Answer:
the answer is x<-9/2
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
When finding the least common denominator you look at the denominator of the fraction which is the number below the line.
To find the least common denominator in this question you would find the common multiple of 4,5,and 3
Which ever common multiple shows up first is your answer
Multiples of 4,5, and 3 :
4 8 12 16 20 24 28 32 36 40 44 48 52 56 60
5 10 15 20 25 30 35 40 45 50 55 60 65
3 6 9 12 15 18 21 24 27 30 33 36 39 42 45 48 51 54 57 60
The answer to this problem would be 60
Hey there!
7 + 5(3) - ( 6 - 2) ÷ 2
Let's do PEMDAS to solve this equation!
First step:
parentheses → 6 - 2 = 4, right?
Your problem becomes: 7 + 5 (3) - 4
The next step usually would be "e" for the exponents but since we don't have any, we have to move onto
Multiplication 5(3) = 15, right?
We have
division but we can save that for the last ( you don't have to do this method to solve this equation, by the way!)
Problem becomes: 7 + 15 - 4
Next, we do
addition
7 + 15 = 22, right?
Your problem becomes: 22 - 4
Next we do
subtraction
22 - 4 = 18, right?
Now we can do
division
Good luck on your assignment and enjoy your day!

What sample size is needed so that the length of the interval is $60 with 95% confidence? We Assume: σ = $150.
Showing Work:
n ======> is the sample size we want to find:
N = ( z a/2^σ / E )^2
= ( 1.96 * 150 / 30 )^2 (margin of error is 1.96 times the standard error):
Answer: =======> 96.04 ≈ 97
Hope that helps!!!! : )
0.0175, 0.65, 0.876
The smallest among these is 0.0175
after the decimal point, we see that in 0.0175 the tenth value is 0
in 0.65 the tenth value is 6
and in 0.876 the tenth value is 8
So from smallest to biggest(if needed)
0.0175, 0.65, 0.876
