Answer:
so 2x+3x+130=180
so 5x+130=180
5x=50
so 2x =20
3x which is angle a is equal to 30 degree
Add all those numbers and divide by 6 will get you 78
Answer:
0.04
Step-by-step explanation:
Given that a dart is to be thrown at a target. The probability the dart will hit the target (yes or no) on a single attempt is 0.20
Each throw is independent of the other throws.
Let x be the no of times the target is hit in the trial of 4 throws
Since each outcome is independent of the other X is binomial with n =4 and p = 0.20
Required probability
= the probability that it will take less than or equal to 4 throws to hit the target on both successful target hits
=P(X=2 when n =2) + P(x=2 when x =3) + P(x=2 when x =4)
= 
Answer:
There are no solutions
Step-by-step explanation:
−2(3x+4)−x+6=−5x−2(x+1)+5
(−2)(3x)+(−2)(4)+−x+6=−5x+(−2)(x)+(−2)(1)+5(Distribute)
−6x+−8+−x+6=−5x+−2x+−2+5
(−6x+−x)+(−8+6)=(−5x+−2x)+(−2+5)(Combine Like Terms)
−7x+−2=−7x+3
−7x−2=−7x+3
Step 2: Add 7x to both sides.
−7x−2+7x=−7x+3+7x
−2=3
Step 3: Add 2 to both sides.
−2+2=3+2
0=5
Answer - There are no solutions
