For this case by similarity of triangles we can use the following relationship:
(x) / (9) = (5) / (15)
We clear the value of x:
x = ((5) / (15)) * (9)
Rewriting:
x = (1/3) * (9)
x = 3
Answer:
The value of x for this case is:
x = 3
Answer:
-50/6 or -25/3
Step-by-step explanation:
to isolate x, you multiply -5/2 to each side.
10/3 * -5/2
when you simplify you get
-25/3
Answer:
8000001
Step-by-step explanation:
D (x, y) ---> (x, -y)
We can look at Point X and Point X'.
Point X is at (2, -2), and Point X' is at (2, 2).
The y-value has been multiplied by -1, or turned positive, so the answer would be D.
Answer:
109% of increase
Step-by-step explanation:
In order to know the increase in the percentage, we can do this in various methods, however let's follow the method using only rule of 3; you can also do it by the variation index, however, rule of 3 is easier.
First, we need to know the difference between 756$ and 1580$:
1580 - 756 = 824$
Now let's set the rule of three, assuming that 756 is 100% innitial:
756$-------->100%
824$--------> X
Solving for X:
X = 824 * 100 / 756 = 109.9947%
And if you round this number: 109%
