Let x=large boxes and y=small boxes.
x+y=110
60x+35y=5100
____________
You need to cancel out one of the variables to solve for one. Let's cancel out y.
-35(x+y=110)
-35x-35y=-3850
60x+35y=5100
____________
Add the two equations.
25x=1250
x=50
_____________
Plug in 50 for x into one of the equations to solve for y.
50+y=110
y=60
_____________
50 large boxes
60 small boxes
The y-intercept will be 1
Answer:
72.5
Step-by-step explanation:
Answer:
25% of 30% of 400 = 30
33% decrease in value
Step-by-step explanation:
You can either get 30% of 400 first then 25% of 400 or you can get the total percentage of 400.
Method 1:
30% of 400 = 0.3 of 400 = 0.3 * 400 = 120
25% of 120 = .25 of 120 = .25 * 120 = 30
Method 2:
30% of 25% = 0.3 * 0.25 = 0.075 = 7.5% of 400
7.5% of 400 = 0.075 of 400 = 0.075 * 400 = 30
5.) To find the percentage of the new price, you can build the equation below.
![\frac{new price}{original price} = \frac{percent}{100}](https://tex.z-dn.net/?f=%5Cfrac%7Bnew%20price%7D%7Boriginal%20price%7D%20%3D%20%5Cfrac%7Bpercent%7D%7B100%7D)
![\frac{200,000}{300,000} = \frac{x}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B200%2C000%7D%7B300%2C000%7D%20%20%3D%20%5Cfrac%7Bx%7D%7B100%7D)
![20,000,000 = 300,000x](https://tex.z-dn.net/?f=20%2C000%2C000%20%3D%20300%2C000x)
![x = 66.667](https://tex.z-dn.net/?f=x%20%3D%2066.667)
The percentage decrease in price is then 100% of the original price - 66.667% of the original price = 100% - 66.67% = 33.33% = 33% decrease.
repeating fraction, nice
2.16161616...=2+0.16161616...
solve the repeating part
let's say x=0.16161616
2 places repeat, multiply x by 10^2 or 100
100x=16.161616
now subtract x from taht
100x-x=16.161616-0.16161616
the repeats cancel and we get
99x=16
divide both sides b 99
x=16/99
so
16/99=0.16161616...
2+16/99 is the fraction
if ya wanted 1 fraction then
2+16/99=
198/99+16/99=
214/99
2.161616=214/99
