X - 6 = 0
X - 6 (+6)= 0 (+6)
X = 6

X + 2 = 0
X + 2 (-2)= 0(-2)
X = -2

Use the identity:
P(A or B)=P(A)+P(B)-P(A and B)
Substitute given values,
0.88=0.62+0.47-P(A and B)
=>
P(A and B)=0.62+0.47-0.88=0.21

Solve for x.
DerKrebs [107]

Answer:

Step-by-step explanation:

Remark

They are asking you to combine like terms. The total should be 180.

Givens

2 angles

  • 8x - 3
  • 4x + 3

Total 180

Solution

8x - 3 + 4x + 3 = 180        The threes cancel. So add what's left. They are of opposite signs, so they cancel.

12x = 180                           Divide both sides by 12

12x/12 = 180 /12                        

x = 15
