Toppr Admin · Accepted Answer

Given that x - y - 3 - 5-0r-xy-35Let us assume that x - 3k and y - 5k3x-4y8x-5y-3-3k-4-5k-8-3k-5-5k-9k-20k24k-25k-29k49k-2949Hence 3x - 4y - 8x - 5y - 29 - 49

If $x : y = 3 : 5$ find ratio $3 x + 4 y : 8 x + 5 y$

Given that x : y = 3 : 5
(0r) $\frac{x}{y} = \frac{3}{5}$
Let us assume that x = 3k and y = 5k
$\frac{3 x + 4 y}{8 x + 5 y} = \frac{3 (3 k) + 4 (5 k)}{8 (3 k) + 5 (5 k)}$
$\frac{9 k + 20 k}{24 k + 25 k} = \frac{29 k}{49 k} = \frac{29}{49}$
Hence 3x + 4y : 8x + 5y = 29 : 49

If x:y=3:5 find ratio 3x+4y:8x+5y

Given that x : y = 3 : 5(0r)xy=35Let us assume that x = 3k and y = 5k3x+4y8x+5y=3(3k)+4(5k)8(3k)+5(5k)9k+20k24k+25k=29k49k=2949Hence 3x + 4y : 8x + 5y = 29 : 49

If $x : y = 3 : 5$ find ratio $3 x + 4 y : 8 x + 5 y$

Given that x : y = 3 : 5
(0r) $\frac{x}{y} = \frac{3}{5}$
Let us assume that x = 3k and y = 5k
$\frac{3 x + 4 y}{8 x + 5 y} = \frac{3 (3 k) + 4 (5 k)}{8 (3 k) + 5 (5 k)}$
$\frac{9 k + 20 k}{24 k + 25 k} = \frac{29 k}{49 k} = \frac{29}{49}$
Hence 3x + 4y : 8x + 5y = 29 : 49
