How to write twice the difference of z and 12 equal 63
Answers
Answer: 2(z - 12) = 63
Step-by-step explanation:
Our task is to write the following:
- twice the difference of z and 12 equals 63
So first, the difference of z and 12 means we're subtracting z and 12, and it's written this way:
Next, twice that difference is: . The reason why we need to put parentheses is because that way, 2 is multiplied by both z and -12.
This equals 63:
Answer:
2(z - 12) = 63
Step-by-step explanation:
Twice --> 2*
Difference of z and 12 --> (z-12)
Equals 63 --> = 63
If you combine...
2*(z-12) = 63
You can remove the * sign, because there is a bracket next.
2(z - 12) = 63

Step-by-step explanation:
At a grocery store 3 cans of soup cost $6.90
3 cans = 6.90
1 can= 6.90/3
1 can = $2.3
Therefore the cost of 10 cans can be calculated as follows
1 can= $2.3
10 cans= 10×2.3
= $23
Hence 10 cans will cost $23

Answer:
When we have a rectangle of width W and length L, the area of this rectangle can be calculated as:
A = W*L
In this case we have:
W = x
L = 10/x.
Then the area of the rectangle will be:
A = W*L = x*(10/x) = 10
So the value of x cancels in the equation, which means that we can not find the value of x.
Now, as L = 10/x we can find some restrictions:
if x = 0, we would have L = 10/0
So we can not have x = 0.
And as W = x, this represents a positive measure, we also have that x can not be a negative number.
So the relation:
W = x
L = 10/x
Gives us all the possible combinations of width and length such that the area of the rectangle is exactly 10 square units.
