Answer:
x = 44
Step-by-step explanation:
6 + 5 = 11
1/4x = 11
11 ÷ 1/4 = 44
if it does not make sense, then here is the equation.
1/4(44) - 5 = 6
Answer:
12 liters
Step-by-step explanation:
Let the solution with 30% acid solution be x litres
And the solution of with 70% alcohol to be y liters
X = Volume of 30% solution in liters
Y = Volume of 70% solution in liters
For acid solution,
30/100 × x = 0.3x
For alcohol solution,
70/100 × y = 0.7y
Since we need 54% of the combination of the 2 solutions: 54/100 = 0.54
The combination of the 2 solutions must give us 54 solutions combination and that is:
0.3x + 0.7y = 0.54(x+y)___ equation 2
X+y = 20_____ equation 1
solve the system of equations and we have:
From equation 2, x +y = 20
Therefore x = 20 -y
Replace the above in equation 2
0.3(20 - y) + 0.7y = 0.54(20)
6 - 0.3y + 0.7y = 10.8
Collect like terms
0.4y = 4.8
Y = 12 liters and that means 12 liters of 70% alcohol solution

Answer:
A = ≈4.17 ft²
Step-by-step explanation:
Even though the problem deals with shapes and area, we can use algebra to solve for the missing area of Square C. Gven the following formulas:
A (square) = s², where s = the measure of one side
A (rectangle) = l x w, where l = length and w = width
We can set up equations to solve for the side length of Square C to find the area. Since the area of Square A = 6 ft²:
A = 6 or 6 = s² so √6 = √s² or s = √6
So, the length of Rectangle B is √6 and the area = 5 ft², so we can solve for 'w', which is also the side length of Square C:
A = 5 ft² or 5 = l x w so 5 = √6w and w = 5/√6
Lastly, find the area of Square C:
A = s² or A = (5/√6)(5/√6) or area = ≈4.17 ft²
