One solution was found :
x = ∛15 = 2.466
Step by step solution :
Step 1 :
12÷x2
Equation at the end of step 1 :
3 12
(((((3x-————)+6x)-27)-2x)-——)-(6x-27) = 0
(x2) x2
Step 2 :
3÷ x2
Equation at the end of step 2 :
3 12
(((((3x-——)+6x)-27)-2x)-——)-(6x-27) = 0
x2 x2
You want to use the distributive property, i.e. the possibility to distribute a multiplication to both terms of an sum/subtraction.
In this case, if you think of 395 as of 400-5, you have

And you can use the distributive property to write

Both of these multiplications are easy to perform in your mind:

40 miles an hour and yeah..
Answer:
75
Step-by-step explanation:
First divide 2/5 to get 0.4. Then divide 30 by 0.4 to get the answer. A simple way to think about it is how many 0.4 grams are in 30 gram tube.
