Answer:
The number of different choices is 720.
Step-by-step explanation:
The sales representative must visit six cities.
The visits of cities are independent.
Number of choices for the first visit: 6 possibilities
Number of choices for the second visit: 5 possibilities (He just visited one city, the sales representative don't have to go again)
Number of choices for the Third visit: 4 possibilities
Number of choices for the fourth visit: 3 possibilities
Number of choices for the Fifth visit: 2 possibilities
Number of choices for the Sixth visit: 1 possibilities
To count all the possibilities we have to multiple all of them:
6x5x4x3x2x1=720 different choices
Isolate the variable, note the equal sign, what you do to one side, you do to the other.
1) 4k = 24
Isolate the variable, k. Divide 4 from both sides of the equation:
(4k)/4 = (24)/4
k = 24/4
k = 6
2) 34 + h = 60
Isolate the variable, h. Subtract 34 from both sides of the equation:
34 (-34) + h = 60 (-34)
h = 60 - 34
h = 26
3) 1/5x = 30
Isolate the variable, x. Multiply 5 to both sides of the equation:
(5) * (1/5)x = (30) * (5)
x = 30 * 5
x = 150
4) m - 42 = 85
Isolate the variable, m. Add 42 to both sides of the equation:
m- 42 (+42) = 85 (+42)
m = 85 + 42
m = 127

Any repeated fraction is written as the number devided by nine(s).
for example
0.1111... =1/9
0.23232323... = 23/99
so the given number= -2 -7/9 = -25/9
If she needs 8 cups of flower for 4 eggs, when you could change that to needing 4 cups of flower for 2 eggs, now we know every 4 cups of flower is 2 eggs, and we already know 8 cups of flower is 4 eggs, so if we add 2 more eggs and that means 4 more cups of flower, the final answer is: 12 cups of flour is 6 eggs. To make it easier to remember, just remember if you have even numbers you can split them into pieces and just add those pieces over and over until you get it. We started with 8 cups of flour is four eggs, and if you put it to its smallest part It would be 4 cups of flower for 2 eggs, then you just have to remember how to count your 4’s and 2’s and it’s as easy as that
