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 :
[tex]N=\dfrac{b-20}{4}[/tex]
Hence, this is the required solution.

Edward deposited $9,500 into savings account 2 years ago. The simple interest rate is 4%. How much money did Edward earn in interest ? What would be his new account balance
Answer:
$760 earned in intrest
$10260 new account balance
Step-by-step explanation:
First we have to find 4% of 9500
use the formuala
[tex]\frac{4}{100} =\frac{x}{9500}[/tex]
4×9500=38000
38000÷100=380
now 380×2=760
add 760 to 9500 for new account balance

Answer:
C. x=2.5, DC=7.5, EC=15
Step-by-step explanation:
since the triangles have congruent angles, the sides have a relationship too. Basically, the ratio between the triangle is 4:10 because those sides math up. So, that also means it is 2:5. Therefore, BC:EC=6:15. 15-12.5=2.5, so x=2.5.
Now you can just do 2.5+5=7.5 so DC=7.5
HELLO, plz answer this. Ming won 121 lollipops playing basketball at her school's game night. Later, She gave 48 to each of her friends. She only has 9 remaining. How many friends does she have? Write an equation for this problem and solve it with steps.
Answer:
Ming has 2 friends
(121-9)÷48= 2.3
You can´t split apart people.
First subtract 9 from 121 then divide by 48 to find how man friends Ming has.

What is the sum of the two solutions to the equation 3x2 - x = 4?
Answer:
The sum of the two solutions to the given equation is 1/3.
Step-by-step explanation:
Nature of Roots of a Second-Degree Equation
Given a quadratic equation:
[tex]ax^2 + bx + c = 0[/tex]
The roots of the equation are:
[tex]\displaystyle x_1=\frac{-b+ \sqrt{b^2-4ac}}{2a}[/tex]
[tex]\displaystyle x_2=\frac{-b- \sqrt{b^2-4ac}}{2a}[/tex]
The sum of the roots is:
[tex]\displaystyle x_1+x_2=-\frac{b}{a}[/tex]
The sum of the roots of a quadratic equation is equal to the negation of the coefficient of the second term, divided by the leading coefficient.
We are given the equation:
[tex]3x^2 - x = 4[/tex]
Rearranging:
[tex]3x^2 - x - 4=0[/tex]
The coefficient b is b=-1, and the leading coefficient is a=3, thus the sum of the roots is:
[tex]\displaystyle x_1+x_2=-\frac{-1}{3}[/tex]
[tex]\displaystyle x_1+x_2=\frac{1}{3}[/tex]
The sum of the two solutions to the given equation is 1/3.
Question 2 (2 points)
(08.06)
Using the graph below, calculate the average rate of change for f(x) from x = 0 to x=2.
a: x=-4
b: x=-2
c: x= 2
d: x= 4
Answer:
Option (D)
Step-by-step explanation:
Formula to get the average rate of change of the function f(x) between two points x = a and b is,
Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
We have to calculate the average rate of change between x = 0 and x = 2.
From the graph attached,
f(0) = -2
f(2) = 6
Therefore, average rate of change = [tex]\frac{6-(-2)}{2-0}[/tex]
= [tex]\frac{8}{2}[/tex]
= 4
Option (D) will be the correct option.

so sides are equal
so a=b= 25 m
Which pair of complex numbers has a real-number product?
O (1 + 2i) (8i)
0 (1 + 2i) (2 - 5i)
O (1 + 2i) (1 – 2i)
O (1 + 2i)(4i)
Answer:
(1 + 2i)(1 - 2i)
Step-by-step explanation:
Multiplying a complex number and its conjugate results in a real number.
Thus
1 + 2i and 1 - 2i are conjugates
(1 + 2i)(1 - 2i) ← expand using FOIL
= 1 - 2I + 2I - 4I² [ note i² = - 1 ]
= 1 - 4(- 1)
= 1 + 4
= 5 ← a real number

Prove that sin(x) + tan(x) = 1 + sec(x)/csc(x) by using trigonometric identities.
Answer:
Step-by-step explanation:
sin(x) + tan(x) =sin(X) + sin(x)/cos(x)
=sinx(1+1/cosx)
=Sinx(1+secx)
=1+secx/cosecx. (Since sinx=1/cosecx)
Hence LHS=RHS proved

If AC = 37 BC = 5x + 6, and AB = 2x + 3 Find BC
AC=37
BC=5X+6
AB=2X + 3
2x + 3 + 5x + 6 = 37
7x + 9 = 37
7x = 28
x = 4
BC = 5(4) + 6
BC = 26
Answer = BC = 26
A small company manufactures a certain item and sells it online. The company has a business model where the cost C, in dollars, to make x items is given by the equation
C = 20/3x + 50band the revenue R, in dollars, made by selling x items is given by the equation R = 10x . The break-even point is the point where the cost and revenue equations intersect.
Graph the cost and revenue equations on the xy-coordinate plane provided. Select the "Line" tool. Plot two points, then a line will connect the points.
9514 1404 393
Answer:
see attached
Step-by-step explanation:
The break-even point is on both curves. The y-intercept can be used for the other point in each case.
The break-even point is where cost and revenue are the same:
20/3x +50 = 10x
50 = 10/3x . . . . . . . . subtract 20/3x
15 = x . . . . . multiply by 3/10
r = c = 10(15) = 150 . . . . for x = 10
Two points you can use for graphing the lines are ...
cost: (0, 50) and (15, 150)
revenue: (0, 0) and (15, 150)

Write an equation in standard form of the line that passes through the given point
and has the given slope.
1. (2,-4), m= 2/3
2. (5, -3); m = 2
3. (6,0); m = 3/4
4. (-1, 2); m = 7
5. (-3,-5)m= 1/3
6. (4,0); m = -5
Answer:
y=2/3x-16/3
Step-by-step explanation:
ok ill show you how to do one question since the rest will take too long so what you do is
equation is y=mx+b right
so you have slope and these points (2,-4) and m=2/3
y=2/3x +b right
now all you do is sub in x and y which are ur given points
-4=2/3 (2) +b
now you solve for b
-4 = 4/3 + b
-4-4/3 = b
-12/3 - 4/3 = b
-16/3=b so therefore
y=2/3x-16/3
