Answer:
225 for finn jake gets 175
Step-by-step explanation:
400 divided by 2 = 200+25 witch gives Finn 225 dollars.
J=175 f=225
Answer:
F = 212.5
J = 187.5
Step-by-step explanation:
My way is weird but i divided each side by 2 and subtracted 25 from jake and added 25 to finn. Then distributed 25 for each.
ex: 175 + 12.5 = 187.5.
225 - 12.5 = 212.5.
Add them both and you get 400.

Who started the problem correctly? The problem form is (-5) - (-1 3/4).
Mariah started the problem as (-5) + 1 - 3/4
Shane started the problem as (-5) + 1 + 3/4
Answer:
Shane started the problem correctly
Step-by-step explanation:
We are given problem (-5) - (-1 3/4).
Mariah started the problem as (-5) + 1 - 3/4
Shane started the problem as (-5) + 1 + 3/4
We need to find who started the problem correctly.
The problem should be started by converting the mixed fraction into improper fraction i,e
[tex]-5-(-1\frac{3}{4})\\=-5-(-1-\frac{3}{4} )\\=-5-(-\frac{7}{4})[/tex]
Now we will solve bracket by multiplying -1 with term inside the bracket i.e
[tex]=-5+\frac{7}{4}[/tex]
[tex]= \frac{-13}{4}[/tex]
Let's compare both the procedures now:
Mariah:
[tex](-5) + 1 - \frac{3}{4}[/tex]
[tex]=(-5) - \frac{1}{4}[/tex]
[tex]=\frac{-21}{4}[/tex]
Therefore, Mariah did not start the problem correctly.
Shane:
[tex](-5) + 1 + \frac{3}{4}[/tex]
[tex]= -5 + \frac{7}{4}[/tex]
[tex]= \frac{-13}{4}[/tex]
Therefore, Shane started the problem correctly.

Step-by-step explanation:
The tables of ordered pairs represent points on the graphs of Equation 1 and Equation 2. Which system of equations is represented by these two tables? A) 4x + y = 24 2x + 2y = 4 B) X + 4y = -24 x - y = -4. x - 4y = 24 x + y = 4 D) 4x - y = 24 2x - 2y = 4
Answer:
Step-by-step explanation:
Answer: x - 4y = 24
x + y = 4
Hope that helps
The system of equations is represented by these two tables is-
y = -x + 4
x - 4y = 24
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
Given are two tables as shown in the figure attached.
For table [1], we have -
m = (6 - 4)/(- 2 - 0)
m = 2/-2
m = -1
Equation -
y = -x + 4
For table [2], we have -
m = (-8 + 7)/(-8 + 4)
m = -1/-4
m = 1/4
Equation -
y = x/4 - 6
y = (x - 24)/4
4y = x - 24
x - 4y = 24
Therefore, the system of equations is represented by these two tables is-
y = -x + 4
x - 4y = 24

Which equation shows the correct factors for the quadratic equation 24x^2−15=54x?
Step-by-step explanation:
24x^2_54x_15=0
(12X +3 ) ( 2X _5 ) . = O
12x +3 =0
X= - 1/4
or
2x _ 5=0
X = 5/ 2
The equation that shows the factor for the quadratic equation is [tex](12x +3)(2x - 5) = 0[/tex]
The equation is given as:
[tex]24x^2 - 15 = 54x[/tex]
Equate to 0
[tex]24x^2 - 15 - 54x = 0[/tex]
Rewrite as:
[tex]24x^2 - 54x - 15 = 0[/tex]
Expand the above equation
[tex]24x^2 -60x + 6x - 15 = 0[/tex]
Factorize the above equation
[tex]12x(2x -5) + 3(2x - 5) = 0[/tex]
Factor out 2x - 5
[tex](12x +3)(2x - 5) = 0[/tex]
Hence, the equation that shows the factor for the quadratic equation is [tex](12x +3)(2x - 5) = 0[/tex]

if alpha and beta are the roots of the equation 2 x square - 7 x - 3 is equal to 0 find alpha + beta
Answer:
Values for alpha and beta are 0.5 and 3.
Step-by-step explanation:
2x² - 7x - 3 = 0
2x² - 7x - 3 = (2x - 1 )(x - 3)
∴ (2x - 1 )(x - 3) = 0
The only way to get zero by multiplying two values together, is if one of those values is qual to zero. Therefore, either (2x - 1 )=0, or (x - 3)=0.
If (2x - 1 )=0
∴2x=1
∴x=0.5
If (x - 3)=0
∴x=3
We have two values for x. These values represent alpha and beta.
(BTW - I'm not sure from the phrasing of your question whether or not you just want to find the values or whether you want to find the sum of the values (I don't know if you used '+' to mean 'and' or 'plus'), but if you do want to find the sum, it's of course just 0.5+3= 3.5.)
the hard-cover edition of a book cost 3 times as much as the paperback edition. Both editions together cost $26.60. Find the cost of each
Answer:

On a flight from New York to Nashville, an airplane travels at a constant speed of 500 miles per hour. The plane leaves at 3:30 PM and the distance between New York and Nashville is about 800 miles. At what time would you expect the plane to land? Be sure to include AM or PM in your answer.
Answer:
5:06PM
Step-by-step explanation:
t = [tex]\frac{1}{500}[/tex] d
t = [tex]\frac{1}{500}[/tex] × 800
t = [tex]\frac{800}{500}[/tex]
t = 1.6 hours
1 hr = 60 mins.
0.6 hours = 0.6 × 60 = 36 minutes
3:30PM + 1hr = 4:30PM
4:30PM + 36 mins. = 4:66 PM
4:66PM = 5:06PM
Dana buys a plant that is 4 inches tall. After one week the plant is 7 inches tall. After a second week the plant is 10 inches tall. At this rate, how tall will the plant be after the fifth week?
Answer:
19 inches
Step-by-step explanation:
The rate is 3 inches per week. 4+3=7 and 7+3=10. To find the height for the fifth week, all you need to do is add 3 inches every week...
Week 3: 10+3=13
Week 4: 13+3=16

Find the common difference of the arithmetic sequence, the next three terms, the equation, and the term given for 8, 10, 12, 14
Answer:
see explanation
Step-by-step explanation:
In an arithmetic sequence the common difference d is
d = a₂ - a₁ = 10 - 8 = 2
To obtain the next term in the sequence add d to the previous term, that is
a₅ = 14 + 2 = 16
a₆ = 16 + 2 = 18
a₇ = 18 + 2 = 20
The next 3 terms in the sequence are 16, 18, 20
The n th term equation for an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 8 and d = 2, thus
[tex]a_{n}[/tex] = 8 + 2(n - 1) = 8 + 2n - 2 = 2n + 6

Answer:
The answer is [tex]y=\frac{1}{6} x[/tex].
Step-by-step explanation:
According to the table, when you insert 6, it should give 1 as the area covered. The equation can be found by the slope formula, the change in y over the change in x. Which is in one increase in y, leads to 6 increase in x.
In that case, the equation holds. The same thing, when you put 12 to x. Gives you 2 as the area covered.

Choice 3, a = 1, b = 4, c = 5
Step-by-step explanation:
9/11 ÷ 5/11 = 9/5 (the denominators cancel)
Now take take the difference between the denominator and the numerator which is 9-5 which is 4.
5 goes into 9 once so a is 1, 4 which we solved as the difference is b, and c is the common denominator which is 5.
We are dividing the two fractions which make an improper fraction (fraction with a numerator greater than or equal to the denominator; making it greater than or equal to 1), and converting it to a mixed fraction which is a combination of a proper fraction, and whole number. So we get the mixed fraction 1 4/5 = 9/5

Simplify (x^2 -25)/ (2x^2-7x-15)
Answer:
[tex]\frac{x+5}{2x+3}[/tex]
Step-by-step explanation:
The simplified equation is [tex]\frac{(x + 5)}{ (2x + 3)}[/tex].
What is simplification?To simplify means to make anything easier. In mathematics, simplifying an equation, fraction, or problem means taking it and making it simpler. Calculations and problem-solving techniques simplify the issue. By eliminating all common factors from the numerator and denominator and putting the fraction in its simplest/lowest form, we can simplify fractions.
Given equation
[tex]\frac{x^{2} - 25}{2x^{2} - 7x - 15}[/tex]
take numerator
x² - 25 = x² - 5²
a² - b² = (a - b)(a + b)
x² - 5² = (x - 5)(x + 5)
for denominator
2x² - 7x - 15
factors of 2x² - 7x - 15 are
2x² - 10x + 3x - 15
2x(x - 5) + 3(x - 5)
2x² - 7x - 15 = (x - 5)(2x + 3)
the equation is [tex]\frac{(x - 5)(x + 5)}{ (x - 5)(2x + 3)}[/tex]
[tex]\frac{(x + 5)}{ (2x + 3)}[/tex]
Hence the simplified equation is [tex]\frac{(x + 5)}{ (2x + 3)}[/tex].
