The solution to the equation 1/3|x - 8| = 10 is x = 38
What are expressions?Expressions are mathematical statements that are represented by variables, coefficients and operators
How to determine the solution to the equation?The equation is given as
1/3|x - 8| = 10
Multiply through by 3
So, we have
|x - 8| = 30
Remove the absolute bracket
So, we have
x - 8 = 30
Add 8 to both sides of the equation
So, we have
x = 38
Hence, the solution to the equation is x = 38

Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form.
4,12,36
Answer:
Step-by-step explanation:
this is clearly not a linear sequence (the terms don't have the same difference).
so, it has to be a geometric sequence.
the common ratio is r.
s2 = s1 × r
16 = 64 × r
r = 16/64 = 1/4
control :
s3 = s2×r
4 = 16 × 1/4 = 4
correct.

Answer:
Ranked least to greatest:
l 125 l
l -127 l
l -132 l
(the absolute value of 125, the absolute value of -127, and the absolute value of -132)
Step-by-step explanation:
Absolute value are the bars around a number that essentially is the distance of that number from ZERO. An easy way to visualize this is through a numberline. Therefore, even negative numbers under the absolute value of, become positive since the distance from zero can't be negative.
Looking at the problem, descending means going down in this case it symbolizes the negative.
So putting absolute value bars around each number we know that the absolute value of 125 is 125.. The absolute value of -132 is 132. The absolute value of -127 is 127.
Ordered from least to greatest we get: 125, 127, 132.

FInd the equation of the line that passes through (1,3) and is perpendicular to y=1-2x. Leave your answer in the form ax+by=c Where a,b and c are integers.
Answer:
[tex]y = \frac{x}2 + 2.5[/tex]
Step-by-step explanation:
Step 1) Finding the slope
The line is perpendicular to [tex]y = 1 - 2x[/tex], therefore, its slope is equal to the negative invert of [tex]y[/tex]'s slope.
[tex]y[/tex]'s slope is -2 (the coefficient to [tex]x[/tex]), and, therefore, the line's slope is [tex]m = [-(-2)]^{-1} = 2^{-1} = \frac12[/tex]
Step 2) Building the Equation
We can now substitute the slope, along with the given point's coordinates, into the formula [tex]y - y_1 = m(x - x_1)[/tex] :
[tex]y - 3 = \frac12(x - 1)\\\to y - 3 = \frac{x}2 - \frac12\\\to y = \frac{x}2 + 2.5[/tex]

what is the interest of rs 2500 for 5 years at the rate of 2 paisa per 2 months of rs 2?
Answer:
First, converting R percent to r a decimal
r = R/100 = 3.875%/100 = 0.03875 per year,
then, solving our equation
I = 10000 × 0.03875 × 5 = 1937.5
I = $ 1,937.50
The simple interest accumulated
on a principal of $ 10,000.00
at a rate of 3.875% per year
for 5 years is $ 1,937.50.

the sum of a number and 5 is between 0 and 12. write the compound inequality and solve
The inequality will be given by 0 < x + 5 < 12 or -5 < x < 7 which meant value of number x will lie between -5 and 7.
What are inequalities ?
When two values are compared , an inequality represents whether one is greater than, less than, or not equal to the other.
It is given that the sum of a number and 5 is between 0 and 12. This can be represented by an inequality.
Let's assume the number is x.
So , the sum of number x and 5 will be :
= x + 5
Also , given that, this value is between 0 and 12 .
This meant the inequality will be given by :
0 < x + 5 < 12
Let's subtract 5 from every term of inequality.
0 - 5 < x + 5 - 5 < 12 - 5
or
-5 < x < 7
The value of x lies between -5 and 7.
Therefore , the inequality will be given by 0 < x + 5 < 12 or -5 < x < 7 which meant value of number x will lie between -5 and 7.

Determine an equation for each
parallel line described.
What is the equation of a line
parallel to y = -5x + 3 that
passes through (3, 1)?
Answer:
y = -5x + 16
Step-by-step explanation:
Parallel lines have the same slope. The slope is -5. We need to find the y-intercept. We will use the slope(-5) the x (3) and the y (1) to find this.
y = mx + b Plug in what we know
1 = -5(3) + b
1 = -15 + b Add 15 to both sides
16 = b
y = mx + b
y = -5x + 16

Two trains leave New York traveling in opposite directions. The faster train travels 10mph faster than
the slower train. Find the speed of each train if the trains are 270 miles apart after 3 hours.
Answer:
One train is traveling at 40 mph and the other train is traveling at 50 mph
Step-by-step explanation:
Distance = rate times time
If I add the two rates and times together, I will get the total distance
Train 1
Rate x + 10
Time 3
Train 2
Rate x
Time x
3(x + 10) + 3x = 270 Distribute the 3
3x + 30 + 3x = 270 Combine like terms
6x + 30 = 270 Subtract 30 from both sides of the equation
6x = 240 Divide both sides by 6
x = 40 This is the slower train. Add 10 for the faster train.
A teacher is handing out markers to students. She has only 100 markers to hand out to her 18 students. Write and solve an inequality to represent the number of markers each student will receive. Assume each person gets the same number of markers. Use x as your variable.
Answer:
100 >/ 18x = ~5 markers
Step-by-step explanation:
The teacher can only hand out 100 markers or less. Not more. We can't get to exactly 100 with an interger as our answer. I got 18x from the fact that there are 18 students. X represents how many markers each one will get. X equals 5.555 repeating, but you can't have a decimal amount of markers, but you can't round up. That would mean that the teacher gave out 108 markers. That's not possible.
