Given :
Liam has a bag of b beads.
He gives 20 beads to his sister.
He then makes 4 necklaces with the same of beads on each necklace using all of the remaining beads.
To Find :
Write an expression that represents the number of beads on each necklace.
Solution :
Number of necklace remains after giving 20 beads to his sister is ( b - 20 ).
Number of beads on each necklace using all of the remaining beads is :
Hence, this is the required solution.

Determine the smallest dimension to use
To answer this question, I'll make use of the attached figure as a point of reference.
The area of the printed matter is:
Substitute 150 for A1
Make H the subject
The area of the full paper is:
Substitute 150/W for H
Open brackets
Collect Like Terms
Differentiate with respect to w and set the result to 0
Set to 0
Collect Like Terms
Cross Multiply
Make the subject
Take positive square root of both sides
Recall that:
Hence, the smallest dimension of the paper is:
Answer:
30
Step-by-step explanation:
Given the equation;
n/10 + 7 = 10
We are to find the value of n
Subtract 7 from both sides
n/10 + 7 - 7 = 10 - 7
n/10 = 3
Cross multiply
n = 10 * 3
n = 30
<em>Hence the solution to the equation is 30</em>

Answer:
A. X < 3
Step-by-step explanation:
Let x represent the average number of shots Kaydence can take on each hole in order to beat Delilah's score.
Delilah final score is 42 while Kaydence has 5 holes left and has a score of 27. Hence:
number of holes left for Kaydence * x < Delilah final score - Kaydence present score
That is:
5*x < 42 - 27
Simplifying gives:
5x < 15
Dividing both sides by 5 to make x the subject of the inequality:
5x / 5 < 15 / 5
x < 3
IR = 12 |divide both sides by I ≠ 0
R = 12/I
R(I) = 12/I where I ≠ 0.
