Answer:
= 4n - 13
Step-by-step explanation:
There is a common difference d between consecutive terms , that is
d = - 5 - (- 9) = - 1 - (- 5) = 3 - 1 = 7 - 3 = 4
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 9 and d = 4, thus
= - 9 + 4(n - 1) = - 9 + 4n - 4 = 4n - 13
Answer:
10x+5
Step-by-step explanation:
You would add 3x and 7x
you would leave 5 alone because it has no x thus it can not be added to the 3x and 7x

Step-by-step explanation:
really thought this was the answer huh look at you
Answer:
A = 40x + 175
B = 50x + 125
5 hours
Step-by-step explanation:
The equations are as follows:
According to the question
Let us assume the number of hours be x
For company A
40x + 175
For company B
50x + 125
Now equate these two equations
40x + 175 = 50x + 125
175 - 125 = 10x
x = 5
Hence, the number of hours is 5
