The number that was squared would be 4
Answer:
40%
Step-by-step explanation:
6/15 * 100 = 0.4 * 100 = 40%
Answer:
Find the value of x(attachment 11)
6)
7x = 6 + 5x
7x - 5x = 6
2x = 6
x = 6/2 = 3
7)
30 = 4x + 6
4x = 30 - 6 = 24
x = 24/4 = 6
8)
2(x + 4) =16
x + 4 = 16/2 = 8
x = 8 - 4 = 4
9)
7 + 5x = 3x + 13
5x - 3x = 13 - 7
2x = 6
x = 6
<u>Find the area(From attachment 2)</u>
1) Area = 4* 5 = 20
2)Area = 7 * m = 7m
3). Area = 3* a = 3a
4). Area = x*x = x²
5). Area = 4*x + 3* 4 = 4x + 12
6). Area = 7*a + 7*9 = 7a + 63
7). Area = 3x*x + 2*3x = 3x² + 6x
<u>expression of line segment</u>
8) x + 9
9). x + 4
10). a + 2
Answer:
The answer is 4 liters.
Step-by-step explanation:
We want a final 25% solution, which means that the solvent should constitute 25 percent of all the liters of solution.
Let us call 
the litres of 40% solution, so when they are added to the 12 litres of 20% solution, the total litres of the new solution are:
of these liters, 25% must be the solvent:
Now for the 40% solution, the liters of the solvent are 
, and for the 20% liter solution, the liters of solve are 
liters. Thus the total liters 
of the solvent are
Therefore
