Answer:

A = 58

B = 112

Step-by-step explanation:

A + B = 180                           Supplementary angles

B = 2A - 24                           Given

Substitute for B in the first equation

A + 2A - 24  = 180

3A - 24 = 180                         Add 24 to both sides

3A = 180 + 24                        Combine the right

3A = 204                               Divide both sides by 3

A = 204/3

A = 68

B = 2A - 24

B = 2*68 - 24

B = 136 - 24

B = 112

8x+6-9x= 2-x+4
8x+6+-9x=2+-x+4
(8x + -9x) + (6) = (-x) + (2+4) (combine like terms)
-x+6= -x+6
-x+6+x=-x+6+x

Answer:

f(2) = 7/4

Step-by-step explanation:

f(x) =  \frac{2x + 7 -  {x}^{2} }{4}  \\ f(2) =  \frac{2(2) + 7 -  {2}^{2} }{4}  \\ f(2) =  \frac{4 +  7- 4}{4}  \\ f(2) =  \frac{7}{4}
