2x -3y = 13
4x -y = -9
Multiply the second equation by -3 to make the coefficient of Y opposite the first equation.
4x -y = -9 x -3 = -12x + 3y = 27
Now add this to the first equation:
2x -12x = -10x
-3y +3y = 0
13 +27 = 40
Now you have :
-10x = 40
Divide each side by -10:
x = 40 / -10
x = -4
Now you have a value for x, replace that into the first equation and solve for y:
2(-4) - 3y = 13
-8 - 3y = 13
Add 8 to both sides:
-3y = 21
Divide both sides by -3:
y = 21/-3
y = -7
Now you have X = -4 and y = -7
(-4,-7)
2/7 x 1/3 = 2/ 21
In simplest form 2/21 = 2/21
Answer + 2/21
Answer:
the fraction of the USB drive when one video file use is 10%
Step-by-step explanation:
The computation of the fraction of the USB drive when one video file use is given below:
= USB drive × number of video file ÷ number of video file
= half × 1 ÷ 5
= 0.5 × 1 ÷ 5
= 0.10
= 10%
Hence, the fraction of the USB drive when one video file use is 10%
I got 16,000 tubes are sold in half a day because there are 720 minutes in 12 hours, and 43,200 seconds in 720 minutes then you divide by 2.7 and get 16,000
Step-by-step explanation:
In ten minutes she walked 1-0.5=0.5 miles.
60 minutes/10 minutes=6. So 0.5 miles ×6=3 miles per hour
