Gloria says the two expressions ¼ (12x + 24) - 9x and -6 (x+1) are equivalent. Is she correct? Explain how you know.
Answers
Answer: ✧･ﾟ: *✧･ﾟ:* No, they are not equivalent. *:･ﾟ✧*:･ﾟ✧
Step-by-step explanation:
♥*♡∞:｡.The first expression is equal to 3x + 24 - 9x, or 24 - 6x, and the second equation equals 6-6x. If you set them equal to eachother, you get 24 - 6x = 6 - 6x. The 6x's cancel out, so you're left with 24 = 6, which is not true. The expressions are not equivalent. ｡.｡:∞♡*♥
what is 3y mean in a math problem
Answers
Answer:
3y means 3 * y
Step-by-step explanation:
I think it is written as 3y instead of 3*y or 3 x y because, 3*y is a bit too cluttered, and 3xy or 3 x y means (Three times X times Y) because X is its own variable.
In other words, 3y means 3 times y
In any of the mathematical problem, the value of 3y will be 3 × y.
What is a mathematical problem?
A mathematical problem is any issue that may be modeled, examined, and potentially resolved using mathematical techniques. This can be a practical issue, like calculating the orbits of the solar system's planets, or a more theoretical issue, like Hilbert's conundrums.
In other cases, such as Russell's Paradox, it can also represent an issue with the very nature of mathematics. Building a mathematical model of the issue is typically the first step in applying mathematics to a real-world situation.
In order to translate the original problem into a mathematical one, it is necessary to abstract from the specifics of the problem, and the modeler must be careful not to lose key features in the process.
Therefore, in any of the mathematical problem, the value of 3y will be 3 × y.

An equilateral triangle has a perimeter of
24x + 6. What is the length of one side of the triangle?
Answers
Answer:
8x + 2
Step-by-step explanation:
The 3 sides of an equilateral triangle are congruent.
Divide the perimeter by 3 to find length of one side
[tex]\frac{24x+6}{3}[/tex]
= [tex]\frac{24x}{3}[/tex] + [tex]\frac{6}{3}[/tex]
= 8x + 2
Answer: if these expression represent side lengths, then you simply add those three expressions, and that's the perimeter.

Answer: x = 7
Step-by-step explanation:
Put both angles in an equation that equals 90 degrees
5x + 55 = 90
subtract 55 from both sides
5x = 35
divide by 5
x = 7
Now check if its true.
5(7) + 55 = 90
35 + 55 = 90

Linda has to buy stickers, erasers, and a pencil. She can only spend $3. A sticker costs $0.35, an eraser costs $0.99, and a pencil costs $0.59. Can Linda buy 3 stickers and 2 erasers?
[Use the inequality 0.35x + 0.99y + 0.59 ≤ 3]
Yes, because the total will be $1.62
Yes, because the total will be $2.93
No, because the total will be $3.62
No, because the total will be $5.93
Answers
Answer:
No, because the total will be 3.03 + 0.59 = £3.62
Step-by-step explanation:
0.35 x 3 = 1.05
0.99 x 2 = 1.98
1.05 + 1.98 = 3.03 = $3.03 without pencil (0.59)
= 1.05 + 1.98 = 3.03 ≤ 3 is incorrect as 3.03 should be the maximum equal to or appear the other way round.
Inequality for all 6 items using the same inequality shown 0.35x+0.99y+0.59< 3 is incorrect No, because the total will be 3.03 + 0.59 = £3.62
and inequality of higher amounts than $3 should be shown other way round where ≤ 3 means it stops at $3 and is less or equal.
and inequality facing towards means it would be equal but more than $3

A solution to the equation x^3 + 2x - 25 = 0 lies between 2 and 3. Find this solution correct to 1 decimal place
:))
Answers
The solution to the equation x^3 + 2x - 25 = 0, correct to 1 decimal place, is approximately x = 2.7.
To find the solution to the equation x^3 + 2x - 25 = 0, we can use numerical methods such as the bisection method or Newton's method. Let's use the bisection method to find the solution between 2 and 3.
Evaluate the equation at the lower and upper bounds:
f(2) = (2)^3 + 2(2) - 25 = 8 + 4 - 25 = -13
f(3) = (3)^3 + 2(3) - 25 = 27 + 6 - 25 = 8
Check if the function changes sign between the lower and upper bounds:
Since f(2) is negative and f(3) is positive, we can conclude that there is at least one root between 2 and 3.
Perform iterations of the bisection method:
Divide the interval [2, 3] into two equal halves:
Lower bound: a = 2, Upper bound: b = 3
Midpoint: c = (a + b) / 2 = (2 + 3) / 2 = 2.5
Evaluate the function at the midpoint:
f(c) = (2.5)^3 + 2(2.5) - 25 = 15.625 + 5 - 25 = -4.375
Check the sign of f(c):
Since f(c) is negative, we update the lower bound to c, as the solution lies between the lower bound and c.
Repeat the steps with the new interval [2.5, 3]:
Lower bound: a = 2.5, Upper bound: b = 3
Midpoint: c = (a + b) / 2 = (2.5 + 3) / 2 = 2.75
Evaluate the function at the new midpoint:
f(c) = (2.75)^3 + 2(2.75) - 25 = 20.796875 + 5.5 - 25 = 1.296875
Check the sign of f(c):
Since f(c) is positive, we update the upper bound to c, as the solution lies between c and the upper bound.
Repeat the steps until the desired level of precision is achieved:
Continue dividing the interval and evaluating the function at each midpoint until the interval becomes sufficiently small.
Continue the bisection method iterations:
Repeat the steps until the interval is small enough:
[2.5, 2.75]
[2.625, 2.75]
[2.6875, 2.75]
[2.71875, 2.75]
[2.734375, 2.75]
[2.734375, 2.7421875]
The final interval [2.734375, 2.7421875] contains the solution.
Therefore, the solution to the equation x^3 + 2x - 25 = 0, correct to 1 decimal place, is approximately x = 2.7.
