Answer:
there are varous answer to this problem but the equation is 30+n
just plug in any number for n and add 30.
Ex:
n=30
30+30=60
Ex:
n = 40
30+40=70
Hoped that helped:P
To solve this, we’ll have to use inverse operations.
Since addition is the inverse to subtraction, we’ll add 20 to 620.
20 + 620 = 640
From there, since division is the inverse of multiplication, we’ll divide .75 by 640.
640/.75 = 853.33333 repeating. We can round this to 853.33, to round to the nearest hundredth.
Therefore, 853.33 would be your answer! You can check this by solving the equation forwards (853.33 x .75 = ~640, 640 - 20 = 620.)
Hope this helps! :)
The solution of x in -6 + 3x - 9x^2 = -16 is 
<h3>How to solve the equation?</h3>
The equation is given as:
-6 + 3x - 9x^2 = -16
Add 16 to both sides
10 + 3x - 9x^2 = 0
Rewrite as:
9x^2 - 3x - 10 = 0
Solve for x using the quadratic formula
So, we have:
Evaluate
Hence, the solution of x in -6 + 3x - 9x^2 = -16 is
