The experimental probability of tossing tails is 3/10
(2x+40)+(3x+20)=180
because they are supplementary angles
therefore:
2x+3x+40+20=180
5x+60=180
5x=120
x=24
Answer:
A.
Step-by-step explanation:
8x3(y+1)
is the answer of the question
C=p(t+30)
Let’s substitute in our values...
c=2(245+30)
Get the sum of what we have in parentheses...
c=2(275)
And finally
c=550
The answer is 4. .75x 4= 3
