Answer:
x = -10
Step-by-step explanation
5x+7(-3x-14)=162
First, 5x -21x - 98 = 162
Then, combine like-terms, -26x - 98 = 162
After that, add 98 to 162, and you'll end up with 260.
Finally, you'll wanna divide the -26x to the 162.
You'll end up with x = -10
Answer:
3x+4
Step-by-step explanation:
just combine like terms
x+2x= 3x
3+1=4

Determine the shortest possible distance
To better explain my solution, I've added an attachment that illustrates her movement.
Using the attachment as a point of reference, the shortest distance is calculated by calculating the length of the hypotenuse using Pythagoras theorem.
So, we have:
![x^2 = 6^2 + 8^2](https://tex.z-dn.net/?f=x%5E2%20%3D%206%5E2%20%2B%208%5E2)
![x^2 = 36 + 64](https://tex.z-dn.net/?f=x%5E2%20%3D%2036%20%2B%2064)
![x^2 =100](https://tex.z-dn.net/?f=x%5E2%20%3D100)
Take positive square root of both sides
![x = \sqrt{ 100](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%7B%20100)
![x = 10](https://tex.z-dn.net/?f=x%20%3D%2010)
Answer:
D
Step-by-step explanation:
Month*
divide 840 with 12
as 1 year has 12 months
and you get 70$
so the family spends $70 every month
