The total weight for the
murderer, x, and his/her luggage, y, was 230lbs. The
weight of the murderer was 10lbs less than twice the
weight of the luggage.
Equations
Answer:
x=110lbs and y=120lbs
Step-by-step explanation:
[tex]Solution,\\\\x+y=230lbs\\\\[/tex]
When the weight of x is 10lbs less than y,
Then,
[tex]x=y-10lbs[/tex]
Now we have,
[tex]\hookrightarrow x+y=230lbs\\\\\hookrightarrow (y-10lbs)+y=230lbs\\\\\hookrightarrow 2y-10lbs=230lbs\\\\\hookrightarrow 2y=230lbs+10lbs\\\\\hookrightarrow 2y=240lbs\\\\\hookrightarrow y=240lbs/2\\\\\hookrightarrow y=120lbs[/tex]
Again,
As x=y-10lbs
Then,
[tex]\hookrightarrow x=y-10lbs\\\\\hookrightarrow x=120lbs-10lbs\\\\\hookrightarrow x=110lbs[/tex]

A cereal box in the shape of a rectangular prism has a volume of 18x^3 - 3x^2 - 6x. What are three possible linear expressions for the dimensions of the cereal box?
From factoring, the volume of a rectangular prism can be written as:
3x * (2x+1) * (3x-2).
FactoringIn math, factoring or factorization is used to write an algebraic expression in factors. There are some rules for factorization. One of them is a factor out a common term for example: x²-x= x(x-1), where x is a common term.
The question gives: 18x³-3x²-6x. You can see that, initially, 3x is a common term. Therefore, you can write: 3x * (6x²-x-6) . Nonetheless, the question also asks 3 linear expressions, here only you have one (3x).
Thus, you should factor the expression (6x²-x-6) into two linear expressions: (2x+1)* ( 3x-2).
Thus, the volume of a rectangular prism can be written as:
3x * (2x+1) * (3x-2)

Which equation is y = (x 3)2 (x 4)2 rewritten in vertex form?
The vertex form of the provided equation y = (x 3)2 (x 4)2 is expressed as (x+3.5)²+0.5.
What is the vertex form of parabola?Vertex form of parabola is the equation form of quadratic equation, which is used to find the coordinate of vertex points at which the parabola crosses its symmetry.
The standard equation of the vertex form of parabola is given as,
y=a(x-h)^2+k
Here, (h, k) is the vertex point.
The given equation is
[tex]y = (x +3)^2 +(x+ 4)^2\\y=x^2+9+6x+x^2+16+8x\\y=2x^2+14x+25[/tex]
To convert this equation, into the vertex form, follow the following steps,
[tex]y=2(x^2+7x+12.5)\\y=2((x+3.5)^2-12.25+12.5)\\y=(x+3.5)^2+0.5[/tex]

If –3 i is a root of the polynomial function f(x), which of the following must also be a root of f(x)? –3 – i –3i 3 – i 3i
If -3 + i is a root of the polynomial function f(x), -3 - i must also be a root of f(x)
How to determine the true statement?The root of the polynomial function is given as:
-3 + i
The above root is a complex root.
If a polynomial has a complex root, then the conjugate of the root is also a root of the function
The conjugate of -3 + i is -3 - i
Hence, if -3 + i is a root of the polynomial function f(x), -3 - i must also be a root of f(x)

What are similar figures?This characteristic is referred to as resemblance or comparable figures when two or more items or figures appear to be the same or equal based on their shapes. These figures always superimpose one another regardless of how they are magnified or diminished. When two shapes, such triangles, polygons, or quadrilaterals, have the same dimension or common ratio but a different size or length, they are referred to as comparable figures in geometry.
Given quadrilateral's are similar
ABCD ≈ EFGH
for similarity the angles of both figures are equal and ratio of length of their sides are equal,
so AB/EF = BC/FG = CD/GH = DA/HE
we have AB = 3, EF = 2
CD = 4.5 and GH = y
substitute the values
3/2 = 4.5 /y
y = (4.5 x2)/3
y = 3 units.
Hence the measure of y is 3 units.

You and your friends go to the diner and order burgers and drinks. Each burger costs $8.00 and one soda costs $2.50. Combined, you and your friends order twice as many burgers as you do sodas, s.
a. Write an algebraic expression that represents the number of hotdogs you and your friends want to buy.
b. Combined, you and your friends can spend no more than a $100 gift card. Write an inequality that represents the number of burgers and sodas you and your friends can buy.
C. Solve your inequality from part b. and state the maximum number of sodas that can be purchased.
The answers to your questions are as we have them below:
a. s ( 2 burgers + 1soda )
b. s ( $16.00 + $2.50) ≤ $100
c. The maximum number of sodas that can be purchased is 5.40 sodas
Algbraic expressionAn algebraic expression is an expression containing integer constants, variables and algebraic operations
Detailed solution of the above is given below:
One Burger costs $8.00
One soda costs $2.50
Combined = s (2burgers + 1soda)
where s is the number of persons ordering.
a. s ( 2 * $8.00 + $2.50 )
s ( $16.00 + $2.50) = s($18.50) assuming that the hotdogs will be the total amount to be spent
b. if the cant spend more than a $100 gift card, the inequality will be
s ( $16.00 + $2.50) ≤ $100
s($18.50) ≤ $100
s ≤ [tex]\frac{100}{18.50}[/tex] = 5.40
Therefore the number of burgers and soda they can buy is
5.40 (2burgers + 1soda) = 10.80 burgers and 5.40sodas
c. s ( $16.00 + $2.50) ≤ $100
s($18.50) ≤ $100
s ≤ [tex]\frac{100}{18.50}[/tex] = 5.40
The maximum number of sodas that can be purchased is 5.40 sodas
In conclusion, the algebraic expression for the orders you and your friends will make combined is: s ( 2 burgers + 1soda )

Answer:
For 36 hours, that would be 792 quarts. The unit rate is 528 quarts per day.
