Answer:
0.5
Step-by-step explanation:
42 divided by 2/3 = 7
7 divided by 2/7 = 0.5
Answer:
x=16
Step-by-step explanation:
y = 1/2 x -3
Let y =5
5 = 1/2 x -3
Add 3 to each side
5+3 = 1/2 x -3+3
8 = 1/2x
Multiply each side by 2
8*2 = 1/2x*2
16 =x
<h3><u>
Answer:</u></h3>
Hence, the equation of line is:
y= -6x
<h3><u>
Step-by-step explanation:</u></h3>
Clearly from the graph we could see that the line passes through the point (0,0) and (-1/2,3).
Also we know that the equation of a line passing through (a,b) and (c,d) is given as:

Here we have:
(a,b)=(0,0) and (c,d)=(-1/2,3)
Hence, the equation of line is:

Hence, the equation of line is:
y= -6x
I'm assuming that % means $:
8.95*2 = 17.9
23.65 - 17.9 = 5.74
