Option B
5 hundredths is not the way to express 0.50
<h3><u>Solution:</u></h3>
Given that Three of the choices are ways to express 0.50
To find: wrong option
Let us first write 0.50 in different ways
<h3><em><u>
To convert a Decimal to a Fraction follow these steps:
</u></em></h3>
Step 1: Write down the decimal divided by 1, like this: decimal 1.
Step 2: Multiply both top and bottom by 10 for every number after the decimal point. ...
Step 3: Simplify (or reduce) the fraction.

means 50 hundredths
<h3>Therefore option D is correct</h3>
On simplifying
we can write,

means one half
<h3>Therefore option A (one half) is correct</h3>
Similarly, \frac{5}{10} means 5 tenths
<h3>Therefore Option C is also correct</h3>
Thus the wrong option is B
<em><u>Justification:</u></em>
5 hundredths can be written as:

Therefore option B is wrong
Answer:
Step-by-step explanation:
The answer is B
The whole numbers are the + integer set. Since -sqrt(25) = - 5, this number is not included in the whole number set.
Answer:
9 1/6 yd
Step-by-step explanation:
First, list the lengths of ribbon Laura had or acquired:
8 3/10 yd + 4 3/5 yd. This is equivalent to 8 3/10 yd + 4 6/10 yd, or
12 9/10 yd.
Next, list the lengths of ribbon Laura used:
1 2/5 yd + 2 1/3 yd. The LCD here is 15, so we have 1 6/15 yd + 2 5/15 yd.
Summing up, we get 3 11/15 yd.
Subtract this length from the original 12 9/10 yard with which Laura began:
12 9/10 yd or 12 27/30 yd (LCD is 30)
- 3 11/15 yd or -3 22/30 yd
Subtracting the latter two quantities, we get 9 5/30 yd, or 9 1/6 yd
Let, the number = n
It would be: 2n = 28
n = 28/2
n = 14
In short, Your Answer would be 14
Hope this helps!

Answer:
Option 4
Step-by-step explanation:
Firstly, we need to make the two x's or the two y numbers the same. Lets multiply the second equation by 2:
(2x + 3y = 5 ) * 2 =
4x + 6y = 10
Now, subtract the second equation from the first one:
(4x - y = -11) - (4x + 6y = 10)
4x - 4x = 0
-y - 6y = -7y
-11 - 10 = -21
-7y = -21
Divide both sides by -7:
y = 3
Plug 3 into the first equation as y:
4x - 3 = -11
4x = -11 + 3
4x = -8
x = -2
So x = -2 and y = 3. We need to find one of the options that equals this.
<h3>Option 1)</h3>
-4x - 9y = -21
-10y = -30
40x - 90y = -210
-90y = -270
40x - 0 = 40x
-90y - - 90y = -90 + 90 = 0y
-210 - -270 = -210 + 270 = 60
40x = 60
x = 1.5
We already know this isn't equivalent because the x value is not the x value of the given equation.
<h3>Option 2) </h3>
4x + 3y = 5
2y = -6
_______
8x + 6y = 10
6y = -18
8x - 0 = 8x
6y - 6y = 0
10 - -18 = 10 + 18 = 28
8x = 28
x = 3.5
So we know this isn't equivalent because again, the x value isn't the same as the given equation.
<h3>Option 3</h3>
7x - 3y = -11
9x = -6
-----------
63x - 27y = -99
63x = -42
----------------
63x - 63x = 0
-27y - 0 = -27y
-99 - - 42 = -99 + 42 = -57
-27y = -57
-9y = -19
9y = 19
y = 19/9
So we know this one isn't equivalent as the y value isn't the same as the given equation.
<h3>Option 4</h3>
12x - 3y = -33
14x = -28
x = -28/14 = -2
12(-2) - 3y = -33
-24 - 3y = -33
-3y = -33 + 24
-3y = -9
y = 9/3
y = 3
So x = -2 and y = -3 which is the same as the first equation.
