one kilometer is equal to a hundred thousand centimeters
1..... 8(x+6)=-64
8x+48 =-64
8x =-64-48
8x=-112
X=-112/8
x=-14....
2.....3(4-2y)=-15
12-6y=-15
-6y=-15-12
-6y = - 27
y=27/6
y=4½....
3.....8w-3w+6=41
5w=41-6
5w=35
W=35/5
w=7....
4.....9x+3+x=-77
10x=-77-3
10x=-80
x=-8...
5.....10(-x-2)=120
-10x-20=120
-10x=120+20
-10x=140
x=140/-10
x=-14...
You shouldn't have a problem with the rest now....
Explanation:
The equation for this problem can be modeled in y = mx + b form.
m represents the rate of change and b represents the initial value or constant.
y = 10x + 20
x represents the number of hours he spent delivering newspapers
y is his total money after whatever number of hours he worked
The rate is 10, because it determines how much money he earns for each hour.
The y-intercept is 20, representing the starting amount of money in his bank account.
52? ahh thats what im thinking. Maybe wait for someone elses answer
