Jeremy weighs 240 pounds and his best friend steven weighs 2,080 ounces. how many kilograms do they weigh? (the conversion factors are 16 ounces/pound and 2.2 pounds/kilograms. round to the nearest hundredth.)

a. 168.18 kilograms
b. none of these
c. 168.82 kilograms
d. 370 pounds

168.18 kg

Step-by-step explanation:

Jeremy weighs 240 lbs2.2 lbs = 1 kg

240 / 2.2 = 109.09 kg

Steven weighs 2080 oz16 oz = 1 lb

2080 / 16 = 130 lbs

130 / 2.2 = 59.09 kg

together, they weigh : (109.09 + 59.09) = 168.18 kg <==

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

i think the answer is b
