9:20 am
Lcm is 80 so 80 minutes after 8 am is 9:20
Answer:
x=-16
Step-by-step explanation:
We are given with the equation
![40=-\frac{1}{3} \times (9x+30)+2](https://tex.z-dn.net/?f=40%3D-%5Cfrac%7B1%7D%7B3%7D%20%5Ctimes%20%289x%2B30%29%2B2%20)
We are asked to solve it for x.
Distributing
over bracket and simplifying
![40=-(\frac{9x}{3}+\frac{30}{3})+2](https://tex.z-dn.net/?f=40%3D-%28%5Cfrac%7B9x%7D%7B3%7D%2B%5Cfrac%7B30%7D%7B3%7D%29%2B2)
![40=-(3x+10)+2](https://tex.z-dn.net/?f=40%3D-%283x%2B10%29%2B2)
![40=-3x-10+2](https://tex.z-dn.net/?f=40%3D-3x-10%2B2)
![40=-3x-8](https://tex.z-dn.net/?f=40%3D-3x-8)
Adding 8 on both sides
![48=-3x](https://tex.z-dn.net/?f=48%3D-3x)
Dividing both sides by -3
![x=-16](https://tex.z-dn.net/?f=x%3D-16)
Answer:
0
Step-by-step explanation:
To find the slope of two points, here is the formula (y2-y1)/(x2-x1)
So we have (1,2) and (4,2),
We let y2 = 2 and y1 = 2 and we let x2 = 4 and x1 = 1
So, (2-2)/(4-1) = 0/3
Our slope is 0.
The answer is 8.
half of 16 is 8
