To sum two fractions, you have to transform them in order to have the same denominator: if you multiply both numerator and denominator of the first fraction by 8, and numerator and denominator of the second by 3, you have

\dfrac{2}{3} = \dfrac{2\cdot8}{3\cdot8} = \dfrac{16}{24}

\dfrac{3}{8} = \dfrac{3\cdot3}{8\cdot3} = \dfrac{9}{24}

Now we can easily sum the fractions, because we only have to sum the numerators:

\dfrac{2}{3} + \dfrac{3}{8} = \dfrac{16}{24} + \dfrac{9}{24} = \dfrac{16+9}{24} = \dfrac{25}{24}

a system of equations has infinitely many solutions. if 2y – 4x = 6 is one of the equations, which could be the other equation?
deff fn [24]
<span>A system of equations has infinitely many solutions when the two lines representing the equations coincide. i.e. the two equations are the same or a multiple of each other.
2y - 4x = 6
2y = 4x + 6
2y = 2(2x + 3)
y = 2x + 3
-y = -(2x + 3)
-y = -2x - 3
Hence the other equation is -y = -2x - 3</span>

Please help me! I will make you as the best answer
Alexandra [31]

Answer:

40

Step-by-step explanation:

The area of a rectangle is length*width. So, 200=8(1/2x+5). Dividing by 8, 25=1/2x+5. Subtracting 5, 20=1/2x, multiplying by 2, 40=x.
