Answer:
D.
Step-by-step explanation:
The subtraction property involves subtracting the same number that is subtracted from one side of the equal sign and also subtracting same from the other side of the equal sign
For example: y + 3 = 2
To apply the subtraction property, subtract 3 from each side. Thus:
y + 3 = 2 - 3
From the given equation solved, the subtraction property was not applied in any of the steps shown.
Answer:
-y(7+y) =0
Step-by-step explanation:
-7y - y^2 = 0
Factor out a -y
-y(7+y) =0
Using the zero product property
-y =0 and 7+y =0
y=0 7-7+y = 0-7
y=0 y = -7
The numbers are best written as,
(1.2 x 10⁻²)(3.65 x 10⁸)
If we multiply the bases of the scientific notations, we get an answer of 4.38. There exists a rule which states that for exponents of the same number which are multiplied, we add up the exponents. Thus, our final answer would be,
4.38 x 10⁶
Answer:
Step-by-step explanation:
figure it out kid
Well, we would first have to write an equation. Let's start with letter (a). We will put in the variable (x) for the number of children there were, because we don't know how many there were. So... IF we knew how many children there were, what would we do to find out how much pie each child got? Of course, we would divide! Soooo....
6 (mangos) divided by x (the number of children) = 5/6
Now, we solve for x!
So, our first step in the equation 6/x=5/6 would be to multiply, because multiplication is the opposite of division! So, just let me see if I can work this.....
6/x(×)5/6
So, we now can cross multiply and get...
5x=36 (Because 5 time x is 5x and 6 times 6 is 36)
Now, we divide!
So, 5x/5 cancels out and we get just plain little x. 36/5 gives us.....
Improper Fraction Form: 36
Mixed Number Form: 7 1/5
Decimal Form: 7.2
And that's your answer! I really hope this helps! ^_^
