First one: divide multiply 2(1x) which would equal 2x then do 2*3 then u would subtract 5 which should get you to the simplified form 2x+1

Second one: do 3(1x) which would equal 3x then do 7*3 which would equal 21 than do plus 3x which should get you to the simplified form of 6x+21

Third one: Do 4(1x) which equals 4x than do 4*2 which equals 8 than plus eight which should get you to the simplest form of 4x+16

Fourth one: do 4(1x) which would equal 4x then do 4*1 which equals 4 than subtract 6 which should get you to the simplest form of 4x-2

Fifth one: do 2(3x) which equals 6x then do 2*2 which equals 4 than subtract 5x which should get you to the simplest form of x+4

Sixth one: do 5(1x) which equals 5x than do 5*-4 which equals -20 than add 10 which gets you to the simplest form of 5x-10

the cost to rent a hall for school functions is 60$ per hour. write an expression for the cost of renting the hall for h hours.
Firlakuza [10]
The expression for the amount of time rented would be:
C=60(h), I choose this expression because C would stand for cost, 60 for the amount per hour, and h for the piece of expression being given. Now when you need to find the amount per hour, the brackets means to times; so you'd plug in the hour needed to be found in h, and times 60 by the hour.

Your table should look like this :
COST PER HOUR            |            HOURS            |            COST
$60                                    |                 2                  |         $60 x 2 = $120
$60                                    |                 6                  |         $60 x 6 = $360
$60                                    |                 8                  |         $60 x 8 = $480
$60                                    |                10                 |         $60 x 10 = $600
