0.25Q+0.1(2Q)+0.05(2Q+14)=4

0.25 Q + 0.1 (2 Q) + 0.05 (2 Q + 14) = 4

Q = 6

Solution steps

0.25 Q + 0.1 (2 Q) + 0.05 (2 Q + 14) = 4

Remove parentheses:

(a) = a

0.25 Q + 0.1 \cdot 2 Q + 0.05 (2 Q + 14) = 4

Multiply the numbers:

0.1 \cdot 2 = 0.2

0.25 Q + 0.2 Q + 0.05 (2 Q + 14) = 4

Add similar elements:

0.25 Q + 0.2 Q = 0.45 Q

0.45 Q + 0.05 (2 Q + 14) = 4

Multiply both sides by

100

45 Q + 5 (2 Q + 14) = 400

Expand

5 (2 Q + 14) : 10 Q + 70

45 Q + 10 Q + 70 = 400

Add similar elements:

45 Q + 10 Q = 55 Q

55 Q + 70 = 400

Move

70

to the right side

55 Q = 330

Divide both sides by

55

Q = 6

\frac{x y}{x + y}

x \frac{3}{4} = 27

7 - 6

x^{2} + x^{2} = 1 2^{2}

- 3 = x^{2} + 4 x
