Solve as much as you can and label the questions 1-3 :) What is the price of a letter that has the following weight?

1 ounce
1.1 ounces
0.9 ounce

A letter costs $0.92 to mail. How much did the letter weigh?
Kiran and Mai wrote some rules to represent the postage function, but each of them made some errors.

K(w)=⎧⎩⎨⎪⎪⎪⎪0.50,0.71,0.92,1.13,0 ≤w≤11≤w≤22≤w≤33≤w≤3.5

M(w)=⎧⎩⎨⎪⎪⎪⎪0.50,0.71,0.92,1.13,0

Identify the error in each person's work and write a corrected set of rules.

b) the dogs need to shift their focus to human scent.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

unless if u could do my questions, if not i wouldn't want to

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
