Answer:
x=4
Step-by-step explanation:
20x+5+24x-1=180
44x+4=180
- 4 -4
44x=176
/44 /44
9514 1404 393
x = 4
The two marked angles are supplementary when the lines are parallel.
(20x +5)° +(24x -1)° = 180°
44x +4 = 180 . . . . . . simplify
44x = 176 . . . . . . . . . subtract 4
x = 4 . . . . . . . divide by 44
__
The two angles are ...
(20·4 +5)° = 85°
(24·4 -1)° = 95°
B) 16
8s-4=7s+12
s-4=12
s=16
y=35+x+15x/100. since x is the money earn so 15percent of x
Quadratic
Linear has a constant growth and exponential cannot be negative.
