Tim is measuring the weight (in ounces) of a substance for a science experiment. Tim added a mystery substance (m) to his experiment. Tim used the equation 12.93 + m = 17.0 to find out how much he added. How much of the mystery substance (m) did Tim add to his experiment?
A) 4.07 ounces
B) 4.97 ounces
C) 5.03 ounces
D) 5.17 ounces

A) 4.07 ounces

Step-by-step explanation:

12.93 + m = 17.0

Subtract 12.93 from both sides of the equation.

12.93 - 12.93 + m = 17.0 - 12.93

m = 4.07

A) 4.07 ounces

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

you ignore the remainder, therefore the answer is y = x+2

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
