11. Let's assume that Ryan has x stamps, so Charlie has 5x stamps.

Set up the equation:
x + 5x = 1,608 
6x = 1,608
x= 268

So Ryan has 268 stamps, and Charlie has 5*268 = 1340 stamps

12. You already calculated how many monitors he sold which is 33.

Multiply : 185 * 33 = $6105 

(you might have done something wrong when multiplying :) )

Marcus has $28 to spend. He spent $3.75 to buy a notebook. He needs to save $11.25 but he wants to buy a snack. Chips cost $1.30
Alborosie

Total money Marcus has = $28

Money spent to buy a notebook = $3.75

Money left now = 28-3.75=24.25

Money needed to be saved = $11.25

So, the amount of money Marcus can spend = 24.25-11.25=13

Cost of a packet of chips = $1.30

The inequality to determine the maximum number of chips he can buy is:

Let the number of chips Marcus can buy = x

As he cannot spend more than $13 to buy chips so equation becomes:

1.30x\leq 13

Solving this we get

x\leq 10

Hence, Marcus can buy a maximum of 10 packs of chips and  save $11.25

What is the simplified expression for 6 (2 (y x))? 6 y 12 x 12 y 12 x 12 y 8 x 8 y 8 x
stellarik [79]

The simplified expression for 6(2( y + x)) is 12y + 12x.

Accordin to the given question.

We have an expression

6(2( y + x))

Therefore,

The simplified expression for 6(2( y + x)) is given by

6(2(y + x))

= 6(2y + 2x)          (by distributive law)

= 12y + 12x              (by distributive law)

Hence, the simplified expression for 6(2( y + x)) is 12y + 12x.
