we can similarly see that we can either have 3 groups of 32 comics or 32 groups of 3 comics. As we can again see we have 2 more ways to divide the comic books in equal groups, taking the total number of ways to 4.

Continuing in this manner we will see that we can have 4 groups of 24 or 24 groups of 4, 6 groups of 16 or 16 groups of 6 and lastly 12 groups of 8 or 8 groups of 12 comic books, thus taking the count to a <u>total of 10 ways</u> in which Sam can divide his comic books into equal groups.

Our question has been answered.

Simplify 5/8×8 and explanation thanks.
Paha777 [63]
Explanation: Since 5/8 x 8 can be answered (because there is no variable), turn the whole number "8" into a fraction which would be: 8/1. Now, 5/8 x 8/1 equals 40/8 because 5 x 8 = 40 and 8 x 1 = 8. Now, simplify 40/8, which would be 20/4, simplifying it, even more, would be: 10/2, and one more time: 5/1 which is equivalent to 5. Hope this helps!

Solve: 3^x+1 + 3^x= 108​
mash [69]

Answer:

x = 3

Step-by-step explanation:

{3}^{(x + 1)}  +  {3}^{x}  = 108 \\  \\  {3}^{x} .3 +  {3}^{x}  = 108 \\  \\  {3}^{x} (3 + 1) = 108 \\  \\  {3}^{x} (4 )= 108 \\  \\  {3}^{x}  =  \frac{108}{4}  \\  \\  {3}^{x}  = 27 \\  \\  {3}^{x}  =  {3}^{3}  \\  \\ \implies x = 3
