Answer:
362 kilometre
Step-by-step explanation:
Let a be the total cost of a journey
let b represent the total distance of a journey
$1.75 is a fixed charge of a journey
the additional charge is $0.10 for b distance ,hence total of additional charge is $.10 multiplied by b i.e 0.1 b
a=1.75+0.1b
a =37.90
37.90=1.75+0.1b
0.1b=37.90-1.75
0.1 b=36.15
b=36.15
/0.10
b=361.5
b=362 kilometre
For the journey that cost 21.80
21.80=1.75+0.1 b
0.1 b=21.80-1.75
0.1 b=20.05
b=20.05
/0.1
b=200.5
b =201 kilometre
-1/5x - 18 = 2
-x - 18(5) = 2(5)
-x = 10 + 90
-x = 100
x = -100
In order to redraw a scale drawing with a new scale, here are the steps that you need to follow : 1. Measure up the current scale and the size of the drawing 2.

Answer:
The relationship between x and y is 6.
Step-by-step explanation:
6 - 0 = 6
10 - 4 = 6
Answer:
x = 26
Step-by-step explanation:
because JKL is 90 degrees
x+8 + 2x+4 =90
3x + 12 =90
3x = 78
x = 26
