Answer:

Below.

Step-by-step explanation:

The problem would look like this:

12 3/8 / 5 1/2

My math teacher told us to write it like a normal division problem.

12 3/8 ÷ 5 1/2

One way to solve is to turn both fractions into improper fractions, so..

12 3/8

So multiply 8 x 12 = 96 + 3 = 99/8

Then, 5 1/2, 2 x 5 = 10 + 1 = 11/2

99/8 ÷ 11/2, 99 ÷ 11 = 9, 8 ÷ 2 = 4,

So your answer would be 9/4, which is an improper fraction. To simply, just divide 9 by 4, and you would get 2 1/4 (mixed number).

Answer:9/4

Step-by-step explanation:

99/8*2/11=9/4*1/1=9/4

You can cancel out 99 and 11 to 9 and 1 as they are multiples of eac hother and you can do the same for 8 and 2 to 4 and 1

I found the dot plots that accompanies this problem.

Based on the plots, the <span>statement that gives is a valid comparison of the number of candies in the bags of the two Brands is:

</span><span>B. The number of candies in the bags from Brand B is greater and less consistent than the number of candies in the bags from Brand A.

Dots in Brand B are scattered and whereas dots in Brand A are not and they are more concentrated between 52 to 55 range. </span>

4^4x-5= 8^3x-4 solve

$4^{4x-5}=8^{3x-4}\\\\(2^2)^{4x-5}=(2^3)^{3x-4}\qquad\text{use}\ (a^n)^m=a^{nm}\\\\2^{2(4x-5)}=2^{3(3x-4)}\iff2(4x-5)=3(3x-4)\qquad\text{use distributive property}\\\\(2)(4x)+(2)(-5)=(3)(3x)+(3)(-4)\\\\8x-10=9x-12\qquad\text{add 10 to both sides}\\\\8x=9x-2\qquad\text{subtract 9x from both sides}\\\\-x=-2\to \boxed{x=2}$
