Answer:
Step-by-step explanation:
I assume you mean "if the ratio of 7 less than a number and 7 more than the number is 2".
Let x be the number.
Ratio is division.
(x-7)/(x+7)=2
Multiply by (x+7) on each side:
x-7=2(x+7) = 2x+14
Add 7 on each side
x=2x+21
Subtract 2
-x=21
x=-21

Step-by-step explanation:
In the graph of y = x2, the point (0, 0) is called the vertex. The vertex is the minimum point in a parabola that opens upward. In a parabola that opens downward, the vertex is the maximum point. We can graph a parabola with a different vertex.

Answer:
sorry i dont know
Step-by-step explanation:
X = original amount
x - 1/2x - 2 = 2/5x
1/2x - 2 = 2/5x
-2 = 2/5x - 1/2x
-2 = 4/10x - 5/10x
-2 = - 1/10x
-2 / (-1/10) = x
-2 * - 10/1 = x
20 = x <=== she was originally shipped 20 suits
