Step-by-step explanation:
vertical angles or line pairs
c=60
180-120=60
180-131=49
60+49=109
180-109=71
Answer:
Check once on regression to the mean
Check once on the availability hubristic
Check twice on sink cost effect
Check twice on the present aim standard of rationality.
Step-by-step explanation:
Since herb is driven by emotion and happenstance and not by actual overall statistics this seems like the way to answer the question.
All you have to do is start by multiplying 485 and 34 (485*34) to find how much he made by just weddings. That should be equal to 16,490. Then you have to multiply 18 by 87 because he charged 18 per copy and there was 87 copies so (18*87). This should now be equal to 1,566. Since you want the total you now should add them which should be 16,490+1,566 and that is equal to 18,056.
Answer:
You will need to use simultaneous equations.
Method:
First we need to make one set of variable the same, in this case we will:
-Multiply the top equation by 3 to get 6x
-Multiply the bottom equation by 2 to get 6x
The result will be as follows:
1) 2x+5y=-13 x3
1) 6x+15y=-39
2) 3x-4y=-8 x2
2) 6x-8y=-16
Now we will make both equations equal to 6x:
1) 6x=-15y-39
2) 6x=8y-16
Now because they both equal 6x, they therefore equal each other:
-15y-39=8y-16
-23=23y
y=-1
Now that we have y, we can substitute it back into one of the equations to get x:
1) 2x+5(-1)=-13
2x-5=-13
2x=-8
x=-4
