Answer: Infinitely Many Solutions
Step-by-step explanation is below.
Take x-2=0
x=2
put the value of x in the equation
2^2 + 3(2) + k =0
4+6+k=0
10+k=0
k= -10
hope you understand
Hmmm......
Then, you must be thinking of 19.
Explanation:
Let you numher be x
now
according to question
multiply it by 8 and it becomes 8×x = 8x
Now add 22
so it becomes
8x + 22
now as told in the question take the same number again i.e x for one more time.
multiply it by 6
and you'll get 6x
and after adding 60 you'll get 6x + 60
Now again according to question
8x+ 22 and 6x+60 are same number therefore they must be equal,
8x+22 = 6x+60
Do a little azebra
8x -6x = 60 -22
2x = 38
x = 19.
and Tada, your number is here.
Answer: 3
Explanation:
She has 18 and uses half, 18/2=9
So now she has 9 eggs left, she uses one third, 9/3=3 (3 eggs is one third)
Now she only has six eggs left, she used half of those six to make dinner 6/2=3
She now has 3 eggs remaining.
