D. 24
Step-by-step explanation:
A prime number is a number that only has 2 factors, which is 1 and itself. In other words, a prime number is only divisible by 1 and itself.
19 is a prime number, because it is only divisible by 1 and itself.
11 is also a prime number because it is only divisible by 1 and itself.
5 is also a prime number because it is only divisible by 1 and itself.
24 is not a prime number because it is divisible by 1 and itself, but it is also divisible by 2, 3, 4, 6, 8, and 12.
The answer is D.
Answer:
3x+7+ x= -11-2x
4x + 2x = -11-7
6x = -18
x = -18/6
x = -3
therefore , the number is -3
now,
by putting value,
3x+7+x=-11-2x
3*(-3)+7+(-3)=-11-2*(-3)
-9+7-3=-11+6
-5=-5
