Answer:
y=7
Step-by-step explanation:
Assuming that the equation is 14-2y=0
We need to isolate 'y' variable to obtain its value, to do that, lets start by subtracting -14 to both sides of equality sign,
14-2y=0 is now this: 14-14-2y=0-14, which is equals to -2y=-14
Now, lets continue by dividing by -2 both sides of equality sign.
We have this
-2y/-2=-14/-2
y=7
Thus, we've obtained the value for 'y' variable
in this situation it would be the last one or d.
Answer:
The total number of ways in which the 5 people can sit is: 5!=120: 5!=120
Let us assume that person d and e are sitting together and are taken as a single entity, the number of ways in which 4 people can sit is: 4!=24: 4!=24
The number of ways in which d and e are not sitting together: 1120−24=96.
Answer:
The answer is 138 degrees.
Step-by-step explanation:
Add both the opposite sides and, according to the Exterior Angle Theorem, the sum of those to sides will equal the exterior angle.
