The unit rate of 2.21 pounds/oh is use to express the relationship between pounds and kilograms. Charlie’s scale at home give weight in imperial units. According to the scale he weighs 156 pounds . What is Charlie’s weight in kilograms? Round to the nearest kilogram. Please help test

71

Step-by-step explanation:

Set up a proportional relationship

where k = Charlie's weight in kilograms

And remember 1 kilogram = 2.21 pounds

2.21/1 = 156/k

Cross multiply

2.21k = 156

Divide both sides by 2.21

k = 71 (rounded to the nearest whole )

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
