Answer:
$15.21
Step-by-step explanation:
The tax and tip percentages are both being figured on the original bill amount, so they can be added. The tax and tip together come to ...
11.75% +15% = 26.75%
This is added to the original bill amount, so the final total will be ...
$12 + $12×0.2675 = $12×1.2675 = $15.21
Vera's meal cost $15.21.
Hello,
We know that all the angles shown add up to 360 (think of a circle).
We also know that the angle of (6x-1)° is congruent to the angle opposite of it. (the "top left" angle) = 6x - 1°
We also know that the angle of (7x-1)° is congruent to the angle opposite of it.
(the "bottom left" angle) = 7x -1°
Knowing the sum of all angles as well as the angle measures in terms of x, we can add all the angle measures and equal it to 360.
So, we get (7x - 1) + (7x - 1) + (6x - 1) + (6x - 1) = 360
Simplify and we get:
26x - 4 = 360
Add 4 to both sides to get 26x = 364
Divide by 26 on both sides to get 14.
x = 14
Hope this helps!

Answer:
The relation between m and n is , m = n
Step-by-step explanation:
Given as :
The average for n class = 0.82 = 82%
The average for m class = 0.78 = 78%
The average for ( m + n ) class = 80%
So , 
= 82%
And 
= 78%
And , 
= 80%
So , 0.82×n + 0.78×m = 0.80× (m+n)
Or, 0.82×n - 0.80×n = 0.80×m - 0.78×m
Or, 0.02×n = 0.02×m
Or, 
= 
∴ = 1
I.e m = n
Hence The relation between m and n is , m = n Answer
