Answer:
see attached
Step-by-step explanation:
The steps to solving an equation are those that undo the operations done to the variable. Here, the variable is multiplied by 2/3 and 15 is added to the product.
We undo the addition of 15 by subtracting 15 (from both sides of the equation).
We undo the multiplication by 2/3 by multiplying both sides of the equation by its inverse, 3/2.
It is useful to do simplification after each of these steps.
Attention needs to be paid to the signs. When 15 is subtracted from 9, a negative result is obtained. When that is multiplied by a positive number (3/2), a negative result remains.
Answer:
m<6 = 130°
Step-by-step explanation:
If m∠2 = 130°, what is m∠6?
Find the diagram attached
From the digram we can see that the vertical lines are parallel. Hence based on geometry;
m<2 = m<6 (corresponding angles)
Given m<2 = 130°, hence m<6 = 130°
Yes ,Because I whole is bigger or grater than
The best prediction of the total number of tagged salmon in a sample of 2000 is 100.
<h3><u>Predictions</u></h3>
To determine what is the best prediction of the total number of tagged salmon in a sample of 2000, the following calculation must be performed:
- 800 = 40
- 2000 = X
- 2000 x 40 / 800 = X
- 80000 / 800 = X
- 100 = X
Therefore, the best prediction of the total number of tagged salmon in a sample of 2000 is 100.
