72x+12y=60
To find the equivalent equations, follow the steps below
Multiply the equation 72x+12y=60 by 10
10(72x) + 10(12y) = 10(60)
720x + 120y = 600
Divide the equation 72x+12y=60 by 12
(72x/12) + (12y/12) = 60/12
6x + y = 5
y = 5 - 6x
Divide the equation 72x+12y=60 by 72
(72x/72) + (12y/72) = 60/72
x + y/6 = 5/6
x = 5/6 - y/6

On Roberto’s shelf he has 6 mystery books, 5 science fiction, 4 history and 3 adventure. Roberto will randomly choose 1 book to read. What is the probability that he will choose an adventure book?
Answer:
3/18, or simplified, he has a 1/6 chance of grabbing an adventure book.
Step-by-step explanation:
6 + 5 + 4 + 3 = 18. There's 3 adventure books, which makes it so that he has a 3/18 chance of it being an adventure book. How did I simplify? 18 ÷ 3 = 6, 3 ÷ 3 = 1.
Show that each of the following values for the given variable is a solution to the
given equation. Show the calculations that lead to your answer.
(a) 3x + 4 = 7
for x = 1
Part a)
Answer:
As the L.H.S = R.H.S, so [tex]x = 1[/tex] is the solution to the equation [tex]3x + 4 = 7[/tex]
Step-by-step explanation:
Given the equation
[tex]3x + 4 = 7[/tex]
solving the equation for x = 1
substituting the value of x = 1 in the equation
[tex]3\left(1\right)+\:4\:=\:7[/tex]
[tex]7=7[/tex]
As the L.H.S = R.H.S, so [tex]x = 1[/tex] is the solution to the equation [tex]3x + 4 = 7[/tex]
Part b)
Answer:
As the L.H.S = R.H.S, so [tex]x = 15[/tex] is the solution to the equation [tex]\frac{x-3}{2}=6[/tex]
Step-by-step explanation:
Given the equation
[tex]\frac{x-3}{2}=6[/tex]
solving the equation for x = 15
substituting the value of x = 15 in the equation
[tex]\frac{15-3}{2}=6[/tex]
[tex]\frac{12}{2}=6[/tex]
[tex]6=6[/tex]
As the L.H.S = R.H.S, so [tex]x = 15[/tex] is the solution to the equation [tex]\frac{x-3}{2}=6[/tex]
Part c)
Answer:
As the L.H.S = R.H.S, so x = -3 in the equation is the solution to the equation [tex]x^2=-2x+3[/tex]
Step-by-step explanation:
Given the equation
[tex]x^2=-2x+3[/tex]
solving the equation for x = -3
substituting the value of x = -3 in the equation
[tex]x^2=-2x+3[/tex]
[tex]\left(-3\right)^2=-2\left(-3\right)+3[/tex]
[tex]9 = 6 + 3[/tex]
[tex]9 = 9[/tex]
As the L.H.S = R.H.S, so x = -3 in the equation is the solution to the equation [tex]x^2=-2x+3[/tex]
A company's current stock price is $50.00 and its most recent dividend was $2.00 per share. Since analysts estimate the company will have a 5 percent growth rate, what is its expected return?
Answer:
Expected rate of return =7.1% (Approx.)
Step-by-step explanation:
Given:
Current stock price = $50
Divided d = $2
Growth rate g = 5 %
Find:
Expected rate of return
Computation:
Expected rate of return = D(1+g)/Current Price + g
Expected rate of return = [2(1+5%)/50] + 5%
Expected rate of return =7.1% (Approx.)

Your class is selling chocolates and caramel corn. Boxes of
chocolate sell for $6 each and bags of caramel corn sell for
$5 each. A total of 535 items were sold and $2889 was
raised. How many of each item was sold?
O 321 boxes of chocolate, 214 bags of caramel corn
o 214 boxes of chocolate, 321 bags of caramel corn
O 343 boxes of chocolate, 192 bags of caramel corn
0 211 boxes of chocolate, 324 bags of caramel corn
214 boxes of chocolate, 321 bags of caramel corn item was sold.
How many of each item was sold?Boxes of chocolate sell for $6 each and bags of caramel corn sell for
$5 each. A total of 535 items were sold and $2889 was
raised.
set of of chocolate was sold x boxes,
because a total of 535 items more sold .
so the caramel corn was sold (535 -x) bags,
and boxes of chocolate sell for $6 each , bags of caramel corn for each and $2889 was raised.
so 6 x+ 5.(535-x) = $2889.
6 x+ 5.535-x = $2889.
6 x+ 2675 - 5x = $2889.
6x - 5x =2889-265
x =214
so the caramel corn was sold 535-x =535-214 = 321
214 boxes of chocolate, 321 bags of caramel corn was sold.

Caramel corn bags cost $5 apiece, while chocolate boxes cost $6 each. 535 products in total were sold, bringing in a total of $2889 then there exists 214 boxes of chocolate, 321 bags of caramel corn was sold.
How to estimate the value of x?Any one of the forms, including addition, subtraction, multiplication, and division, should be used for the algebraic expression. Bring the variable to the left side and the other values to the right side in order to find the value of x. To find the answer, simplify the values.
Let set of of chocolate was sold x boxes,
because a total of 535 items more sold .
so the caramel corn was sold (535 - x) bags, and boxes of chocolate sell for $6 each , bags of caramel corn for each and $2889 was raised.
From the given information, we get
6x + 5(535 - x) = $2889
simplifying the above equation, we get
6x + 5 × 535 - 5x = $2889
6x + 2675 - 5x = $2889
6x - 5x = 2889 - 265
x = 214
So the caramel corn was sold = 535 - x
Substitute the value of x in the above equation, we get
= 535 - 214
= 321
There exists 214 boxes of chocolate, 321 bags of caramel corn was sold.
Therefore, the correct answer is option b) 214 boxes of chocolate, 321 bags of caramel corn.

Consider the right triangle below.
6x - 44
2x - 20
3x + 24
If the perimeter of the triangle is 224 cm, find the area of the triangle.
The area of the triangle is
cm
Answer:
Area = 1,344 cm²
Step-by-step explanation:
First, find the value of x and the numerical side length of all sides of the triangle before finding the area.
Thus:
Perimeter of a triangle = sum of all its side
Therefore,
(6x - 44) + (2x - 20) + (3x + 24) = 224
Solve for x
6x - 44 + 2x - 20 + 3x + 24 = 224
Add like terms
11x - 40 = 224
Add 40 to both sides
11x = 224 + 40
11x = 264
Divide both sides by 11
x = 24
Find the measurement of each side length by plugging in the value of x:
Hypotenuse = 6x - 44 = 6(24) - 44 = 100 cm
Height = 2x - 20 = 2(24) - 20 = 28 cm
Base = 3x + 24 = 3(24) + 24 = 96 cm
Find the area:
Area = ½×base×height
Plug in the values
= ½×96×28
Area = 1,344 cm²

In rectangle ABCD, diagonals AC and BD intersect at E. If AE=3x-28 and DE=.5x+12, find the length of AC.
Given:
In rectangle ABCD, diagonals AC and BD intersect at E, AE=3x-28 and DE=.5x+12.
To find:
The length of AC.
Solution:
We know that, diagonals of a rectangle are equal and they bisect each other.
In rectangle ABCD, diagonals AC and BD intersect at E, so
[tex]AE=BE=CE=DE[/tex] ...(i)
Taking [tex]AE=DE[/tex], we get
[tex]3x-28=0.5x+12[/tex]
[tex]3x-0.5x=28+12[/tex]
[tex]2.5x=40[/tex]
Divide both sides by 2.5.
[tex]x=\dfrac{40}{2.5}[/tex]
[tex]x=16[/tex]
Now,
[tex]AE=3x-28[/tex]
[tex]AE=3(16)-28[/tex]
[tex]AE=48-28[/tex]
[tex]AE=20[/tex]
Using segment addition property,
[tex]AC=AE+CE[/tex]
[tex]AC=AE+AE[/tex] [Using (i)]
[tex]AC=20+20[/tex]
[tex]AC=40[/tex]
Therefore, the length of AC is 40 units.
A. 3(x + 2) = 18
B. X + 2 = 18
Answer:
A. x=4
B. x=16
Step-by-step explanation:
A. multiply out: 3x+6=18
subtract 6 from both sides: 3x=12
divide both sides by 3: x=4
B. subtract 2 from both sides: x=16
Paul says that (3.14 X 10^5) + (2.53 X 10^4) = 5.67 X 10^5. Is Paul correct? Explain.
PLEASE I NEED HELP WITH THIS ASAP
Paul is wrong as first he has to convert their powers to the same value with base 10.
What is scientific notation?We use the scientific notation of numbers to write very large numbers in compact form.
In the scientific form, we write a number in the form of base×10ⁿ.
Where 0 ≤ base < 10 and n can be any rational number.
Given, Paul says (3.14 X 10⁵) + (2.53 X 10⁴) = 5.67 X 10⁵. he is wrong to add bases they must have the same power of 10.
∴ (3.14 X 10⁵) + (2.53 X 10⁴).
= (31.4 X 10⁴) + (2.53 X 10⁴).
= 33.93 X 10⁴.

If Y (-7,-4) and (5,2), find the slope of a line perpendicular to YZ. Please help if you can
Answer:
-2
Step-by-step explanation:
The slop of YZ is 1/2. The slope perpendicular would be opposite, making it -2.
Answer:
- 2
Step-by-step explanation:
Calculate the slope m of YZ using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = Y(- 7, - 4) and (x₂, y₂ ) = Z(5, 2)
m = [tex]\frac{2+4}{5+7}[/tex] = [tex]\frac{6}{12}[/tex] = [tex]\frac{1}{2}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{2} }[/tex] = - 2
