Step-by-step explanation:
Equation for Fast Internet is
45 + 50.45x
Equation for Quick Internet is
57.95x
To find when they cost the same , equate the 2 equations
45 + 50.45x = 57.95x ← required equation
Solve the equation by subtracting 50.45x from both sides
45 = 7.5x ( divide both sides by 7.5 )
6 = x
Both services would cost the same after 6 months
Suppose a book has 100 names listed in each column, with 5 columns per page. The book has 200 pages.
How many books are needed to list all the people in a population of 200 million?
Answer:
2,000
Step-by-step explanation:
We know that 100 × 5 = 500, so one page has 500 names on it, we can now then infer that each book has 100,000 names on it because we do 500 × 200.
So knowing that there is 100,000 names per book we now then do 100,000 × 2,000 which equals 200,000,000, so we need to do 2,000 books to store the names of 200 million people. Hope this helps.

Answer:
the triangle above is an isoceles triangle
therefore the base angles are equal
So we have:
X + X + 38= 180
2x = 180-38
2x = 142
X = 71°
Answer:
71
Step-by-step explanation:
The two line of length 21 defines that the base angles are equal.
so therefore.
38 degrees + x degrees + x degrees = 180
38 + 2x = 180
2x = 180 - 32
2x = 142
x = 71.

Solve.
|x|−5=−20

no solution
–100 or 100
100
Answer:
No Solution
Step-by-step explanation:
We are given the equation:
[tex]\displaystyle \large{|x|-5=-20}[/tex]
First, Add both sides by 5 which leaves us [tex]\displaystyle \large{|x|=-15}[/tex]
By definition, an absolute value cannot be negative. There are no x-values that can equal to -15 because no matter what real numbers you put in or substitute, it will never become negative.
Hence, no solution.

Enter the value of 14 + (-22) – 14 – 22.
Answer:
-44!
Step-by-step explanation:
I’m going to try and explain this the best way possible through a keyboard:
14+(-22)-14-22
I usually work from left to right with these kinda problems, it helps me stay organized.
The rule for adding integers is when the signs are different you always subtract and take the sign of the LARGER number…
With that being said,
14+-22=-8
Then re write the problem
-8-14-22
Subtracting integers with different sign calls for the KCF method (keep the first number the same, change the sign, flip the second number:
Working one step at a time left to right…
-8+-14 (just add normally and keep the sign)
-22-22
Again using the kcf method,
-22+22=
-44
Hope that helps!

what is 0.04 km, 420 cm, 4,600 mm, and 4.3 meters in order from least to greatest
Answer:
420 cm, 4.3 meters, 4600 mm, 0.04 km
Step-by-step explanation:
We can solve this by converting each to the same unit. I will be using meters.
0.04 km
1 km = 1000 meters
1000 meters / 1 km = 1
multiply 0.04 km by 1 = 1000 meters / 1 km , keeping the km at the bottom to cross out
0.04 km * 1000 meters / 1 km = 40 meters
420 cm
100 cm = 1 meter
1 meter / 100 cm = 1
multiply 420 cm by this, keeping cm at the bottom so it crosses out
420 cm * 1 meter / 100 cm = 4.2 meters
4600 mm
1000 mm = 1 meter
1 meter / 1000 mm = 1
4600 mm * 1 meter / 1000 mm = 4.6 meters
Therefore, our order is
420 cm, 4.3 meters, 4600 mm, 0.04 km

What is mean by Ratio?
A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.
Where, x and y are individual amount of two quantities.
And, Total quantity gives after combine as x + y.
Given that;
Jackson answered every 7 out of 9 questions correctly on a Spanish Quiz.
Total number of questions = 63
Now,
Let number of correct questions = x
So, By the definition of ratio, we can formulate;
⇒ 7 : 9 = x : 63
Solve for x as;
⇒ 7 : 9 = x : 63
⇒ 7 / 9 = x / 63
⇒ 7 × 63 / 9 = x
⇒ x = 7 × 63 / 9
⇒ x = 7 × 7
⇒ x = 49
Thus, There are 49 questions did Jackson answer correctly.

What is the slope of the line that passes through the points ( 5 , − 10 ) (5,−10) and ( 11 , − 12 ) ? (11,−12)? Write your answer in simplest form.
The slope of the line that passes through (5,−10) and ( 11 , − 12 ), in simplest form is: -1/3
Recall:
The slope of a line passing across through two points can be calculated using: [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]Given two points:
(5,−10) and ( 11 , − 12 )
Let,[tex](5,-10) = (x_1, y_1)\\\\( 11 , - 12) = (x_2, y_2)[/tex]
Substitute[tex]m = \frac{-12 - (-10)}{11 - 5}[/tex]
Slope (m) = -2/6
Slope (m) = -1/3
Therefore the slope of the line that passes through (5,−10) and ( 11 , − 12 ), in simplest form is: -1/3
