Answer:
Eric's share is $1,800.
Step-by-step explanation:
You can write the following equations from the information given:
x+y+z=2,700 (1)
y=2z (2)
x=3y (3), where:
x=Eric's share
y= Jo's share
z=Richard's share
Now, you can replace (2) in (1) and (3) to have two equations:
x+2z+z=2,700
x+3z=2,700
x=3(2z)
x=6z
The two equations are:
x=6z (4)
x+3z=2,700 (5)
Then, you can replace (4) in (5) and solve for z:
6z+3z=2,700
9z=2,700
z=2,700/9
z=300
After this, you can replace the value of z in (4) to find x:
x=6*300
x=1800
Finally, you can replace the value of z in (2) to find the value of y:
y=2*300
y=600
According to this, the answer is that Eric's share is $1,800.

Answer:
0.3 and
Step-by-step explanation:
You can convert the fraction to a decimal by dividing the numerator by the denominator.
Dividing 1 and 3 would get me 0.3.
Same goes for 2/3. If I divide 2 and 3, it would get me 0.6.

Hey there!
[tex]Answer:\boxed{x=6}[/tex]
[tex]Explanation:[/tex]

Let's start with subtracting 0.2 from both sides of the equation.
[tex]8x+0.2-0.2=48.2-0.2\\8x=48[/tex]
In our second/last step, we will divide both sides by 8.

Answer:
1. (10, -⁸/₃)
2. (2, ⁸/₃)
3. (12, -4)
Step-by-step explanation:
I will do the first 3 as examples.
1. Y is ⅔ of the distance from X to Z.
Y − X = ⅔ (Z − X)
The x-coordinate of Y is:
x − -6 = ⅔ (18 − -6)
x + 6 = ⅔ (24)
x + 6 = 16
x = 10
The y-coordinate of Y is:
y − 8 = ⅔ (-8 − 8)
y − 8 = ⅔ (-16)
y − 8 = -³²/₃
y = -⁸/₃
Y is at (10, -⁸/₃).
2. The ratio of XY to YZ is 1:2.
(Y − X) / (Z − Y) = 1 / 2
Cross multiply.
2 (Y − X) = Z − Y
The x-coordinate of Y is:
2 (x − -6) = 18 − x
2x + 12 = 18 − x
3x = 6
x = 2
The y-coordinate of Y is:
2 (y − 8) = -8 − y
2y − 16 = -8 − y
3y = 8
y = ⁸/₃
Y is at (2, ⁸/₃).
3. Y is ¼ of the distance from Z to X.
Y − Z = ¼ (X − Z)
The x-coordinate of Y is:
x − 18 = ¼ (-6 − 18)
x − 18 = ¼ (-24)
x − 18 = -6
x = 12
The y-coordinate of Y is:
y − -8 = ¼ (8 − -8)
y + 8 = ¼ (16)
y + 8 = 4
y = -4
Y is at (12, -4).

Marianne wanted to know students' opinion on the new schedule at school. She survey's the first
30 students who come into her class. What type of sampling is this?
I think it is a Convience Sampling.
The type of sampling that Marianne is using is convenience sampling.
What is convenience sampling?Convenience sampling is a non-probability sampling method where individuals are selected based on their availability and willingness to participate in the study.
Here, Marianne surveyed the first 30 students who came into her class, which means that she selected the participants based on their convenience of being there at that particular time.
Convenience sampling is not a random sampling method, and it can introduce bias into the results because the sample may not be representative of the population of interest.
In this case, the sample of students may not represent the entire student population at the school, and the results may not be generalizable to other students.
Thus, the type of sampling that Marianne is using is convenience sampling.

6(2t+9)<12t-1 what is the answer
Answer:
no solutions
Step-by-step explanation:
The inequality: 6(2t+9)<12t-1
First, use distributive property
12t+54<12t-1
Now, add 1 on both sides
12t+55<12t
Subtract 12t on both sides
55<0
This is incorrect, so there are no solutions.
Determine whether the triangle with vertices at the points below is scalene, isosceles, or equilateral:
(3, 4), (8, -1), (10,3)
Answer:
Step-by-step explanation:
This is a isosceles triangle, An isosceles triangle is a triangle with (at least) two equal sides. In the figure above, the two equal sides have length and the remaining side has length.
A scalene triangle is a triangle in which all three sides have different lengths. Also the angles of a scalene triangle have different measures.
In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.

The factored form of equation is 9t²(3t-4) - 4(3t+4)
What is factored form of an equation?
A factored form is a parenthesized algebraic expression. In effect a factored form is a product of sums of products … or a sum of products of sums … Any logic function can be represented by a factored form, and any factored form is a representation of some logic function.
According to the question
The factored form of equation :
[tex]27t^3 - 36t^2 - 12t - 16[/tex]
taking common from first two terms and last two terms
9t²(3t-4) - 4(3t+4)

Answer:
Step-by-step explanation:
what is the solution to this inequality: -4(3x-5)<2(3x+4)
Answer:
x > 2/3
Step-by-step explanation:
-4(3x - 5) < 2(3x + 4)
Divide both sides by 2.
-2(3x - 5) < 3x + 4
Distribute on the left side.
-6x + 10 < 3x + 4
Subtract 3x from both sides.
-9x + 10 < 4
Subtract 10 from both sides.
-9x < - 6
Divide both sides by -9. Remember that when you divide both sides of an inequality by a negative number, the inequality sign changes direction.
x > (-6)/(-9)
x > 6/9
x > 2/3
