Step-by-step explanation:
There can be a lot of math expressions that may equal 13. Here are some of the expressions that equal 13.
Now, let us consider some interesting expression
If the value of x = 2, then the expression will be equal to 13.
i.e.
∵ when x = 2
Considering a word problem
<em>'Tom has 10 oranges while Tony has 3 more oranges than Tom. How many oranges Tony has?</em>
Let 'x' be the number of oranges Tom has.
The number of oranges Tony has = x + 3
as Tom has 10 oranges, so x = 10
Therefore, the number of oranges Tony has = x + 3
= 10 + 3 = 13
Therefore, the number of oranges Tony has = 13
Given:
The given expression is
To find:
The simplified form of given expression.
Solution:
We have,
The common factors in numerator and denominator are e, e, f.
Cancel out the common factors.
Therefore, the required expression is 
.
Answer:
x=2,y=2
Step-by-step explanation:
3y-1 = 5
or, 3y = 5+1
or, y = 6/3
y = 2
2x+1 = 3y-1
or, 2x = 3×2-1-1
or, 2x = 4
or, x = 2

Answer:
P(t)= 9000(0.4)^t
Step-by-step explanation:
Generally, we have an exponential function as follows;
P(t)= I(1 - r)^t
This case represents a decay ( decrease in value)
from what we have;
I represents the initial value, whereas r is the rate of change
From the question, we have that the change rate is the fraction 3/5
Writing this as a decimal, it is 0.6
substituting this back into the equation, we have;
P(t)= I(1-0.6)^t
P(t)= I(0.4)^t
I in this case is 9,000
So we have it that;
P(t) = 9000(0.4)^t
