Simplify 5/8x -2y +3/4x-8y

AleksandrR [38]

Answer:

On simplification, $\frac{5}{8}x - 2y + \frac{3}{4}x -8y = (\frac{11}{8}) x - 10y$

Step-by-step explanation:

Here, the given expression is:

$\frac{5}{8}x - 2y + \frac{3}{4}x -8y$

Now, we can perform operations only on LIKE TERMS,

So, in this expression, separate the like terms we get:

$\frac{5}{8}x - 2y + \frac{3}{4}x -8y = \frac{5}{8}x + \frac{3}{4}x - 2y -8y\\= (\frac{5}{8} + \frac{3}{4})x -(2y + 8y) = (\frac{5 + 3(2)}{8}) x - (10y)\\= (\frac{11}{8}) x - 10y\\\implies \frac{5}{8}x - 2y + \frac{3}{4}x -8y = (\frac{11}{8}) x - 10y$

Hence, on simplification, $\frac{5}{8}x - 2y + \frac{3}{4}x -8y = (\frac{11}{8}) x - 10y$

Jacky baked some biscuits.he kept 3/7 of the biscuits in container A.5/8 of the remainder in container B and rest in container C

Colt1911 [192]

Let "b" represent the number of biscuits Jacky baked.
.. container A holds (3/7)b
.. container B holds (1 -3/7)*(5/8)b = (5/14)b
.. container C holds (1 -3/7 -5/14)b = (3/14)b = 168

Then
.. b = 168/(3/14) = 784

Jacky baked 784 biscuits.
