Step-by-step explanation:
u should:
7t = t + 48 » 7t - t = 48 » 6t = 48 » t = 8
and another one is:
2u + t + 13 = 10t + u - 44» 2u + 8 + 13 = 80 + u - 44»
» 2u + 21 = u + 36 » 2u - u = 36 - 21 » u = 15
The slope-intercept form:

m - slope
b - y-intercept
The formula of a slope:

We have two points (2, 0) and (-2, -4). Substitute:

Therefore we have the equation of a line

Put the coordinates of the point (2, 0) to the equation:
<em>subtract 2 from both sides</em>

Answer: 
10x + 2y - 6 = 0
Multiply 5x + y - 3 = 0 by 2
2(5x + y - 3 = 0) = 10x + 2y - 6 = 0
Simplified expression that represents the cost of renting 6 scooters is 18 j +30
<u>Step-by-step explanation:</u>
Given data:
The cost of renting of a scooter is represented by 3j +5
So, from that, we can say in general,
The cost of renting of n scooters is represented by

But according to given, the value of n is 6. i.e. to find the cost for six number of scooters. We can calculate now as follows
So, the cost of renting of a scooter is represented by
