Answer:
2/3
Step-by-step explanation:
We can find the slope by using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 12-18)/(20 -11)
= -6/-9
= 2/3
Answer:
Percentage score will be 83.33 %
Step-by-step explanation:
We have given Antonette gets 70 % on 10 problem test
Let consider here here total problem = total marks
So marks get 10 10 problem test = 10×0.7 = 7
Marks get in 20 problem test = 20×0.8 = 16
And marks get in 30 problem test = 30×0.9 = 27
Now total marks get get by Antonette = 7 +16 + 27 = 50
And total marks = 60
So percentage score of Antonette
%
we know that
1) You have
of a pie leftover after your party
2) Each
guest takes home
of the leftover pie
To find the fraction of the original pie does each guest take home,
Multiply
by 
so

<u>Simplify </u>
Divide by
both numerator and denominator

therefore
<u>the answer is</u>

Let
x-----------> <span>the first number
y-----------> </span><span>the second number
we know that
x*y=x-----------> y=x/x----------> y=1
and x+y=y------> x=y-y---------> x=0
the answer is
</span> the first number is 0
the second number is 1<span>
</span>
