Answer:
Angle M = 63
Angle N = 96
Step-by-step explanation:
By exterior angle of triangle:
Angle M + Angle N = 159
(4y+3)+(6y+6)=159
y = 15
Angle M = 4y + 3 = 4(15) + 3 = 63
Angle N = 6y + 6 = 6(15) + 6 = 96
Answer:
The percentage of the guests at this hotel called for room service yesterday is 40%
Step-by-step explanation:
We are given
total number of guests called for room services =170
total number of guests did not called for room services =255

Total number of guests =(total number of guests called for room services)+(total number of guests did not called for room services)
so,
total number of guests is
=170+255
=425
now, we can find percentage
percentage of the guests at this hotel called for room service yesterday is
%

The percentage of the guests at this hotel called for room service yesterday is 40%
Answer:
B (1/2,-2)
Step-by-step explanation:
4b + 13c = -24 --(1)
12b - 5c = 16 --(2)
(1)x3
12b + 39c = -72 --(3)
(3)-(2)
12b + 39c - 12b + 5c = -72-16
c = -2
Sub c = -2 into (1)
4b = -24 - 13(-2)
b = 1/2
