Answer:10%= 310
5%= 155
15%=465
Step-by-step explanation: Solution for what is 15% of 3100
3100/x=100/15
(3100/x)*x=(100/15)*x - we multiply both sides of the equation by x
3100=6.66666666667*x - we divide both sides of the equation by (6.66666666667) to get x
3100/6.66666666667=x
465=x
x=465
<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
Y= —12/8x + 3 is the slope into form because 12x + 8y = 24 minus 12x on both sides . 8y= —12x + 24 divide 8y by 8y and —12x + 24 over 8 you will get y = —12/8x + 3
Solution: The commutative property of addition states that when two numbers are being added, their order can be changed without affecting the sum.
