Do 51×5 and you will get the answer 255
Answer:
(5/7)m + 2n + 3
Step-by-step explanation:
Rewrite 3/7m as (3/7)m for added clarity, also 2/7m as (2/7)m.
Adding (3/7)m and (2/7)m results in (5/7)m.
Next, combine -3 and 6, which yields 3.
I expected that there'd be only one term in m in both quantities. (3/7)m - 3 + 4n does have only one term, but (2/7)m - 2m + 6) seems to have two m terms. I will assume that you actually meant (2/7)m - 2n + 6).
Combining like terms, we get (5/7)m + 3 + 4n - 2n, or
(5/7)m + 2n + 3
We have to simplify the given expression:

Dividing the terms of the numerator by the given term of denominator individually, we get
= 
By using the laws of exponent,
, we get
= 
= 
= 
= 
Therefore, the simplification of the given expression is
.
So, Option 3 is the correct answer.
After 2 miles, the cost will be same for both companies.
Step-by-step explanation:
Charges of Cabs'R Us = $4.00
Per miles charges = $3.00
Let,
x be the number of miles.
R(x) = 3x+4.00
Charges of Call A Cab = $2.00
Per mile charges = $4.00
A(x) = 4x+2.00
For same amount;
R(x) = A(x)

After 2 miles, the cost will be same for both companies.
