First you change the number that is not with "p" and it changes with the opposite sign
-0.75p = 0.25 + 2
-0.75p = 2.25
then as -0.75 and p are multiplying, you pass -0.75 as dividing
p = 2.25/-0.75
p = 3
Answer:
100 42/100
Step-by-step explanation: you put the change as a fraction
So if it is 3x^2+4x=2 then
set one side to zero
subtract 2 from both sides
3x^2+4x-2=0
this is not factorable by normal means so use quadratic formula which is if you have the equation in ax^2+bx+c=0 form you can solve for x if you put it into this equation quadratic formula
![x=\frac{-b+ \sqrt{b^2-4ac} }{2a} or \frac{-b- \sqrt{b^2-4ac} }{2a}](https://tex.z-dn.net/?f=%20x%3D%5Cfrac%7B-b%2B%20%5Csqrt%7Bb%5E2-4ac%7D%20%7D%7B2a%7D%20or%20%20%5Cfrac%7B-b-%20%5Csqrt%7Bb%5E2-4ac%7D%20%7D%7B2a%7D)
so if you were to input it into this equation you would get
a=3
b=4
c=-2
the solution is
![x= \frac{-2+ \sqrt{10} }{3} or \frac{-2- \sqrt{10} }{3}](https://tex.z-dn.net/?f=x%3D%20%5Cfrac%7B-2%2B%20%5Csqrt%7B10%7D%20%7D%7B3%7D%20or%20%5Cfrac%7B-2-%20%5Csqrt%7B10%7D%20%7D%7B3%7D%20)
the answer is C
I think its 1000 numbers because there from 1 to 999 there are 999 numbers, and then you add zero because it is also a whole number.
The video game is on 35% discount.
Step-by-step explanation:
Cost of video game = $50
Price on sale = $32.50
Amount of discount = Original price - price on sale
![Amount\ on\ discount = 50-32.50\\Amount\ on\ discount= \$17.5](https://tex.z-dn.net/?f=Amount%5C%20on%5C%20discount%20%3D%2050-32.50%5C%5CAmount%5C%20on%5C%20discount%3D%20%5C%2417.5)
Percentage = ![\frac{Dicount\ Price}{Original\ Price}*100](https://tex.z-dn.net/?f=%5Cfrac%7BDicount%5C%20Price%7D%7BOriginal%5C%20Price%7D%2A100)
![Percentage=\frac{17.5}{50}*100\\Percentage=\frac{1750}{50}\\Percenatge=35\%](https://tex.z-dn.net/?f=Percentage%3D%5Cfrac%7B17.5%7D%7B50%7D%2A100%5C%5CPercentage%3D%5Cfrac%7B1750%7D%7B50%7D%5C%5CPercenatge%3D35%5C%25)
