Step-by-step explanation:
thanks for your help
Let us assume the number of times Bill saved $75 from his paycheck = x
Let us assume he number of times Bill saved $150 from his paycheck = y
Since he saved 75$ or 150$ for the 8 paychecks.
So, x+y=8
y=8-x (Equation 1)
Since Bill saved $825 from his last 8 paychecks using $75 or $150.
So, 75x+150y=825 (Equation 2)
Substituting the value of 'y' from equation 1 in equation 2,
![75x+150(8-x)=825](https://tex.z-dn.net/?f=%2075x%2B150%288-x%29%3D825%20)
![75x+1200-150x=825](https://tex.z-dn.net/?f=%2075x%2B1200-150x%3D825%20)
![75x-150x=825-1200](https://tex.z-dn.net/?f=%2075x-150x%3D825-1200%20)
![-75x=-375](https://tex.z-dn.net/?f=%20-75x%3D-375%20)
x = 5
Therefore, Bill saved $75, 5 times from his paycheck.
Answer: x=-2
Y= -20
Step-by-step explanation
You replace the y in the second equation with 10x. This is because it says 10x=y
2x+10x=12x so you put that
12x=-24
To get x by its self you divide by 12.
-24 divided by 12 is -2.
Now you plug in -2 to either equation as y. I chose the first one because it's easier.
10(-2)=y
-20=y

Answer:
The speed of light in a vacuum is 186,282 miles per second
Step-by-step explanation:
The speed of light in a vacuum, commonly denoted c, is a universal physical constant that is important in many areas of physics.Its exact value is defined as 299 792 458 metres per second (approximately 300 000 km/s or 186 000 mi/s). It is exact because, by international agreement, a meter is defined as the length of the path traveled by light …
kilometers per hour: 1080000000
meters per second: 299792458
miles per hour: 671000000
