Answer:

Step-by-step explanation:

let the integers be x and y

x+y=-20

y=-20-x

xy=99

x(-20-x)=99

-20x-x²=99

x²+20x+99=0

x²+11x+9x+99=0

x(x+11)+9(x+11)=0

(x+11)(x+9)=0

x=-11,-9

when x=-11

-11+y=-20

y=-20=11=-9

when x=-9

-9+y=-20

y=-20+9=-11

so integers are -11,-9

Kg to Pounds

8.3 kg in ponds is 18.26 lb

Kg to Ounces

8.3 kg in ounces is 292.16 oz

Step-by-step explanation:

We need to convert 8.3 kg to pounds and ounces

The conversion ratio is:

1 lb = 16 oz
1 kg = 2.2 lb

Converting kg to pounds(lb)

We know 1 kg = 2.2 lb

So, 8.3 kg = 8.3*2.2 lb

8.3 kg = 18.26 lb

So, 8.3 kg in ponds is 18.26 lb

Converting kg to ounces (oz)

We know that: 1 lb = 16 oz

We have converted 8.3 kg into 18.26 lb (pounds)

So, 1 lb = 16 oz

18.26 lb = 18.26*16 oz

18.26 lb =292.16 oz(ounces)

So, 8.3 kg in ounces is 292.16 oz
