Answer:
X = 51
Y = 12
Step-by-step explanation:
2 numbers: (Larger) Number 1 is x and Number 2 is y
The equation is x + y = 63
New equation is:
Combine like variables:
Solve:
- 4y + 15 - 15 = 63 - 15
- 4y = 48
Divide 4 from each side:
To find x fill in the variables from the 'x =' equation:
- x = 3y + 15
- x = 3( 12) + 15
- <em><u>x = 51</u></em>
Answer:
C. 11:16 AM
Step-by-step explanation:

Hope this helps :)
Answer:
-3
Step-by-step explanation:
Bring -2 to the other side and A to the other side
<em>-</em><em>2</em><em> </em><em>Become </em><em>2</em><em> </em><em>because </em><em>of </em><em>flipping</em>
<em>And </em><em>A </em><em>becomes </em><em>-A </em><em>because </em><em>of </em><em>flipping</em>
<em>2</em><em>-</em><em>2</em><em>+</em><em>3</em><em>=</em><em>-A</em>
<em>Flip </em><em>the </em><em>whole </em><em>equation </em><em>to </em><em>avoid </em><em>confusion</em>
<em>-A=</em><em>2</em><em>-</em><em>2</em><em>+</em><em>3</em>
<em>-</em><em>A=</em><em>+</em><em>3</em>
Bring the minus sign to the other side,
<u>A=-3</u>
<u>-</u><u>3</u><u> </u><u>-</u><u>2</u><u> </u><u>+</u><u>3</u><u> </u><u>=</u><u> </u><u>-</u><u> </u><u>2</u>
<u>Which </u><u>make </u><u>the </u><u>statement</u><u> </u><u>correct.</u>

Answer:
Step-by-step explanation:
Let the side length for the octagon having 9m² as area = x
Side length for the octagon having area of 25m² = y.
Thus:
(area of similar polygons theorem)
The scale factor of their sides would be 
. Which is:
Scale factor of their sides =
