Answer:
-3,694
I am not sure what in the world the rest means, so I am very sorry. I just subtracted some stuff. I have no clue if that helped...
4/5+18/x=8
18/x=8-4/5
18/x=36/5
90=36x
x=5/2
The length would be 12 and the width 3
Theoretical probability (TP) is given by:
TP=[Number of favorable (desired) outcomes]/[Total number of possible outcomes]
From the information given:
Number of purple blocks=19
Total number of possible outcomes=125
thus;
TP=19/125
=0.152
Both students are correct; the slope should be -1, passing through through (4,2) with a y-intercept of 6.
