Answer:

An odd number times an even number is always even

e.g 2 × 3 = 6

4 × 5 = 20

adding 1 to an even number makes it odd

6 + 1 = 7

20 + 1 = 21

hope this helps...

Quick! Andrew has to play 15 games in a chess tournament. At some point during the tournament he has won half of the games he ha

nikklg [1K]

$x$ - the number of the games he played

$\dfrac{x}{2}$ - the number of the games he won

$\dfrac{x}{3}$ - the number of the games he lost

$x=\dfrac{x}{2}+\dfrac{x}{3}+2\Big|\cdot6\\6x=3x+2x+12\\x=12$

$15-12=3$

<u>so, he has still 3 games to play</u>

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{x = 11}}}}}$

Step-by-step explanation:

$\sf{ - 2(3 - 2x) = - 6x + 8(x + 2)}$

Distribute -2 through the parentheses

Similarly, Distribute 8 through the parentheses

$\dashrightarrow{ \sf{ - 6 + 4x = - 6x + 8x + 16}}$

Collect like terms

$\dashrightarrow{ \sf{ - 6 + 4x = 2x + 16}}$

Move 2x to left hand side and change it's sign

Similarly, move 6 to right hand side and change it's sign

$\dashrightarrow{ \sf{4x - 2x = 16 + 6}}$

Collect like terms

$\dashrightarrow{ \sf{2x = 16 + 6}}$

Add the numbers : 16 and 6

$\dashrightarrow{ \sf{2x = 22}}$

Divide both sides by 2

$\dashrightarrow{ \sf{ \frac{2x}{2} = \frac{22}{2} }}$

Calculate

$\dashrightarrow{ \sf{x = 11}}$

Hope I helped!

Best regards! :D
