Answer:
D
Step-by-step explanation:
every number is either even or odd so half of infinite possibilities.
Answer:
This system of equations has <em>no solution</em>. It is inconsistent.
Step-by-step explanation:
The last equation tells you z = -1.
Substituting this value for z in the other two equations allows them to be written as ...
-3x -y = 7
-3x -y = 3
There are no values of x and y that can make both these equations true.
Answer:
first blank 8, 2nd blank 12
Step-by-step explanation:
plug X into the equation to find y
y = -4(-2) = 8
y = -4(3) = -12
There are 12 five minutes in one hour and 1 hour correspond to 360°, then each 5 minutes represents 360/12 = 30°
From 1:20 to 1: 55 we have 35 minutes or 7 x 5 minutes or
7 x 30° = 210°
To convert degree into radian, we apply the following formula:
degree/180° = radian/π
210/180 = r/π or (cross multiplication) →Radian = (π x 210/180
→ Radian = 7π/6 (simplify by 30)
