Answer:
The numbers are -16,-15 and -14
Step-by-step explanation:
Let
x ----> the first number
x+1 ----> the second number
x+2 ---> the third number
we know that
(1/4)x+(1/5)(x+1)=(1/7)(x+2)-5
Multiply by (4*5*7) both sides
35x+28(x+1)=20(x+2)-140*5
35x+28x+28=20x+40-700
43x=-688
x=-16
so
x+1=16+1=-15
x+2=-16+2=-14
Answer: 80 degrees because a line is 180°.
So if you subtract
180 - 100 = 80°

The coefficient is the number being multiplied with the variable, since p is simply just p, it's just being multiplied by 1.

the pattern is plus 6
