Verify -(-x) =x for x =(-2/3)​

Given,

x=

15

2

Then,

−(−x)

=−(−

15

2

)=

15

2

As we know that by the sign rule of multiplication: (-ve) multiplied (-ve) equals (+ve)

Hence, proved −(−x)=x.

is should be y = 5x

step-by-step explanation:

correct me if im wrong

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
