Wich equation has a solution of 2/3 for n?
Answers
Answer:
[tex]15n=10\\\\n=\dfrac{10}{15}\\\\n=\dfrac{2}{3}[/tex]
Step-by-step explanation:
We need to find out of 4 options which equation has a solution of 2/3 for n.
Equation (1).
[tex]n-1=\dfrac{1}{3}\\\\n=\dfrac{1}{3}+1\\\\n=\dfrac{4}{3}[/tex]
Equation (2).
[tex]16n=24\\\\n=\dfrac{24}{16}\\\\n=\dfrac{3}{2}[/tex]
Equation (3).
[tex]15n=10\\\\n=\dfrac{10}{15}\\\\n=\dfrac{2}{3}[/tex]
Equation (4).
[tex]1\dfrac{1}{3}+n=3\\\\n=3-\dfrac{4}{3}\\\\n=\dfrac{5}{3}[/tex]
So, equation (3) has a value of n as 2/3. Hence, the correct option is (3).

Nori had 2 1/12 bags of apples. He used 1 5/12 bags of apples to make pies How many bags of apples does Nori has left
Answers
Answer:
3 1/2
Step-by-step explanation:
Answer is 8/12.
Mixed number Fraction:
A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.
(Here),
Nori had [tex]2\frac{1}{12}[/tex] bags of apples.
Given, he used [tex]1\frac{5}{12}[/tex] bags of apples.
Nori left = [tex]2\frac{1}{12}[/tex] - [tex]1\frac{5}{12}[/tex]
=> (25 / 12) - (17 / 12)
=> 8 / 12 => (2 / 3)

A line passes through point A(12,18). A second point on the line has an x-value that is 125% of the x-value of point A and a y-value that is 75% of the y-value of point A. Use point A to write an equation of the line in point-slope form.
PLEASE! PUT THIS IN POINT SLOPE FORM!
Answers
Answer:
y - 18 = -1.5(x - 12)
Step-by-step explanation:
A = (12, 18)
B=(1.25(12), 0.75(18)) = (15, 13.5)
Find slope: m = (13.5-18)/(15-12) = (-4.5)/3 = -1.5
Point slope form: y - y1 = m(x - x1)
Using point A as (x1, y1)
y - 18 = -1.5(x - 12)

QRST is a rectangle. If RT = 4x - 16 and SQ = x + 5, find the value of x.
Answers
Answer:
The value of x is 7.
Step-by-step explanation:
Both RT and SQ are diagonals of the rectangle, so they have the same measure.
We have that:
[tex]RT = 4x - 16, SQ = x + 5[/tex]
Since they are equal:
[tex]4x - 16 = x + 5[/tex]
[tex]4x - x = 5 + 16[/tex]
[tex]3x = 21[/tex]
[tex]x = \frac{21}{3}[/tex]
[tex]x = 7[/tex]
The value of x is 7.

What word describes the slopes of the line
Answers
Answer:
Positive
Step-by-step explanation:
There are a couple ways we can go about this.
First, we can see that as x increases, so does y, so that means its positive
For perspective, if x is the amount of time and y is the number of sales, we can see that the sales are going up and not going down or staying at the same place
If you wanna check your work on that, you can plot two points and find the slope using y1-y1/x1-x2 and the slope will be positive.
We can also use the process of elimination, we know it can't be zero because it's not a straight, horizontal line and we know its not undefined because it isn't a straight vertical line, so it's between negative and positive, and since the line is going up, that means that it's positive.

An equation for a vertical line that contains E(-7,-1)
Answers
Answer:
The equation of the line containing the point (-7, -1) will be:
x = -7The graph of the vertical line containing the point (-7, -1) is also attached below.
Step-by-step explanation:
Given the point
E(-7, -1)It means:
at x = -7, the value of y = -1.
Given that the line is vertical. It means no matter what the value of y is, the value of x remains the same.
In other words, the value x does not change for any value of y.
Therefore, the equation of the line containing the point (-7, -1) will be:
x = -7The graph of the vertical line containing the point (-7, -1) is also attached below.

Find the cost of 1 slice for Cheese A:
Set up a proportion: [tex]\frac{3.59}{10} = \frac{x}{1}[/tex] Cross multiply, then divide: 3.59 × 1 = 3.59, 3.59 ÷ 10 = 0.359So, the cost of 1 slice of Cheese A is $0.359Find the cost of 1 slice for Cheese B:
Set up a proportion: [tex]\frac{5.12}{16} = \frac{x}{1}[/tex] Cross multiply then divide: 5.12 × 1 = 5.12, 5.12 ÷ 16 = 0.32So, the cost of 1 slice of Cheese B is $0.32Make a conclusion:
Because $0.32 is less than $0.359, Cheese B is the better buy.

Key Skills are: Factoring, GCF, and Simplifying
We have the expression 6[tex]m^{2}[/tex] + 8mp.
1) We want to find the greatest factor among both terms (1 of the terms is 6m^2 and the other is 8mp).
2) Both of these terms have a factor of m, and both are divisible by 2.
3) Therefore, you can take out 2m and get 2m(3m+4p)
