Answer:
Any equation with a slope greater than ²/₃
Step-by-step explanation:
Given table:
[tex]\begin{array}{| c | c |}\cline{1-2} x & y \\\cline{1-2} 3 & 2 \\\cline{1-2} 6 & 4 \\\cline{1-2} 9 & 6 \\\cline{1-2} \end{array}[/tex]
The unit rate is a ratio that compares the first quantity to one unit of the second quantity. The unit rate is also the slope of a linear equation.
Linear equation
[tex]y = mx + b[/tex]
where:
m is the slopeb is the y-interceptTo find the slope, take two ordered pairs from the table:
[tex]\sf let \: (x_1,y_1)=(3,2)[/tex]
[tex]\sf let \: (x_2,y_2)=(6,4)[/tex]
Substitute them into the slope equation:
[tex]\sf slope=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{4-2}{6-3}=\dfrac{2}{3}[/tex]
Therefore, the unit rate is ²/₃.
Any equation with a slope greater than ²/₃ is an equation with a greater unit rate than that represented in the given table.
Slope of table
(3,2)(6,4)Slope
m=4-2/6-3m=2/3Any equation having slope greater than 2/3 has higher unit rate than that of table

What is the greatest common factor of 253 and 345?
Answer:
23
Step-by-step explanation:
To find the Greatest Common Factor, or GCF, we need to factor the first 2 numbers and then find the greatest number that is both present in the prime factorization of both numbers.
253 = 1 * 11 * 23
345 = 3 * 5 * 23
Since 23 is both present in both numbers and is the greatest, the GCF of 253 and 345 is 23.
A box has the shape of a rectangle or prism with height 28 cm. If the height is increased by 0.3 cm, by how much does the surface area of the box increase?
Answer:
4.5cm
Step-by-step explanation:
28cm+0.3cm=28.3cm
surface area=28.3cm×15cm=424.5cm
original surface area=28cm×15cm=420cm
different=424.5cm-420cm=4.5cm

Step-by-step explanation:
Hello!
We can approach this system using the Elimination method. Since the coefficients of the the x terms are the same, we should vertically subtract the two equations.
Subtract[tex]\left \{ {{y=9x - 5} \atop {y = 9x + 6}} \right.[/tex][tex]-\left \{ {{y=9x - 5} \atop {y = 9x + 6}} \right.[/tex][tex]-\left \{ {{y=9x - 5} \atop {y = 9x + 6}} \right.\\0 = 0 -1 1[/tex][tex]0 \neq -11[/tex]Since 0 does not equal to -11, there are no solutions to the system.
We can also look at this graphically. The two lines have the same slope but different y-intercepts, meaning that they would be parallel lines with no intersection. If there is no intersection, there are no solutions.

(i) Equation : y = 6.25x + 65
(ii) Price of each ticket : $6.25
(iii) Money originally in the box : $65
Explanation:
Here from table, identify the coordinates given.
Coordinates:
(7, 108.75)(13, 146.25)(18, 177.50)Find slope:
[tex]\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} = \dfrac{\triangle y}{\triangle x} \ \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points[/tex]
[tex]\rightarrow \sf slope \ (m) : \dfrac{146.25-108.75}{13-7} = 6.25[/tex]
Slope is also the price of each ticket which is $6.25
Equation:
[tex]\sf y - y_1 = m(x - x_1)[/tex]
[tex]\rightarrow \sf y - 108.75 = 6.25(x - 7)[/tex]
[tex]\rightarrow \sf y - 108.75 = 6.25x - 43.75[/tex]
[tex]\rightarrow \sf y = 6.25x - 43.75 + 108.75[/tex]
[tex]\rightarrow \sf y = 6.25x +65[/tex]
To find the amount of money in the box originally, insert x which represents number of tickets sold as 0.
Originally amount of money:
[tex]\rightarrow \sf y = 6.25(0) +65[/tex]
[tex]\rightarrow \sf y = 65[/tex]
Hence, there were $65 in the box before any tickets were sold.

Answer:
Greater than
Step-by-step explanation:
you are adding exponent with the same denominator if its easier for you in this example you can set the denominator equal to 10.
Sum= adding
2/5 +4/5 =6/5 or 1 1/5
if you want to do it with the denominator equal to 10 just multiply each side by 2.
(2/5 +4/5)x 2
4/10 + 8/10 = 12/10
Daniel is a piano instructor who gives lessons on weekends. The cost of one lesson is $30. Daniel is offering a 5-lesson package with a 25% discount off the total price.
How much would a student save by buying a multi-pack compared to 5 separate lessons?
Why would Daniel offer a discount when he knows he could earn more money selling the lessons separately?
Answer:
150 is if you buy them separately but 150-25%=112 so 150-112=38 so students would save $38
Step-by-step explanation:
he made that package so that more people would go to his lessons know that there was a discount going on and more people would choose his lessons over people who don't have discounts.
Answer:
1- Separately - 150
2- students would save 38

Answer:
You divide both the numerator and the denominator by the same number until they can't be reduced any further.
Answer:
Make sure to divide the upper number and the lower number (in position) to a number which can't be futher divided. It will be of numbers which are really small numbers. like 4/2 will be divided by 2 to get the simplified answer of 1/2

Firstly, brainly allows 1 question per question. So do not try this again.
Lets make the fractions all like terms.
242/4 - 37/4=205/4. Lets now make this a mixed fraction.
By doing 205/4, we find out that 4 goes in less than 51 times.
1. 51 1/4.
2. 11/2 = 66/12.....so 66/12 - 29/12= 37/12. Make it mixed fraction: 3 1/12.
3. 36/5=72/10. 72/10 - 37/10 = 35/10. As a mixed it is 3 1/2
4. 35/3 - 17/2 can be rewritten by finding their GCM (Greatest Common Multiple). In this case it is 6.
70/6 - 51/6 = 19/6. 3 1/6.

Translate the following phrase to a mathematical expression.
a number times fifteen
(A) 15 n
(B) 15 + n
(D) 15 ÷ n
(C) n15
Answer:
I think C
Step-by-step explanation:
A number times fifteen would be n • 15 or just n15.
The reason it is not 15n is because it asks a "number" which in this case is represented by the letter n. That letter is now multiplied (times) by 15. So therefore the number "n" times 15 is n15.

( ? + 10 ) + 4 = 7 + ( 10 + 4 )
Answer:
x = 7

Step-by-step explanation:
( ? + 10 ) + 4 = 7 + ( 10 + 4 )
x + 10 + 4 = 7 + 10 + 4 (the answer is just 7)
x + 14 = 21
x = 21 - 14

Mary's desk was 67.94 inches long, Joe's desk was 78.26 inches long and Troy's desk was x inches long. If the length of all the desks combined was 214.62 inches, how long was Troy's desk?
Answer:
68.42
Step-by-step explanation:
We know that when we add the lengths of all of the desks together, the total is 214.62. Based on that information, we can set up the following equation: 67.94 + 78.26 + x = 214.62. From there, all you have to do is add 67.94 + 78.26 to get 146.2. Lastly, you simply do 214.62 - 146.2 to get 68.42. Hope this helps!

x = three over two and x = −4
x = 2 and x = −3

x = one half and x = one over three
Answer:
A
Step-by-step explanation:
2x² + 5x = 12
2x² + 5x - 12 = 0
x² + 5x - 24 = 0
factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24. the only pair that adds to 5 is 8 and 3
2x² - 3x + 8x - 12 = 0
split the equation and factor
2x² - 3x = 0 ||| 8x - 12 = 0
x(2x - 3) ||| 4(2x - 3)
therefore the pair is (2x - 3)(x + 4)
2x - 3 = 0
2x = 3
x = 3/2
or
x + 4 = 0
x = -4

Answer:
678.24
Step-by-step explanation:
First, we have to find the area of 1 cylinder(pi x r^2 x h), which i got as 226.08 then we multiply by 3 because there are 3 cylinders. 226.08 x 3 = 678.24
Answer: Hope this helps you!
678.24Step-by-step explanation:
First, I started off with the equation of the area of a cylinder
Area = π * radius^2 * height
Now I will go on and substitute
Area = 3.14 * 3^2 * 8
And now I will start solving
Area = 3.14 * 3^2 * 8
(3^2 = 3*3 = 9)
Area = 3.14 * 9 * 8
(9*8 = 72)
Area = 3.14 * 72
Area = 226.08
The area of 1 cylinder is 226.08, however we need to find the area of the whole composite figure which is made up of 3 cylinders.
226.08 * 3 = 678.24
