Step-by-step explanation:
Hundredth is the second digit after the decimal so use the third digit to round the second.

If the digit you are using to round is [tex]\geq[/tex]5 then round up.
A line passes through the points (0, –5) and (8, –10). What is its equation in slope-intercept form?
Answers
Answer:
y=-[tex]\frac{5}{8}[/tex]x-5
Step-by-step explanation:
Start with the slope equation [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex].
[tex]\frac{-10-(-5)}{8-0}=\frac{-5}{8}[/tex]
This is the slope of your equation
Now rearrange the slope-intercept equation to get your y-intercept
y=mx+b
y-mx=b
Now substitute either of your two points to find your y-intercept
-10-(-[tex]\frac{5}{8}[/tex](8))=b
-10-(-5)=b
-10+5=b
b=-5
Now that you have slope and the y-intercept you can write your equation:
y=-[tex]\frac{5}{8}[/tex]x-5

What value of x makes the equation -5x - (-7 - 4x) = -2(3x - 4) tru
Answers
Answer: 1/10 or 0.1
Step-by-step explanation:
-(-7 - 4x) = -2(3x - 4)
7 + 4x = -6x + 8
* subtract 7 from both sides
4x = -6x + 1
* Add 6x to both sides
10 x = 1
* Divide both sides by 10
x = 1/10 or 0.10
This step makes sure that you know to distribute the negative.
-5x + [-(-7-4x)] = -2(3x-4)
Continue to simplify. Start by distributing across the parentheses.
-5x+(7+4x)= -6x+8
-5x+4x+7= -6x+8
-x+7=-6x+8
Once you can’t simplify either side any more, you try and isolate the variable onto one side.
-x+7=-6x+8
+x. +x
________
7=-5x+8
Then isolate the constants into one side.
7=-5x+8
-8. -8

-1=-5x
Then make sure you have the variable being multiplied only once.
-1= -5x
—. —
-5. -5

And then move your variable to the left.
x=0.2
The value of x that makes the equation true is 0.2

A truck can be rented from Company A for $90 a day plus $0.20 per mile. Company B charges $30 a day plus $0.60 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
Answers
Answer: 150 miles
Step-by-step explanation:
Let A stand for Company A's Total Price, and B for Company B. Let x be the number of miles driven.
A = $90 + ($0.20/mile)*x
B = $30 + ($0.60/mile)*x
We want to know for what x does A = B
$90 + ($0.20/mile)*x = $30 + ($0.60/mile)*x
$60 + ($0.20/mile)*x - ($0.60/mile)*x = 0
$60 + x*($0.20/mile) - ($0.60/mile)) = 0
$60 + x*(- ($0.40/mile)) = 0
x*(- ($0.40/mile)) = -$60
x = -$60/(-$0.40/mile)
x = 150 miles
Company A, 1 day, 150 miles = $120
Company B, 1 day, 150 miles = $120
At 150 miles, and just 1 day, both companies will charge a total of $120 for the rental.
Airfare from Atlanta, GA to Nashville,TN was decreased from $250 to $180. By what percentage did the cost of the airfare change?
Answers
Answer:A decrease of 28%
Step-by-step explanation: the question says decreased so you can mark out A and B then 250-180 is 70, 70% of 250 is 28%
The percentage is the indicating hundredth thus the percentage change from $250 to $180 is 28%.
What is the percentage?
The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
As per the given question,
Initial price of Airfare = $250
Final price of Airfare = $180
The percentage = change/initial × 100
Percentage decrease = (250 - 180)/250 × 100
⇒ 0.28 × 100 = 28%
Hence "The percentage is the indicating hundredth thus the percentage change from $250 to $180 is 28%".

use the model to solve for X.
Answers
Answer:
X=3
Step-by-step explanation:
First you subtract 3x from both sides to keep x on one side.
5x minus 3x is 2x.
Then you subtract 1 from both sides to keep the variable alone.
7 minus 1 is 6.
Then you divided both sides by 2.
2x divided by 2 is x and 6 divided by 2 is three.
Then all you have left is x=3
