Just put the x number for x and solve equation

Why are the equations w - x x = w and w x - x = w called identities?
saveliy_v [14]
They are called identities because:
w-x = 0 
w = x (carry x to the other side) is the same as x = w

in the other case:
wx-x = w / divide by w on both side
x -x = 0
x = x (carry x to the other side)

In both cases the equations are the same.

Dominick is training for a race. He spends 0.75 hours running each time he runs and 1.5 hours swimming each time
umka2103 [35]

Answer:

The possible graph is "A". A further explanation is given below.

Step-by-step explanation:

The given values are:

Dominick spends on running

= 0.70 hours

He spends on swimming

= 1.5 hours

This week,

Dominick spends more than six hours.

If,

Number of runs be "x".

Number of swimming be "y".

then,

⇒ 0.75x+1.5y>6

⇒ 75x+150y>600

⇒ x+2y>8

Therefore, x+2y=8

x = 0

y = 4

So the above is the correct answer.
