Answer:

Percent error = 4.29%

Step-by-step explanation:

Percent error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.

Mathematically, it is given by this expression;

$Percent \; error = \frac {experimental \;value - theoretical \; value}{ theoretical \;value} *100$

Given the following data;

Experimental value = 67

Theoretical value = 70

Substituting into the equation, we have;

$Percent \; error = \frac {67 - 70 }{ 70} *100$

$Percent \; error = \frac {3}{70} *100$

$Percent \; error = 0.04286 *100$

Percent error = 4.29%

for her book club, Sharon reads for 45 minutes each day. write an expression for the number of hours she reads in d days

Dafna1 [17]

N=(3/4)*h*d

--------------------

n=Number of hours she reads

h=Hour(s)

d=Days

--------------------

You see, with this formula - when d=2,

n=(3/4)*h*2=(6/4)*h=(3/2)*h=1.5 hours

So, in the space of 2 days, she had spent 1.5 hours reading.

Please don’t just comment for points

1. no because 2x+10 is not equal to 2x+7
2. no. you cant add una like terms so 4x+4 doesn’t equal 8x
3. yes. the terms still retain their same value although they are not in the same order
4. yes. when u distribute the -3, you get -3x-6 which is of course equal to -3x-6
