Answer:
80 degrees
Step-by-step explanation:
100 + angle A = 180
180-100= 80
So, the measure of angle A is 80 degrees
Y = 3x - 7 . . . . . (1)
6x - 2y = 12 . . . (2)
Putting (1) into (2) gives
6x - 2(3x - 7) = 12
6x - 6x + 14 = 12
14 = 12
Therefore, there is no solution.

Answer:
$54
Step-by-step explanation:
$44.97 round to $45
20% of $45 is $9
$45 + $9 = $54
Answer:
let this happens after t hours
so
80t + 60t = 392
140 t = 392
t = 392/140
=2.8 hours
