solve for X, will give you brainliest and a like
Answer
Step-by-step explanation:
One solution :
x = -1/3 = -0.333
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-5*(3*x+1)+4*x-(10*x+2)=0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
((0 - 5 • (3x + 1)) + 4x) - (10x + 2) = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
-21x - 7 = -7 • (3x + 1)
Equation at the end of step 3 :
-7 • (3x + 1) = 0
Step 4 :
Equations which are never true :
4.1 Solve : -7 = 0
An in-ground swimming pool is meters long, meters wide, and meters deep. The water-resistant paint needed for the pool costs $ per square meter. Step by step.
1. How many sides of the pool do you have to paint?
2. How much paint (in square meters) do you need to paint the pool?
3. How much will it cost to paint the pool?
4. How much water will the pool hold?
Answer:
Step-by-step explanation:
I'm going to assume you meant to put numbers in the question, but I will answer in terms of x, y, and z, for length, width, and depth, respectively.
1. You need to pain 4 walls as well as the floor, so 5 surfaces total.
2. This question is asking for the surface area of the pool. There is 1 floor, 2 long walls and 2 wide walls.
Surface Area = 2 (wide) + 2 (long) + 1 (floor)
= 2(x*z) + 2(y*z) + 1(x*y)
*remember to answer in meters squared*
3. Total Cost = (surface area) * (cost per square meter)
*remember this is in dollars*
4. This question is asking about the volume of the pool:
Volume = x*y*z
What’s the answer???
And please explain
Answer:
35 square units
Step-by-step explanation:
[tex]area \: of \: { \parallel}^{gm} = b \times h \\ = 7 \times 5 \\ = 35 \: {units}^{2} [/tex]

What is the twentieth term of the arithmetic sequence described by the
equation an= 3n - 10?
Answer:
The twentieth term is 50.
Step-by-step explanation:
The equation that describes the arithmetic sequence describes it's "general term", which means that all the numbers in that sequence must follow that equation. For instance, if we want to find the first term of the sequence we must make a = 1 and we have:
a1 = 3*1 - 10
a1 = -7
Therefore to find the twentieth term we need to make n equal to 20. This is done below:
a20 = 3*20 - 10
a20 = 60 - 10
a20 = 50
The twentieth term is 50.
DVD players are going out of fashion in the modern era. If 400,000 DVD players were sold this year and sales are declining at a rate of 31% per year, how many will be sold 3 years from now?
130,000
131,404
128,000
399,876
Answer:
c
Step-by-step explanation:
Answer:
399,876
Step-by-step explanation:
So, 400,000 DVD sales with a 31% decline means in the first year following, there will be a decline of 124,000 DVDs sold. So we need to take 400,000-124,000 which equals a starting point for your two is 276,000 dvds. Then, add 123,876, which gives you 399,876.

Answer:
1/9
Step-by-step explanation:
3/9 of original recipe
3/9=1/3 (on simplifing) Is the recipe we want to make
so 1/3 of the recipe we want to make
=(1/3) * (1/3)
=1/9

18/100 = .18
58 x .18 = 10.44
58 + 10.44 = 68.44
:)
Answer:
It would be 68.44
Step-by-step explanation:
What you do is you multiply 58 by .18. it should come out to 10.44. Once you do that, you add the $58 dollar check with the 10.44 tip and the answer is 68.44!!

Calculate the volume of the figure. Use 3.14 for π.
Enter your answer as the number of m3, rounded to the nearest hundredth if necessary, like this: 42.53
Answer:
[tex]586.13\,\,m^3[/tex]
Step-by-step explanation:
Given: Figure
To find: Volume of the figure
Solution:
The given figure is composed of two shapes:cylinder and hemisphere
Radius of cylinder = 4 m
Height of cylinder = 9 m
Volume of cylinder = [tex]\pi (radius)^2height=\pi (4)^2(9)=3.14(16)(9)=452.16\,\,m^3[/tex]
Volume of hemisphere = [tex]\frac{2}{3}\pi (radius)^3=\frac{2}{3}(3.14)(4)^3= \frac{2}{3}(3.14)(64)=133.9733\,\,m^3[/tex]
So,
total volume of the figure = Volume of cylinder + Volume of hemisphere = 452.16 + 133.97 =586.1333 [tex]m^3[/tex]
If 586.1333 is rounded to the nearest hundredth, it becomes 586.13 [tex]m^3[/tex]
Answer:
586.13 is the answer

Which of the following are factors of the
polynomial?
Answer:
All of the above
Step-by-step explanation:
In mathematics, a polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. Since, they all have a degree of 1 they are all polynomials.
Which of the following equations is never true?
A. a^2 = -25
B. x^2 = 16
C. y + 4 = 10
D. 2x = 7
Answer: A. a² = -25
Step-by-step explanation:
The square of a number can never be negative and as such a² ≠ - 25.
Proof of this is that the √-25 = 5i (aka an imaginary number).

Find the volume of a rectangular pyramid. Length measures 16 meters, width measures 24 meters, height measures 20 meters
Answer:
7680
Step-by-step explanation:
16(24)20

V = 2,560 m^3
Step-by-step explanation:
The formula for the volume of a pyramid is...
[tex]V=\frac{1}{3}Bh[/tex]
B is the area of the base, which in this case is a rectangle. We need to find the area of the rectangle to plug in for B.
The formula for the area of a rectangle is...
[tex]l*w[/tex]
We can plug in the numbers.
[tex]16*24[/tex]
= 384
Now that we have B, we can plug that into the volume formula along with the height.
[tex]V=\frac{1}{3}(384*20)[/tex]
[tex]V=\frac{1}{3}*7,680[/tex]
V = 2,560 m^3
