Answer:

x = 3 and y = 1

Step-by-step explanation:

The given equations are :

6x + 14y = 32  ...(1)

6x - 14y = 4 .....(2)

Add equation (1) and (2) :

6x + 14y + 6x - 14y = 32 + 4

12x = 36

x = 3

Put the value of x in equation (1)

6(3) + 14y = 32

18 + 14y = 32

14y = 32-18

14y = 14

y = 1

Hence, the value of x is 3 and y is 1.

alisha [4.7K]

Answer:

Fraction of jokes of Brandon that are funny = \frac{3}{10}

Step-by-step explanation:

We are given that, 30% of the Brandon's jokes are funny.

Now, to convert percent into fraction, we will multiply it by \frac{1}{100}

Now,

30\%=30\times\frac{1}{100}=\frac{30}{100} = \frac{3}{10}

∴ \frac{3}{10} of the Brandon's jokes were funny.
