Step-by-step explanation:
Bringing like terms on one side
2 + 7 - 5 = 2x - 4x
9 - 5 = - 2x
4 = - 2x
4/ - 2 = x
- 2 = x
Answer:
3-
Step-by-step explanation:
C = 45 + 3.75m....the domain in this equation is gonna be ur m values...the number of magazines ordered....so the domain will be all whole numbers...and whole numbers are all positive numbers including 0...no fractions or decimals
If these permutations were in a line, then the equation would be n!. But since we are dealing with a circle, it's a little bit different, given that there is no specific beginning or end. This means that <span>you could rotate the circle around n different ways and still have the same circular permutation. Thus, this would be the expression you are looking for:
n!/n, which can be simplified as (n-1)!
The correct answer is the second option.</span>
348 miles——>15 gallons of gas
232 miles——-> x
X=(232)(15)/348=10 gallons of gas
