Answer:
60
Step-by-step explanation:
90x + 270= 5670
90x=5670-270
x=5400÷90
x=60
Answer:
x = 60
Step-by-step explanation:
1) 100x - 10x + 270 = 5670
2) 100(60) - 10(60) + 270 = 5670
3) 6000 - 600 + 270 = 5670
4) 5400 + 270 = 5670
5) 5670 = 5670
All I really did was input random numbers for the value of "x", then add 270 at the end of an equation. If that method works for me, it should work for everyone, including you.
Hope this helped buddy!

There are only red beads and green beads in a bag.
The ratio of the number of red beads to the number of green beads is 5:9
(a) What fraction of the beads are red?
Answer:
Assume there are 5x red beads and 9x green beads
Total no. of beads = 5x+9x = 14x
Fraction of beads that are red = 5x out of 14x
or 5/14

p/q=r/s (solve for q)
Answer:
q=pr/s
Step-by-step explanation:
p/q=r/s multiplication is the inverse of division so they cancel out. and you have to do the same thing to both sides so multiply both sides by "q" it cancels out on the left and stays on the right leaving you with
q=pr/s

Using the numbers 5, 8, and 24, create a problem using no more than four operations (addition, subtraction, multiplication, division, square, square root, cube, cube root) where the solution will be an irrational number.
Explain why the result of your operations is an irrational number.
somebody please help me :(
all i know is that this is the equation √(24x5-8)
I need help checking the answer to it.
I think it's 10.583005244
I'm not sure and i need all teh help i can get, thanks
Answer:
Take the square root of a number that is not a perfect square. None of the numbers are perfect squares. After you do that you can do any closed operation you want with the resulting irrational and the two other rationals and you will end up with an irrational.
8*24*√5 is an example.
8+24+√5 is another
5*√8 + 24 is another.
If you take the cube root of any number that isn't a perfect cube you get an irrational, so you could take the cube root of 5 or 24 instead of the square root and do the same thing.

1Convert the following equation to slope-intercept formy-3=\frac{1}{8}\left(x+8\right)y−3=8(x+8)
Answer:
y = 8x + 67
Step-by-step explanation:
The equation of a line in slop- intercept form is
y = mx + c
Given
y - 3 = 8(x + 8) ← distribute parenthesis
y - 3 = 8x + 64 ( add 3 to both sides )
y = 8x + 67 ← in slope- intercept form
4. Solve the following equation for q. 5q- 4q + 6 = 4q - 8.
q = 4p - 14
q = 4p + 14
q = 4p - 2
q = 4p + 2
Answer:
q=4p-14
Step-by-step explanation:
> 5q-4q+6=4q-8
> 5q-4q+6+8=4p
> q+14=4p
> q=4p-14

Let f(x)=x−2
Write a function g whose graph is a translation 3 units to the left of the graph of f.
Answer:
f(x) = (x + 3)
Step-by-step explanation:
when it's in the parentheses, it's the opposite so in this if it's saying 3 units to the left, it would be subtracting or negative so to make it the opposite u do x + 3 in parentheses

-1/3(9x-18)+8x simplified. Please awnser my question quick I need it!!
Answer:
5x-6
Step-by-step explanation:
Multiply 9x and 18 with -1/3
-1/3 times 9x is -3x
-1/3 times 18 is -6
So the equation looks like this:
-3x-6+8x
8x plus -3x is 5x
So the answer is: 5x-6

4. Create a set of 5 positive numbers (repeats allowed)
that have a median of 20 and a mean of 10. (or explain
why it can't be done)
Answer:
It cannot be done.
Step-by-step explanation:
Every single instance of a graph will always have a median of 20, because 20 is the only number that can go into 100 evenly 5 times.
