If they give you the total price and the price after the discount you can use this "formula" to solve it p/100=b/a where p is the percentage, a is the total price and b is the price after the discount.
Step-by-step explanation:
1. -9x - 3 - 3 + 2x
-7x - 6
3. 3 - 4x - 7x - 2
-11x - 1
4. 5x - 1 + 3 + 2x
7x + 2
Step-by-step explanation:
you move -5y to the other side.
25=-5y-3xsubtract 25 both sides
0=-5y-3x-25then add 5y both sides
5y=-3x-25divide 5 both sides
y=-3/5x-5
m=-3/5 do rise over runrise/run
b=(0,-5)plot it
3 down and 5 to right or 3 up and 5 left
A = length x width
15,000 = (w + 30) x w
15,000 =
+ 30w
0 =
+ 30w - 15,000
Use quadratic formula to find that w= -15 + or - 5
. Because distance cannot be negative, the width is -15 + 5
meters or approximately 108.39 meters. This means that the length is approximately 138.39 meters.
Answer:
'''who else has trouble with math and then gets ridiculed and made fun of by teachers and adults and other, smarter students and then just wants to die?''
YES!
