Answer:
$175
Step-by-step explanation:
If after a 20% discount, it cost $140, the $140 is only 80% of the cost.
So divide 140 by 4 then multiply the answer by 5 to get it back to 100%
140/4=35
35x5=175
The general equation of the circle is:
(x -xo)^2 + (y - yo)^2 = r^2
Where xo,yo are the coordinates of the center and r is the radius of the circle.
Here (xo,yo) is (-16,30) and you can find the radius.
You can find the radius using the equation of the distance (Pythagoras) between the center (-16,30) and any point on the circunference. Here use (0,0)
r^2 = (-16 - 0)^2 + (30 - 0)^2 = 1156
Then, the equation is>
(x - (-16) )^2 + (y - 30)^2 = 1156
=> (x + 16)^2 + (y - 30)^2 = 1156. <----- answer
Answer:
the number is 20
Step-by-step explanation:
6% of x = 20% of 6
0.06x=0.20*6
0.06x=1.20
x=1.20/0.06
x=20
Answer:
x = -7
Step-by-step explanation:
-2x - 10 = 4
-2x = 14 | Add 10 to both sides
x = -7 | Divide both sides by -2
