Answer:
3*( 8-2n)=5n
The number is 24/11
Step-by-step explanation:
three times
3*
the difference of eight and twice a number
3*( 8-2n)
is five times the number
3*( 8-2n)=5n
To solve
Distribute
3*8 -3*2n = 5n
24 -6n = 5n
Add 6n to each side
24 - 6n +6n = 5n +6n
24 = 11n
Divide each side by 11
24/11 = 11n/11
24/11 =n
The number is 24/11
<span>-29= 5 (2a-1) +2a
Start by distributing the terms....
- 29 = 10a - 5 + 2a
Combine like terms...
- 29 = 12a - 5
Add 5 to both sides ....
- 2 4 = 12 a
Divide both sides by 12 to get a by its self...
a = -2

Answer:
x=60,150,240,330
Step-by-step explanation:
Take the arc cot of both sides
Remember cotangent has a period of 180 degrees
where n is 0, 1,2,3,4,5.....
Isolate x.
where n is 0, 1,2,3,4,5,6.
Keep plugging in integers as long they are in the interval [0,360].
We get
60,150,240,330.
The conclusion drawn from the study is instance because the sample is homogenous and an experimental study was performed.
<h3>What is an experimental study?</h3>
An experimental study deals with a dependent variable and there is a dependent variable.
Also, a control is used to establish the validity of the results.
The dependent variable is the level of softness after treatment while the independent variable is the type of water softener used.
