Answer:
30pages
Step-by-step explanation:
20 is 2/3 so 10 is 1/3 so 3/3 is one book
First, you must distribute the negative sign(otherwise considered a negative one). This gives you x - 4x + 7 = 5x - x - 21.
Then, simplify any like terms you can: -3x + 7 = 4x - 21.
Simplify this even further: 28 = 7x
The final answer is x = 4
Answer:
$343
Step-by-step explanation:
To get 30% of 490 we divide 30% by 1
30% ÷ 1 = 147
Now, we subtract 490 by 147
490 - 147 = 343
Answer:
4 > x
Step-by-step explanation:
5 (x + 3) - 4> 3x + 9 + 4x – 6
5x + 15 - 4 > 3x + 4x + 9 - 6
5x + 11 > 7x + 3
11 - 3 > 7x - 5x
8 > 2x
8/2 > x
4 > x
Hope this helps :D
100% = 320
20% = Blue tiles
35% = White Tiles
100% - 55% = Red Tiles = 45%
45% of 320
320 x 0.45 = 144 Red tiles
