8 X
----- = ------
20 40000
40000/20=2000
2000*8=16000
X=16000
Answer:
23
Step-by-step explanation:
You need to draw a line of best fit, then extend the x-axis, but from inspection I think it is 23.
(19 is too low, 36 is too high)
If you would like to solve the equation -5x - 25 = 78, you should do this using the following steps:
<span>-5x - 25 = 78
</span>-5x - 25 + 25 = 78 + 25
-5x + 0 = 103
-5x = 103 /(-5)
x = 103 / (-5)
x = - 103/5 = - 20.6
The error was already made at step 1.
