Solve −3(7n+3)<6n. Write the solution using set-builder notation.
The set builder notation of the inequality - 3(7n + 3) < 6n is,
{n : n ∈ R, n > - 3 }.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
Given, An inequality - 3(7n + 3) < 6n.
Now, distributing the terms we get,
- 21n - 9 < 6n.
- 21n - 6n < 9.
- 27n < 9.
27n > - 9. (Think of moving the variable to the other side to make it
positive).
n > - 27/9.

A = LW
L = 50
W = 15
Give your answer in simplest form.
Enter
Answer:
A = 750
Step-by-step explanation:
Start with what we know:
A = LW
L = 50
W = 15
Then we fill in the values we know into the equation to get our answer.
A = L, or 50, times W, or 15.
Our new equation is A = 50 × 15
And we solve to find our answer
A = 50 × 15 or A = 750
A gardening store ordered 657,230 potted plants last year. This year, the store ordered 10% fewer potted plants. How many potted plants were ordered this year?
Potted plants ordered last year = 6,57,230 (Indian Place Value System)
Pecentage of plants deducted = 10%
10% of 6,57,230 = 10/100 × 6,57,230
or, it can also be written as -
10/10 × 65,723
or,
65,723
Therefore, potted plants odered this year is 65,723
By the way, I'm an Indian : )

How many solutions in the equation 3x + 5 = 3x + 10 *
Answer:
Simplifying
3x + -5 = 3x + -10
Reorder the terms:
-5 + 3x = 3x + -10
Reorder the terms:
-5 + 3x = -10 + 3x
Add '-3x' to each side of the equation.
-5 + 3x + -3x = -10 + 3x + -3x
Combine like terms: 3x + -3x = 0
-5 + 0 = -10 + 3x + -3x
-5 = -10 + 3x + -3x
Combine like terms: 3x + -3x = 0
-5 = -10 + 0
-5 = -10
Solving
-5 = -10
Step-by-step explanation:
The solution is, solutions in the equation 3x + 5 = 3x + 10 is no solution.
What is simplification?Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.
here,, we have,
Simplifying
3x + -5 = 3x + -10
Reorder the terms:
-5 + 3x = 3x + -10
Reorder the terms:

Add '-3x' to each side of the equation.
-5 + 3x + -3x = -10 + 3x + -3x
Combine like terms: 3x + -3x = 0
-5 + 0 = -10 + 3x + -3x
-5 = -10 + 3x + -3x
Combine like terms: 3x + -3x = 0
-5 = -10 + 0
-5 = -10

Answer: A 128 square sm
Step-by-step explanation:
So the wedge consists of a square and a triangle. We need to find the area of both using 2 formulas:
A=1/2bh for triangle
A= l*w for square
Starting with the square 8*10=80 so the area of the square is 80 square cm
Now the triangle is 12*8/2 so = 48 square cm
So add the two to get 48+80= 128 Square centimeters which is choice A

g(x) = 8x + 2
f(x) * g(x) = (3x - 7)(8x + 2) {Use FOIL method}
= 3x*8x + 3x *2 +(-7)*8x + (-7)*2
= 24x² + 6x - 56x - 14 {Combine like terms}

What is the volume of a prism with a length of 3 units, a width of 6 units, and a height of 2 units?
Answer:
36 units³
Step-by-step explanation:
The volume of a rectangular prism is given by
Volume, V = l * w * h, where
V = volume like I had stated
L = length of the prism
w = width of the prism
h = height of the prism
Going by the aforelisted parameters, we can apply them to the formula to get our answer straight
Volume, V = 3 * 6 * 2
Volume, V = 36 units³
Therefore, the volume of the prism is 36 units³

Given:
The expression is:
[tex]-1(2x+3)-2(x-1)[/tex]
To find:
The simplified form of the given expression.
Solution:
We have,
[tex]-1(2x+3)-2(x-1)[/tex]
Using distributive property, we get
[tex]-1(2x+3)-2(x-1)=-1(2x)-1(3)-2(x)-2(-1)[/tex]
[tex]-1(2x+3)-2(x-1)=-2x-3-2x+2[/tex]
On combining like terms, we get
[tex]-1(2x+3)-2(x-1)=(-2x-2x)+(2-3)[/tex]
[tex]-1(2x+3)-2(x-1)=-4x-1[/tex]
Therefore, the simplified form of the given expression is [tex]-4x-1[/tex].
Note: The correct option is not available.

The mean temperature for the first 4 days in January was -4°C. The mean temperature for the first 5 days in January was -6°C. What was the temperature on the 5th day? Pls help
Answer:
-14°C
Step-by-step explanation:
Given that,
The mean temperature for the first 4 days in January was -4°C.
The mean temperature for the first 5 days in January was -6°C.
Mean = sum of observations/no. of observations
For first 4 days,
[tex]-4=\dfrac{S_4}{4}\\\\S_4=-16\ ...(1)[/tex]
For first 5 days,
[tex]-6=\dfrac{S_4+T}{5}\\\\S_4+T=-30\ ..(2)[/tex]
Let the temperature on 5th day is T. So,
Put S₄ = -16 in equation (2).
-16 + T = -30
T = -30+16
T = -14°C
So, the temperature on the 5th day is -14°C.
