Answer:

Ali = 12, Sami  = 21

Step-by-step explanation:

Ali = 4x, Sami = 7x

lets make an equation

3x=15

x=3

Now when we know x we can find how many candies each got

3*4=12, 3*7=21

What is the simplified form of the expression k^3(k7/5)^-5
saveliy_v [14]
The expression can be simplified as:

k^3(k7/5)^-5
= k^(3+-5) * (7/5)^-5
(Collecting the powers of k at one side and the constants at other side)
= k^-2 * (5/7)^5
(Solving thr integer powers)
= k^-2 * (3125/16807)

Anon25 [30]

We are given the following values:

0.125 pound

0.1 pound

0.12 pound

 

All values start with the same number which is 0.1, therefore the 0.1 is the smallest.

Next the two values are followed by 0.12, so 0.12 is the next smaller number.

So the largest number is 0.125.

 

Arranging from least to greatest amount of trail mix eaten:
