i think that that the answer is 13 Step-by-step explanation:
7 is the answer, you have to divide 475 by 78 and you get 6.08974358974359 but you round it up to 7 to make sure you have enough buses
The answer is negative 5 because you subtract 12 from each side to get 5x=-25 and -25 divided by 5 is negative 5
Answer:
x = 4
Step-by-step explanation:
It is given that , and we have to solve the given equation for x.
Now, we have
Squaring both sides we get
⇒ x - 3 = x + 6√x + 9 {Since we know the formula of (a + b)² = a² + 2ab + b²}
⇒ 6√x = - 12
⇒ √x = -2
Again squaring both sides we get
⇒x = 4 (Answer)
Answer:
