Answer:415
Step-by-step explanation:
Angle DBE + Angle CBE = 90°
(0.1x-22)° + (0.3x-54)° = 90°
(0.4x - 76)° = 90°
(0.4x)° = 166°
x= 1660/4 = 415
(0.1 415 - 22)° + (0.3 415-54)° = 90°
41.5 - 22 + 124.5 - 54 = 90
166 - 76 = 90
Answer:
F(x)= -19
Step-by-step explanation:
Just plug in ‘-3’ for every ‘x’ in the equation.
4(-3)-7
-12-7
F(x)= -19
Divide by 3 21/3=7
multiply by 2 7x2=14
<u>2/3 of 21 is 14</u>
