Bob estimates that her bother me is 4 feet tall when they get measured at the doctor’s office her brother actual height is 3 Feet, 10 inches

What was the error, expressed in inches?

What was the error , expressed as a percentage of the actual height ?

it is x=-4

step-by-step explanation:

should have been evaluated with one odd value and one even value. the expressions have equivalent values when . when , the first expression has a value of 3 and the second

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
