Ahamburger bun merchant can ship 8 large boxes or 10 small boxes of hamburger buns into a carton for shipping. in one shipment, he sent a total of 304 boxes of hamburger buns. if there are more large boxes than small boxes, how many cartons did he ship?

34 total        16 small 18 large

Step-by-step explanation:

1 small box*10 = 10        304-10=294 (NOT DIVISIBLE INTO 8)

2small boxes*2 = 20     304-20 = 284  (not divisible into 8)

16 small boxes*10 = 160        304-160 =144 (YES DIVISIBLE INTO 8)

                                                    144/8 =18  (18 large boxes)

16*10 = 160

18*8=144        

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
