Answer:
The Correct Answer is 
Complete the multiplication and the equation becomes
+
= ?
The two fractions now have like denominators so you can add the numerators.
=
Therefore, The Answer Is

Answer:
Step-by-step explanation:
(x + 7)° = (15 + 7)° = 22°
(4x + 8)° = (4*15 + 8)° = (60 + 8)° = 68°
To find the answer you need to write equivalent fractions with larger denominators. If you multiply each fraction by 3/3 then your equivalent fractions would be
3/5 × 3/3 = 9/15
4/5 × 3/3 = 12/15
Now we have two fractions that are equivalent to the original fractions and we can easily see that 2 fractions between 9/15 and 12/15 would be...
10/15 and 11/15
(10/15 can reduce to 2/3 so your answers could also be 2/3 and 11/15)
From (1), we get x = (8 - 3y) / 2 ––(3)
Substitute (3) into (2),
2 [(8 - 3y) / 2]² + 3y² = 110
(8 - 3y)² + 3y² = 220
15y² - 48y - 156 = 0
Therefore y = 5.2, then x = (8 - 3×5.2) / 2 = -3.8
OR y = -2, then x = [8 - 3×(-2)] / 2 = 7
The cordinates of A and B are (-3.8, 5.2) and (7, -2).
<h3><u>SOLUTION:</u></h3>
Let the length of the room = L = 12m
width of the room = b = 8m
Height of the room = h = 4m
• Area of the four walls of the room = Perimeter of the base x Height of the room.
- Cost of white washing per m² = ₹5
Hence , the total cost of white washing four walls of the room ;-
- Area of ceiling is 12 x 8 = 96m².
Cost of white washing the ceiling.
So , the total cost of white washing ;
- ₹ ( 800 + 480 ) = ₹ 1280 .
