Answer:
F = P(1 - x)^n
F = 10,000(1 - 0.1)^7
F = 10,000(0.9)^7
F = $4,783
The value of the tractor in 7 years is $4,783
Step-by-step explanation:
Applying the exponential depreciation equation;
F = P(1 - x)^n
Where;
F = final value after n years
P = initial value
x = depreciation rate (fraction)
n = time
Given;
P = $10,000
x = 10% = 0.10
n = 7 years
Substituting the given values;
F = 10,000(1 - 0.1)^7
F = 10,000(0.9)^7
F = 4782.969
F = $4,783
The value of the tractor in 7 years is $4,783
<h2>Steps</h2>
So for this system, one equation will represent the number of fruit and the other equation will represent the combined total of the fruit. (Let x = apples and y = bananas):
Next, I will be using the substitution method to remove one of the variables. To do this, firstly subtract both sides by y in the first equation:
Next, since we know that x is equal to 20 - y, substitute it into the second equation and solve for y:
Now that we have the value of y, substitute it into either equation to solve for x:

<u>In short, Angelo bough 14 apples and 6 bananas.</u>
Answer:
So the answer is 12 and 31.
Step-by-step explanation:
Let the smaller number be x and the larger number be y.
We can calculate this by using simultaneous equation, aka listing 2 equations out.
From given,
X + y = 43
Let this be equation no. 1
X + 19 = y
Let this number be equation 2.
We can do simultaneous equations either by substitute method or elimination. In this case I'm using substitute.
We can already obtain the value of y (in terms of x) in euqation no. 2, so all we gonna do is to put y into equation 1.
X + x + 19 = 43
Solve this by algebra.
2x = 43 - 19
X = 12
Now we know the exact value of x
Now substitute x = 12 into equation no. 2
12 + 19 = y
Y = 31
