Answer:
Step-by-step explanation:
y+2x-3+4x^2+3x-5y
Combine terms
4x^2-4y+5x-3
Since a triangles angles add up to 180 you would add the other sides and then
180-161=19
So angle 1 is 19 degrees
Answer:
it goes 1.25 km per minute
Step-by-step explanation:
7.5 divided by 6=1.25
5x-4-x=4(x+1)
5x-4-x=4(x)+4(1)
(5x-x)-4=4x+4
4x-4=4x+4
+4 +4
4x=4x+8
/4 /4
x = x+2
-x -x
0=2
Answer: p = 1/25
Step-by-step explanation:
Ok, you know that the probability of rolling a six is p = 1/5
now, if you want to have two sixes, then you have two events with a probability of 1/5.
And as you know the joint probability for two events is equal to the product of the probabilities, then the probability of rolling two sixes is:
p = (1/5)*(1/5) = 1/25.
