Answer:
C. 24 meters
Step-by-step explanation:
Given:
Total length of fabric required for the costume = 56.6 m
Length of fabric Zhou already has = 15 m
Length of fabric James just purchased = 17.6 m
To find how much more length of fabric is required to make the complete costume.
Solution:
<em>Let the length of fabric in meters still required be</em> = 
<em>The total length can be given as :</em>
⇒ 
⇒ 
The total fabric required = 56.6 m
So, the equation to find
will be:

Subtracting both sides by 32.6

∴ 
Thus,<u> 24 meters</u> of fabric is still required to make the costume.
Answer: y = 3/2x - 2
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
For a point to be on the unit circle, the sum of the squares of the point's coordinates must be 1. Each value that is a fraction will have a square that is smaller than it is.
A: the given values add to 1; the sum of their squares cannot be 1.
B: a correct choice
C: one of the given values is more than 1, so the point cannot be on the unit circle
D: a correct choice
Given:
The equation is

To find:
The reason for second step.
Solution:
We have,

Using multiplication property of equality, multiply both sides by 3.

Using addition property of equality, add 4 on both sides.


Using division property of equality, divide both sides by 2.


So, the reason for second step is multiplication property (=).
Therefore, the correct option is D.
