<h3>The number of beads lina has is 31</h3><h3>
Laura made a mistake by adding the constant 7 and variable 4b</h3>
<em><u>Solution:</u></em>
Given that,
Laura wrote and solved the following expression to find the total number of beads Lina has
There are 6 beads in each packet
7+4b = 11b
= 11(6)
=66
From given,
Lina has a total of 7 + 4b beads
Given that, There are 6 beads in each packet
Substitute b = 6
7 + 4(6)
Simplify
7 + 24
Add
31
Thus, she has a total of 31 beads and not 66 beads
Laura made a mistake by adding the constant 7 and variable 4b
But a constant and variable cannot be added
Step-by-step explanation:
volume = pi x radius² x height
okay so the cylinders diameter is 8 inches
diameter divided by 2 is radius so 8/2 = 4
so 3 times the radius will be 3x4 = 12
use the formula above and then you will get your answer
-9.5 because 1/2 simplifies to .5 and 9 is the whole number
