luisa has 12 playing cards.she place 2 out of every 3 cards face up how many cards are face up and how many are face down

Natasha2012 [34]

If 2/3 of the cards are face-up, then 2/3*12=8 cards are face-up. The remaining 12-8=4 cards are therefore face down.

A-2=-1 + 2a-4-1 send me the work please! (solving equations with variables on both sides)

Vladimir [108]

The value of "a" is 4

Solution:

Given expression is:

$a - 2 = -1 + 2a - 4-1$

The above expression involves variables and constants

A variable is a symbol that represents an unknown number

Here the variable is "a"

Constants are fixed numbers like 1, 2 etc

From given expression:

$a - 2 = -1 + 2a - 4-1$

Move the varibale "2a" from right side to left side of equation

When, 2a is moved from R.H.S to L.H.S, it becomes -2a

$a -2a - 2 = -1 -4-1$

Now move the constant -2 from left side to right side of equation

Similarly, when -2 is moved from L.H.S to R.H.S, it becomes +2

$a-2a = -1-4-1+2$

Now add the variables on left side of equation

$-a = -1-4-1+2$

Now add the constants on right side of equation

$-a = -6+2\\\\-a = -4$

Cancel the negative sign on both sides of equation

$a=4$

Thus the value of "a" is 4
