21/49
= (21/7) / (49/7)
= 3/7.
The final answer is 3/7~
First you would need to combine like terms. do you know how to do that?
Answer:
If Ahmad travel 280 miles the cost of both plans will be the same
Step-by-step explanation:
Let's call x the number of miles traveled by Ahmad.
If we say that C1 is the cost of the first plan and C2 is the cost of the second plan then:
C1 = initial fee + additional cost per mile
C2 = initial fee + additional cost per mile
We want to know for what value of x, cost 1 will be equal to cost 2. Then we equate the equations and solve for x.

Answer:
x = (c -mp)/g
Step-by-step explanation:
Subtract the term not containing x, then divide by the coefficient of x.
gx +mp = c . . . . . given
gx = c - mp . . . . . subtract mp
x = (c -mp)/g . . . . divide by g

<em>Comment on the process</em>
This process can be described various ways. A usual description is "get the x term by itself on one side of the equal sign, then divide by the x-coefficient."
I like a more general description of the solution to "solve for" problems: undo what is done to the variable, in reverse order.
Here, the variable x is multiplied by g, then added to mp. To undo those operations (in reverse order), first we undo the addition of mp. We accomplish that by subtracting mp, or by adding the opposite of mp, as you wish.
Having done that, we undo the multiplication by g by dividing by g.
(gx)/g = (c -mp)/g
x = (c -mp)/g
The steps we actually perform here are identical to the steps in "get the x-term by itself, ...". However, the process we have described can be applied to any sort of equation, not just a 2-step linear equation.
