Answer:
Step-by-step explanation:
Given the algebraic expression;
To make n the subject of formula.
Cross-multiplying, we have;
Rearranging the equation, we have;
It is very important to read and understand the words of the problem before getting down to solving the given question. Numerous information's of immense importance are already given in the question. Those information's will come in handy while solving the question.
Let us assume the unknown number to be = x
Then
3x - 2 = 13
3x = 13 + 2
3x = 15
Dividing both sides of the equation by 3, we get
(3/3) * x = 15/3
1 * x = 5
x = 5
So the unknown number is 5. I hope the procedure is not very tough for you to understand.
Answer:
The associative property is a math rule that says that the way in which factors are grouped in a multiplication problem does not change the product.

Step-by-step explanation:
A ratio is a relation between two numbers.
*A ratio determines how many times 20 contains/values 8.
<u>A ratio representing the width to the length is: </u>
8:20.
8 represents the width, 20 represents the length.
To simplify a ratio, you must divide each side by the same number.
<u>S</u><u>i</u><u>mplified </u><u>ratios</u><u> </u><u>are</u><u>:</u>
4:10 (Divide by 2)
2:5 (Divide by 4)
1:2.5 (Divide by 8)
The ratio is detailing that the length is 2.5 times larger than the width.
<u>Your answers are;</u>
8:20
4:10
2:5
1:2.5
For this case we have the following function:
y = 1 \ 2 (5) ^ x
We apply the following function transformations:
Reflections:
To graph y = -f (x), reflect the graph of y = f (x) on the x-axis. (Vertical reflection)
y = -1 \ 2 (5) ^ x
Horizontal translations
Suppose that h> 0
To graph y = f (x-h), move the graph of h units to the right.
y = -1 / 2 (5) ^ (x-3)
Answer:
Reflection on the x axis.
Horizontal movement 3 units to the right
