Answer:
see below
Step-by-step explanation:
3( 4x - 3) + 8 = 2x + 10x -1
Distribute
12x - 9 +8 = 2x+10x -1
Combine like terms
12x - 1 = 12x - 1
Subtract 12x from each side
12x - 1 -12x = 12x - 1-12x
-1 = -1
This is true for all values of x
x = all real numbers
Answer:
All real numbers are solutions.
Step-by-step explanation:
3 ( 4x - 3 ) +8 = 2x + 10x - 1 Example 1:
12x - 9 + 8 = 12x - 1 3 ((4*1) -3) + 8 = (2*1) + (10*1) - 1
- 12x = -12x 3 ((4) - 3) + 8 = (2) + (10) - 1
-9 + 8 = -1 ( 12 - 9 ) + 8 = 12 - 1
-1 = -1 3 + 8 = 12 - 1
Example 2 11 = 11
3 ((4*6) - 3) + 8 = (2*6) + (10*6) - 1
3 ((24) - 3) + 8 = (12) + (60) - 1
72 - 9 + 8 = 72 - 1
72 - 1 = 72 - 1
71 = 71
What is the product of the binomials
Answer:
(x-9)(x+2) = x^2 + 2x -9x -18 = x^2 -7x -18

can someone help me with this I do not understand it?
Answer:
So, the first one is not proportional and therefore has no multiplier.
You are right on the second on both counts!
Step-by-step explanation:
You just need to divide the x's by the y's (individually) in order to determine what they are multiplied by. And the answers you get for the first one will be 5, 6, and 7. Because the numbers are different, they are not proportional.

You and two of your friends go to eat pizza together. There are two deals: 10% off of 1 pizza 30% off of 3 pizzas Do you want to each pay separately and get 10% off of your bill or do you want to split the bill 3 ways and get 30% off of 3 pizzas? Write a paragraph that convinces your teacher which one is the better deal. Show all of the math involved in your calculations.
Please help :(
Answer:
The first one is the better deal.
Step-by-step explanation:
The first one is the better deal =====
30% of 3 = 0.9
0.9 = 90
10% of 1 = 0.1
0.1 = 10
So the better deal would be 10% of 1

A proton is a very tiny particle inside an atom. The mass of a proton is
estimated to be 0.00000000000000000000000167 g. What is the mass of a proton in scientific notation?
Answer:
1.67x10-24
Step-by-step explanation:
The mass of the proton in scientific notation is given by:
[tex]1.67 \times 10^{-24}[/tex]
A number in scientific notation has the following format:
[tex]y = a \times 10^b[/tex]
a is a number in the interval [tex][1, 10)[/tex].b is the power of 10. If the number is greater than 1, the power is positive. If the number is between 0 and 1, the power is negative.In this problem, the number is: [tex]0.00000000000000000000000167[/tex].
To place into scientific notation, we need that [tex]a = 1.67[/tex].Moving the decimal point to after the 1, it would move 24 places, in a number between 0 and 1, thus [tex]b = -24[/tex]Thus, the mass of the proton, in scientific notation, is of:
[tex]1.67 \times 10^{-24}[/tex]

barn help me please
48π cm^3
Step-by-step explanation:
The formula for the volume of a cone is...
[tex]V=\frac{1}{3}\pi r^2h[/tex]
We can plug everything we know from the photo into the equation, but note that the picture gives us the diameter, which is 8, instead of the radius. The radius is half of the diameter, so the radius will be 4. Also we will be leaving pi as it is, instead of changing it to 3.14.
[tex]V=\frac{1}{3}*(\pi *4*4*9)[/tex]
[tex]V=\frac{1}{3}*(144\pi )[/tex]
V = 48π
The paper cone can hold 48π cubic centimeters of water.
Answer:
Step-by-step explanation:
d = 8 cm
r =8/2 = 4 cm
h = 9cm
Volume of cone = (1/3)πr²h
[tex]=\frac{1}{3}\pi *4*4*9\\[/tex]
= 4*4*3*π
= 48π cubic centimeteres
The edge length of a cube-shaped crate is the square of the edge length of a cube-shaped box. Write an expression for the number of boxes that can fit in the crate.
Answer:
[tex]s^3[/tex]
where s is the edge length of the cube-shaped box
Step-by-step explanation:
Let the edge length of the cube-shaped box=s
The edge length of a cube-shaped crate is the square of the edge length of a cube-shaped box.
Therefore, edge length of the cube-shaped crate[tex]=s^2[/tex]To determine the number of boxes that can fit in the crate, we first find the volume of the crate and the box.
Volume of the cube-shaped crate of side length [tex]s^2=(s^2)^3=s^6 $ cubic units[/tex]Volume of the cube-shaped box of side length [tex]s=s^3 $ cubic units[/tex]Therefore, the number of boxes that can fit in the crate
=Volume of Crate divided by Volume of Box
[tex]=\frac{s^6}{s^3}\\=s^{6-3}\\=s^3$ boxes[/tex]
Therefore, an expression for the number of boxes that can fit in the crate is [tex]s^3[/tex].

How do you solve 84.48 ÷ 0.88? Please explain it step-by-step!
Answer:
96
Step-by-step explanation:
Answer: 96
Step-by-step explanation:
84.48/0.88
The first step to dividing decimal numbers is to convert them into whole numbers. You can do this by multiplying 1 followed by as many zeros as decimal numbers there are. In this case, we have 2 decimal numbers, therefore, we must multiply by 1 followed by 2 zeros rather 100.
