Explain the differences between properties of equality
and properties of inequality when solving equations and
inequalities.
Answer:
In algebra, an equation is a mathematical expression that contains an equals sign. ... An inequality is a mathematical expression that contains inequality signs. For example, y≤ 12x is an inequality. Inequalities are used to tell us that an expression is either larger or smaller than another expression.

If I was asked to think of a number and multiply it by 2, I could
write this algebraically as 2x.
Write the following algebraically, using x as your unknown.
"I think of a number, take away 1 and multiply the result by 3."
Please answer
you didn't say what number you would think of
I'm guessing this is multiple choice but the formatting of the question is a bit hard to understand.
write it algebraically as 2x
2x just means multiply x by 2
The algebraic equation for the other example is 3(x-1) which is 3x - 3
This is not multiplying by two, so it is wrong.

The automaker of your new car recommended an oil change following the 5,000 miles and then every 3,000 miles thereafter.if you plan to drive the car 250 miles a week, how many oil changes will you need the first year?
Answer:
3 oil changes
Step-by-step explanation:
1. Find an equation that represents this word problem: 3000x + 5000 = y
Where y = the # of miles total. y = 250 miles/week * 52 weeks/year = 13000 miles.
2. Solve for x: 3000x + 5000 = 13000 3000x=8000
3. x = 8/3 integer round down x = 2 oil changes, but plus the one after 5000 miles is a total of 3 oil changes that year

Kristi gets $10 a week from her parents if she washes the dishes after dinner every night. Kristi has saved up $30 over the last few weeks from her allowance. She wants to continue saving her allowance until she has enough money to buy the $7o bike she saw at the store last week. Assuming Kristi receives her allowance every week, write an equation that shows how many more weeks Kristi has to save her allowance to buy the bike, where w is the number of weeks. You can solve the equation to check your answer.
Answer: She needs to save her allowance for another 4 weeks.
Step-by-step explanation:
She starts with $30, and for each week that she saves her allowance, she gets another $10. If she saves for "w" weeks, she has:
$30 + w*$10
And she wants to have $70
$30 + w*$10 = $70
We can solve this:
$30 + w*$10 = $70
w*$10 = $70 - $30 = $40
w = $40/$10 = 4

Remark
This is one of those questions whose answer is hidden by the sloppiness of the wording. You don't really know what the starting speed is at 129 feet. I am going to assume the submarine is constantly moving at the same speed.
Givens
d1 = 129
d2 = 229
t = 3 sec
formula
(d2 - d1) = r * t
solution
(229 - 129) = r * t
100 = r * 3
100/3 = r
33.3 feet/s = r
Caution
if you know what d = vi*t + 1/2*a * t^2 is, you could get this wrong. If you do know the formula, leave a comment below my answer.

25, 36, 49, 64, ...
Answer:
81
Step-by-step explanation:
25, 36, 49, 64, ...
36 - 25 = 11
49 - 36 = 13 = 11 + 2
64 - 49 = 15 = 13 + 2
64 + 15 + 2 = 81

Demi’s last 5 bowling scores were 68, 75, 90, 80. What was Femi’s mean score? A.72 B.75 C.77 D.79 D.
Complete Question:
Femi's last 5 bowling scores were 68, 75, 72, 90, and 80. What was Femi's mean score?
Answer:
Step-by-step explanation:
Given
Scores: 68, 75, 72, 90, and 80
Required
Determine the mean
The mean (M) of a data is calculated as thus:
[tex]M = \frac{\sum x}{n}[/tex]
Where
n = number of data.
In this case,
n = 5
and
[tex]\sum x[/tex] = sum of data
So, the formula becomes
[tex]M = \frac{68 + 75 + 72 + 90 + 80}{5}[/tex]
[tex]M = \frac{385}{5}[/tex]
[tex]M = 77[/tex]
Hence, the mean is 77

If g(x)= -3x^3+5x-3, then the slope of the line that is perpendicular to the tangent line at x=1 would be...
A. 4
B. -4
C. 2
D. -1/4
E. 1/4
The slope of the line that is perpendicular to the tangent line at x=1 is, [tex]\frac{1}{4}[/tex]
Option E is correct.
Slope of line:The derivative of given function with respect to x is known as slope of function.
Given function is, [tex]g(x)=-3x^{3}+5x-3[/tex]
Now differentiate the above function.
[tex]\frac{dg(x)}{dt}=-9x^{2} +5[/tex]
[tex]\frac{dg(x)}{dx}[/tex] at [tex]x=1[/tex] is,
[tex]\frac{dg}{dt} =-9(1)^{2}+5 =-4[/tex]
the slope of the line that is perpendicular to the tangent line at x=1 is,
Slope[tex]=-\frac{1}{dg/dx}=\frac{1}{4}[/tex]

Caitlin drew a scale drawing of the community park in her town. The actual
long.
What scale did Caitlin use to draw the park?
o 1 inch equals 4 feet
4 inches equal 4 feet
o 1 inch equals foot
4 inches equal 1 foot
Answer: 1 inch equals 4 feet
Step-by-step explanation:
By an online search, I´ve found that:
The park is 48 ft long.
Caitlin´s drawing is 12 inches long.
To find how much each inch represents, we need to take the quotient between those lengths:
48ft/12in = 4ft/in.
We also can write this amount as:
4 feet per inch.
This means that each inch represents 4 feets.
Then the correct option is the first one: 1 inch equals 4 feet
A cell phone plan costs $150 to start, Then, thero is a $50 charge each month. What is
the total cost, y, for x months? Which equation match this situation Y=150-50x. Y=50x+150. Y=150x+50. -50x+150=y
Answer:
Y = 50x + 150
Step-by-step explanation:
50 per month (x = unknown number of months) === 50x
$150 is the starting charge (automatic +150)
Y = total cost
Y = 50x + 150
