<span> the product of 50 and 74 is 3,700</span>
Answer:
2x+3
Step-by-step explanation:
2(x+4)-5
2x+8-5 8-5=3
2x+3
Using the distance formula:
Distance = √((x2-x1)^2 + (y2-y1)^2)
Distance = √((5-2)^2 + (-8 - -4)^2
Distance = √(3^2 + -4^2)
Distance = √(9 +16)
Distance = √25
Distance = 5
Rate = 2 seats/11 minutes = 2/11 seats/min
Therefore the time required for s seats is
![(m \, min) = \frac{s \, seats}{ \frac{2}{11} \, \frac{seats}{min} } = \frac{11s}{2} \, min](https://tex.z-dn.net/?f=%28m%20%5C%2C%20min%29%20%3D%20%20%5Cfrac%7Bs%20%5C%2C%20seats%7D%7B%20%5Cfrac%7B2%7D%7B11%7D%20%5C%2C%20%20%5Cfrac%7Bseats%7D%7Bmin%7D%20%7D%20%3D%20%20%5Cfrac%7B11s%7D%7B2%7D%20%5C%2C%20min)
That is,
m = (11s)/2 min
When s = 16, obtain
![m = \frac{11(16)}{2} = 88 \, min](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B11%2816%29%7D%7B2%7D%20%3D%2088%20%5C%2C%20min)
When s = 19, obtain
![m = \frac{11(19)}{2} = 104.5 \, min](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B11%2819%29%7D%7B2%7D%20%3D%20104.5%20%5C%2C%20min)
Answers:
![m = \frac{11s}{2}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B11s%7D%7B2%7D%20)
When s = 16, m = 88 min
When s = 19, m = 104.5 min
Answer: x = 8
Step-by-step explanation:
- Distribute the 4 into (x - 3). The new equation should be 4x - 12 = 20.
- Add 12 on both sides. The new equation is 4x = 32.
- Divide 4 on both side. The solution is x = 8.
