You can only solve this by having the same base on each side. So to change 1/27, you can use 3^-3, which is then multiplied through. So the equation is:

4x-5=-3(2x+10)
4x-5=-6x-30
10x=-25
x=-2.5

The n-th term of a number pattern is as follows:

Ilia_Sergeevich [38]

9 = 3² is not prime, so $T_9 = 9^2-8 = 81-8 = 73$ .

7 is prime, so $T_7 = 7\times7+6 = 55$ .

Then the difference is $T_9 - T_7 = 73 - 55 = \boxed{18}$ .

Answer:

78°

Step-by-step explanation:

Angles on a straight line = 180°

AD is the straight line

Angle BFA = 48

Angle CFD = 54

54 + 48 = 102

180 - 102 = 78

Therefore, Angle BFC = 78°
