Answer:
The set {x | x is an even prime number, x<150} has 1 element.
Step-by-step explanation:
Prime Numbers: The numbers which have no factors other than 1 and the number itself are called prime numbers.
Even Numbers are those numbers which are completely divisible by 2.
So, the only EVEN PRIME NUMBER = 2
Now, Set = {x | x is an even prime number, x<150}
So, the set has {2} as its only element.
Hence, the total elements in the set is 1.
Or, the set {x | x is an even prime number, x<150} has 1 element.
Kx^2-x-1=0
Kx^2-x=1
Kx^2=1+x
K=1+x/x^2
Answer:

in settings probable
Step-by-step explanation:
Answer:
(a). 11
(b). 16
Step-by-step explanation:
(a). 6=22
3=x solve for x doing 22(3)/6
(b). 6=22
24=x solve for x doing 22(24)/6
<span>Angle 7 and 5 are vertical angles, so they're equal.
Angles 7 and 8 are supplementary, so they have to add up to 180.
2x + 15 + 3x = 180
Solve for x, then plug it into the expression for angle 7 to get you answer</span>
