Answer:
<u>x=6</u><u> y=16</u>
Step-by-step explanation:
I will use elimination
y=2x+4
y=2x+x-2
*3 y=2x+4 3y=6x+12
*2 y=3x-2 2y=6x-4
3y=6x+12
- 2y=6x. -4
<u>y=16</u>
16=2x+ 4
-4 -4
12= 2x
/2 /2
<u>6=x</u>
Answer:0.367
Step-by-step explanation:
Given
There are 6 cans of regular and 7 cans of diet cola
number of ways of selecting 2 regular colas and 1 can of diet cola is
![\Rightarrow ^6C_2\times ^7C_1](https://tex.z-dn.net/?f=%5CRightarrow%20%5E6C_2%5Ctimes%20%5E7C_1)
The total no of ways of selecting 3 items out of 13 items is
![\Rightarrow ^{13}C_3](https://tex.z-dn.net/?f=%5CRightarrow%20%5E%7B13%7DC_3)
Probability is
![\Rightarrow P=\dfrac{^6C_2\times ^7C_1}{^{13}C_3}=\dfrac{105}{286}\\\Rightarrow P=0.367](https://tex.z-dn.net/?f=%5CRightarrow%20P%3D%5Cdfrac%7B%5E6C_2%5Ctimes%20%5E7C_1%7D%7B%5E%7B13%7DC_3%7D%3D%5Cdfrac%7B105%7D%7B286%7D%5C%5C%5CRightarrow%20P%3D0.367)

Answer:
Conway is 312.50 miles from Littleton
Step-by-step explanation:
Given
![Scale: 1\ in = 50\ mi](https://tex.z-dn.net/?f=Scale%3A%201%5C%20in%20%3D%2050%5C%20mi)
See attachment
Required
Distance between Conway and Littleton
The scale distance between Conway and Littleton is 6.25 inches.
So, the actual distance is calculated as:
![1\ in = 50\ mi](https://tex.z-dn.net/?f=1%5C%20in%20%3D%2050%5C%20mi)
Multiply both sides by 6.25
![6.25 * 1\ in = 50\ mi * 6.25](https://tex.z-dn.net/?f=6.25%20%2A%201%5C%20in%20%3D%2050%5C%20mi%20%2A%206.25)
![6.25\ in = 312.50\ mi](https://tex.z-dn.net/?f=6.25%5C%20in%20%3D%20312.50%5C%20mi)
<em>Hence, Conway is 312.50 miles from Littleton</em>
