Adele's error was she should have multiplied the total of all the choices.
Answer:
a=45 b=65
Step-by-step explanation:
You know that all the angle measures of a triangle add to 180. So the equation would be angle a + angle b + 70 = 180. Subsitute and simplify and you get 16x -2 + 70 = 180. Subtract 70 from 180 to get 16x -2=110 add 2 to get 16x =110. Divide each side by 16 to gte x=7. Subsitute x = 7 into the equations for angle a and angle b to get the answers above
We need to calculate a TIME. Here, TIME = job / rate
Here,
1 JOB 1 1
------------------------------------- = ------------------ = ---------------
JOB/5 min + JOB/15 min 1/5 + 1/15 3/15+1/15
1
= ------------ minutes = 15/4 minutes = 3 3/4 minutes (answer)
4/15
