8 - 4 = 7 - 3 because it has a equal sign in the middle meaning that you have to find an equation that’s equal to it. So thats why the missing number is 3

are you serious? If you are, here’s the explanation:
It’s like finding x
8-4=7-x
Let’s simplify it, we know that 8-4=4
4=7-x
Now, we wanna get x by itself, since that’s what we’re looking for.
Go ahead & get rid of 7. Since 7 is a positive number, well subtract it. Also, remember that what we do on one side, we must do to the other side, so subtract 7 on BOTH sides
4-7=-x
Simplify.
-3=-x
Now, we need x to be positive, so let’s get rid of the negative sign (-).
We’ll do this by dividing -1 on BOTH sides.
3=x ——> x=3
Hope this helps! :)

The original value of a car is $24,000. It depreciates 15% annually. What is its value in 4 years? $
ValentinkaMS [17]

Answer:

Future Value = $ 12528.15

Step-by-step explanation:

The depreciation is applied to the car annually. The value of the car after depreciation in "n" no. of years can be given by the following formula:

Future\ Value = (Present\ Value)(1-depreciation\ rate)^n\\

where,

Future Value = ?

Present Value = $ 24000

Depreciation Rate = 15% = 0.15

n = no. of years = 4

Therefore,

Future\ Value = (\$ 24000)(1-0.15)^4

<u>Future Value = $ 12528.15</u>

[(M^2N^2-MN)(M^2N^2+MN)]/MN
GaryK [48]

Answer:

Step-by-step explanation:

M²N² - MN = MN (MN - 1)

M²N² + MN = MN (MN + 1)

\frac{(M^{2}N^{2}-MN)(M^{2}N^{2}-MN)}{MN}= \frac{MN(MN-1) * MN(MN + 1)}{MN}\\

                                     = (MN - 1) * MN * (MN + 1)

                                     = (MN - 1)(MN +1) MN             {(a+ b)(a - b) = a² - b² }

                                     = (M²N² - 1²) * MN

                                    = (M²N² - 1)MN

Erin planted t tomato plants. Leo planted 5 fewer tomato plants than Erin. Filipe planted 10 fewer tomato plants than Erin. Drag
Setler [38]

<u><em>Answer:</em></u>

Total number of plants = 3t - 15 = 3(t-5) tomato plants

<u><em>Explanation:</em></u>

<u>We are given that:</u>

Erin planted t tomato plants

Leo planted 5 fewer tomato plants than Erin, <u>this means that:</u>

Leo planted = t - 5 tomato plants

Fillip planted 10 fewer tomato plants than Erin, <u>this means that:</u>

Fillip planted = t - 10 tomato plants

Now, we want to find the total number of tomato plants

<u>This means that</u> we will add the number of plants planted by Erin, Leo and Fillip

<u>Therefore:</u>

Total number of plants = t + t - 5 + t - 10

Total number of plants = 3t - 15 = 3(t-5) tomato plants

Hope this helps :)
