Two third of a number is greater than one third of the number by 5. The number is ________
Answers
Let's assume the number as x
→ ⅔rd of x =( ⅔)x
Now ⅔ of x is greater than ⅓ of 5 .
\( \sf{ \implies \: \dfrac{1}{3} \times 5 = \dfrac{5}{3} } \)
\(\sf{ \implies \: \dfrac{2}{3} \times x > \dfrac{5}{3} } \)
\(\sf{ \implies \: x > \dfrac{5}{3} \times \dfrac{3}{2} }\)
\(\sf{ \implies \: x > \dfrac{5}{2} }\)
So number will be greater than 5/2 .

Answers
Answer:
1. 4
2. 3,4
3. 5,2
Step-by-step explanation:
A term is anything except operations so for example 14y would be one and a coefficient is the number before the variable so 3 and 14. And a constant is a number by itself with no variable so 5 and 2.
2. Coefficients are 3y(squared) and 14y
(Coefficients are the numbers with variables)
3. Constant is 9
A constant is a number that has no variables.
Four more than half of the students in Bryan’s homeroom have tickets to attend the school’s musical. 20 students from that class have tickets. Select all the equations that can be used to find the number of students, m, in Bryan’s homeroom.
CHECK IMAGE!!
Answers
The options b and d are suitable equations. The equations are \(\frac{1}{2} m+4=20 and 4=20-\frac{1}{2}m\). The number of students in Bryan's homeroom in this equation is m.
The following information is given in the question: The number of students who possess tickets = 20. And, m is the number of students in Bryan's homeroom. let us solve the sum using this particular equation \(\frac{1}{2} m+4=20\) to figure out how many students are in Bryan's homeroom.
On solving the given equation,
\(\frac{1}{2} m+4=20 \\4+\frac{2}{m} = 20\\8+m=40\\m= 40-8 = 32. \\\)
As a result, there are 32 students in Bryan's homeroom(m). The options that are used to find the number of students, m, in Bryan’s homeroom are \(\frac{1}{2} m+4=20\) and \(4=20-\frac{1}{2}m\). All other options do not satisfy the conditions given in the question.

HELP!!
is 50.24 and 50.23 rational or irrational numbers pls explain pls pls
its easy i know but my brain hurts
Answers
Answer:
50.23 and 50.24 are both rational numbers.
Step-by-step explanation:
Rational numbers can be written like a ratio.
●Whole numbers (2, 15, 77) are rational bc just put a 1 underneath it (2/1, 15/1, 77/1) now its a ratio.
●Fractions are rational bc the fraction is exactly the ratio (1/2, 5/8, 65/111)
●Decimals that "terminate" that is end or stop are rational like your problem (50.23, 50.24) and ALSO decimals that repeat (2.33333..., 7.666666...) We can do some math on these and find the ratio that is equal to the decimal.
50.23
= 50 + 23/100
= 50•(100/100) + 23/100
= 5000/100 + 23/100
= 5023/100
50.23 is equal to 5023/100.
50.24 = 5024/100 = 2512/50 = 1256/25
Briefly, decimals that do not end either with no pattern or even with a pattern, but not repeating...they are Irrational. (pi, e, and any weird 4.531874569131187732678...no pattern, and 3.1121231234pattern but not a repeat)
Square roots of not-a-perfect square are Irrational (sqrt3, sqrt7, sqrt24) probably tmi, but hope this helps!

Write the math sentence as an equation: Negative eight times the sum of a number and 14.5 is 64.5
−8(r − 14.5) = 64.5
−8r + 14.5 = 64.5
−8(r + 14.5) = 64.5
−8r − 14.5 = 64.5
Answers
Answer:
The correct equation is −8(r + 14.5) = 64.5
Step-by-step explanation:
This equation states that negative 8 times the sum of a number (r) and 14.5 is equal to 64.5.
The other equations are not correct because they do not correctly represent the given statement. In equation 1, the minus sign is in the wrong place, and in equation 3, the minus sign is missing before the 14.5. In equation 4, the minus sign is missing before the 8.
I hope this helps. Let me know if you have any further questions.
You start with -8, then to multiply it my a sum you need to put that addition equation in parentheses so -8(r+14.5), then we know the whole thing is equal to 64.5, so -8(r+14.5)=64.5
By process of elimination: We know A is not correct because it has a subtraction problem in the parenthesis, and we know it should be addition because of the key word “sum” with refers to an addition problem.
We know B is not correct because there are no parenthesis, and since we need to multiply -8 to the sum/total of the addition problem, it wouldn’t work without parenthesis.
We know D is not correct for the same reasons as A and B, there are no parenthesis and there is not addition sign
I’m knew to this, and I tried to simplify my answer so if you need any clarification let me know! Good luck!

Determine the number of solutions to the system of linear equations shown on the graph.
coordinate plane with one line that passes through the points 0 comma 2 and 1 comma 0 and another line that passes through the points 0 comma negative 1 and 1 comma negative 2
Answers
This answer was generated by an AI and may be incorrect.
The number of solutions to a system of linear equations can be determined by finding the point where the lines intersect. If the lines intersect at exactly one point, the system has a unique solution. If the lines are coincident, the system has infinitely many solutions. If the lines are parallel, the system has no solution.
From the graph, we can see that the two lines intersect at exactly one point, which means that the system of linear equations has a unique solution.
That is where both lines intersect, therefore that is the solution.

An image of a rhombus is shown.
a rhombus with a base of 18 centimeters and a height of 15.5 centimeters
What is the area of the rhombus?
16.75 cm2
33.5 cm2
139.5 cm2
279 cm2
Answers
Formula used,
Area of rhombus = Base × height
Substituting the values,
\( \longrightarrow\)Area = 18 × 15.5
\( \longrightarrow\) Area = 279 cm²
Therefore, 279 cm² is the area of the rhombus .
Answer:
D) 279 cm²
Step-by-step explanation:
Area of a rhombus formula:
\(A=bh\)
This formula is also used for squares and rectangles.
So, we can substitute in our values such as:
A=(18)(15.5)
simplify
A=279
Now, add our label and units:
A=279 cm²
