Answer:
Option c
or 
Step-by-step explanation:
The absolute value is a function that transforms any value x into a positive number.
Therefore, for the function
x> 0 for all real numbers.
Then the inequation:
has two cases
if
(i)
if
(ii)
We solve the case (i)

We solve the case (ii)

Then the solution is:
or 
Answer:
the two angles are 55° each
Step-by-step explanation:
Let the two equal angles be y each
Therefore,
70° + y + y = 180°
Collect like terms
2y = 180 — 70
2y = 110
Divide both side by the coefficient of y i.e 2
y = 110/2
y = 55°
Therefore, the two angles are 55° each
12.857 days
Step-by-step explanation:
Since the number of days is passing the same for both Nick and Perry we can assign the unknown value (no. Of days) the same denotation of x
Therefore;
180 – 6x = 0 + 8x
180 = 8x + 6x
180 = 14x
X = 12.857
