Answer:
-8/3
Step-by-step explanation:
2 - x = - 6 - 4x <-- Add 4x to the left side
2 + 3x = - 6 <-- Subtract 2 from the left side
3x = -8 <-- Divide 3 on both sides
x = -8/3
Answer:
x = -8/3
Step-by-step explanation:
Consolidate x terms on the right side:
2-x= -6-4x becomes 2-x + x = -6-4x + x, which in turn becomes:
2 = -6 - 3x, or 3x = -8. Then, dividing both sides by 3, we get x = -8/3
The total bill for drinks and a pizza for three people is $14.90 before tax. The group wants to leave a 15% tip on the cost of the food, not including tax. What will be the amount of the tip?
Answer:
$2.24
Step-by-step explanation:
Since we are trying to find a percentage of something, we can multiply whatever we're trying to find a percentage from by 0.X where X is equal to the number of the percentage. So in this case it's 15%. We can multiply $14.90 by 0.15 and we get 2.23500. Since we cannot have 2.235 dollars, we must round up decimal places.
The tip would be 2 dollars and 24 cents. ($2.24).
Write the series using summation notation.
-2 +4-8 + 16 - 32
Answer:
Σ (-2)^n
n=1

Mary is buying a case of water. She spends $7.99 for a case of 24 bottles. What is the unit rate? (Cost for 1 bottle) *
Answer:
so I'm not 100% sure but in these types of questions you are supposed to divide
so you have a pack of 24 bottles for 7.99
so you would do 7.99÷24 = 0.33
then to check it you can multiply
0.33× 24 bottles and it gives you 7.93 which is super close to 7.99 anyway I hope this helps ...

Step-by-step explanation:
The function table below represents the linear function y = 4x – 3. Which answer represents the outputs of the function table
Answer:
Here we can not see the options, so i will answer in a general way.
When we have a function y = f(x), we define:
x as the input
y as the output.
so f(x) is some kind of "machine", in wich we put an input x, and the "machine" does something and returns an output y.
In, this case, we have:
y = f(x) = 4*x - 3
then if we give this function different inputs, we will get different ouputs.
for example, if we use the input x = 0, then the output is:
y = f(0) = 4*0 - 3 = -3
Then if we made a table for inputs and outputs, we will have the data:
[tex]\left[\begin{array}{ccc}inp&out\\x&y\\0&-3\end{array}\right][/tex]
We can rewrite this table in a general way as:
[tex]\left[\begin{array}{ccc}inp&out\\x&4*x - 3\end{array}\right][/tex]
This means that for every input x, the output is always 4*x - 3.
To complete this type of tables, we usually use different values of x, for example here I will use some different ones:
y = f(3) = 4*3 - 3 = 12 - 3 = 9
y = f(10) = 4*10 - 3 = 40 - 3 = 37
y = f(-1) = 4*-1 - 3 = -4 - 3 = -7
Then we will have a table like:
[tex]\left[\begin{array}{ccc}inp&out\\3&9\\10&37\\-1&-7\end{array}\right][/tex]
Concluding, the thing that will always represent the output of our function is: 4*x - 3.

Which value is MEAN of the data set?
A)
480
B)
485
500
D)
The MEAN cannot be determined from the available information.
Answer:
500
Step-by-step explanation:
I believe the answer is D) The mean cannot be determined from the available information.
The mean in math means the sum of all the numbers divided by how many numbers there are. There is no information about how many numbers there are nor any information of which numbers exist and which numbers don't.
The data set only tells us the first number, last number, and median-- things a box-and-whisker plot would tell us; perhaps a different way of representing data would work better to help us find the median like a dot plot or a bar graph.
If this is incorrect, please, don't refrain to tell me. Thank you.

The bill for car repairs is $425 for parts and labor. The cost of parts is $226 and labor is $36.00 per hour. If h represents the number of hours of labor, which equation can you use to find the number of hours of labor?
Group of answer choices
226 = 425 – 36h
226(h + 226) = 425
36 + 226h = 425
36h + 226 = 425
Answer:
the third one
Step-by-step explanation:
36+ 226h=425, I hope this helps:)

Help me ? Pleaseeeee ??!!!
Answer:
57
Step-by-step explanation:
if 1 = 123 degrees, and the angles add up to 360, then 6 would be 57. Because you would do 123 is 5 and 8, and so 246 is adding those angles. So now you have 7 and 6. 360 - 246 is 114, and since 7 and 6 are equal, just divide that by 2
Name the marked angle in 2 different ways.
Answer:
acute is one of the i hope this helps

Find the range of values for which
x2 - 6x + 8 < 0
Answer:
Step-by-step explanation:
Factor
x^2-6x+8<0
(x-2)(x-4)<0
For this to be less than zero the factors must have opposite signs.
x>2 and x<4
2<x<4
So x is all real numbers between 2 and 4 or in interval notation
x=(2,4)
