Answer:
C: x=-10
Step-by-step explanation:
Alternate interior angles are congruent to each other meaning that x+80=70 making x equal to -10. I hope this helped and this is one of my favorite units so post more these questions :)
Answer:
Step-by-step explanation:
-3x + 3y = 6.......(1)
y= 4x + 5............(2)
Putting (2) in (1)
-3x + 3(4x + 5) = 6
-3x + 12x + 15 = 6
9x = 6 -15
9x = -9
x = -9/9
x = -1
Putting x in (2)
y= 4x + 5
y = 4(-1) + 5
y = -4 + 5
y = 1
Answer:
![Rate = 0.2167\ fl\ oz/hour](https://tex.z-dn.net/?f=Rate%20%3D%200.2167%5C%20fl%5C%20oz%2Fhour)
Step-by-step explanation:
Given
![Rate = \frac{91\ fl\ oz}{2.5\ weeks}](https://tex.z-dn.net/?f=Rate%20%3D%20%5Cfrac%7B91%5C%20fl%5C%20oz%7D%7B2.5%5C%20weeks%7D)
Required
Express the rate as per hour
![Rate = \frac{91\ fl\ oz}{2.5\ weeks}](https://tex.z-dn.net/?f=Rate%20%3D%20%5Cfrac%7B91%5C%20fl%5C%20oz%7D%7B2.5%5C%20weeks%7D)
There are 168 hours in a week;
So, the rate becomes
![Rate = \frac{91\ fl\ oz}{2.5 * 168\ hours}](https://tex.z-dn.net/?f=Rate%20%3D%20%5Cfrac%7B91%5C%20fl%5C%20oz%7D%7B2.5%20%2A%20168%5C%20hours%7D)
![Rate = \frac{91\ fl\ oz}{420\ hours}](https://tex.z-dn.net/?f=Rate%20%3D%20%5Cfrac%7B91%5C%20fl%5C%20oz%7D%7B420%5C%20hours%7D)
![Rate = 0.2167\ fl\ oz/hour](https://tex.z-dn.net/?f=Rate%20%3D%200.2167%5C%20fl%5C%20oz%2Fhour)
Hence;
The equivalent of the given rate is ![0.2167\ fl\ oz/hour](https://tex.z-dn.net/?f=0.2167%5C%20fl%5C%20oz%2Fhour)
