Answer:
I can only assume that the entire 1-4x is divided by 2x, and 4 by all of 1 - 5x. You can guarantee more accurate results by using brackets where appropriate. If I read that expression with the correct notation, it reads as [tex]1 - \frac{4x}{2x} + 1 = \frac{4}{1} - 5x[/tex].
Assuming instead that it's meant as [tex]\frac{1 - 4x}{2x + 1} = \frac{4}{1 - 5x}[/tex], we can solve it as shown below, giving us x values of 1 and 3/20 (or 0.15).
Step-by-step explanation:
First let's reformat this to the usual ax² + bx + c format:
[tex]\frac{1 - 4x}{2x + 1} = \frac{4}{1 - 5x}\\(1 - 4x)(1 - 5x) = 4(2x + 1)\\1 - 5x - 4x + 20x^2 = 8x + 4\\20x^2 - 5x - 4x - 8x + 1 - 4 = 0\\20x^2 - 17x - 3 = 0[/tex]
Let's solve it with the quadratic formula:
[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac} }{2a}\\\\x = \frac{17 \pm \sqrt{-17^2 - 4\times 20 \times( -3)} }{2\times20}\\\\x = \frac{17 \pm \sqrt{289 + 240} }{40}\\\\x = \frac{17 \pm 23 }{40}\\\\x = 1, \frac{3}{20}[/tex]

The fun guys game rental store charges an annual fee of $5 plus $6.50 per game rented. The game bank charges an annual fee of $17 plus $3.50 per game. For how many games rentals will the cost be the same at both stores? What is that cost?
Answer:
A. 4 games
B. $31
Step-by-step explanation:
Fun guys game rental store:
5 + 6.50x
Game bank:
17 + 3.50x
Where,
x = number of games
For how many games rentals will the cost be the same at both stores?
Equate the charges of both stores
5 + 6.50x = 17 + 3.50x
5 - 17 = 3.50x - 6.50x
12 = 3x
Divide both sides by 3
x = 12/3
= 4
x = 4 games
What is that cost?
Game bank:
17 + 3.50x
= 17 + 3.50(4)
= 17 + 14
= $31

Adrian Beltre hit 48 home runs during the 2004 Major League Baseball season, but only hit 19 home runs in the 2005 season. By what percent did Beltre's home run production decrease from 2004 to 2005?
Answer:
60.42%
Step-by-step explanation:
Number of home runs hit by Adrian Beltre in 2004 = 48
Number of home runs hit by Adrian Beltre in 2005 = 19
To find:
Percentage decrease in home run production from 2004 to 2005.
Solution:
To find the percentage decrease, first of all we need to find the decrease in the number of home runs and then we will divide with the number of home runs in 2004 and then finally will multiply the result with 100 to get the percentage decrease.
Decrease in the number of home runs = Number of home runs in 2004 - Number of home runs in 2005 = 48 - 19 = 29
[tex]\text{Percentage of decrease in Home runs} = \dfrac{\text{Decrease in home runs}}{\text{Number of home runs in 2004}}\times 100\\\Rightarrow \text{Percentage of decrease in Home runs} = \dfrac{29}{48}\times 100 \approx \bold{60.42\%}[/tex]
Therefore, by 60.42% Beltre's home run production has decreased from 2004 to 2005.
Percent decrease from 2004 to 2005 is 60.14%
Given that;Number of home run hit in 2004 = 48
Number of home run hit in 2005 = 19
Find:Percent decrease from 2004 to 2005
Computation:Percent decrease from 2004 to 2005 = [(48 - 19) / 48]100
Percent decrease from 2004 to 2005 = [(29) / 48]100
Percent decrease from 2004 to 2005 = 60.14%

Tamara has a cell phone plan that charges $0.07 per minute plus a monthly fee of $19.00. She budgets $29.50 per month for total cell phone expenses. What is the maximum number of minutes Tamara could use her phone each month in order to stay within her budget?
Answer:
525 minutes
Step-by-step explanation:
Given that the monthly fee for the phone is $19 and the call charges rate is $0.02 per minute.
Her monthly budget is $29.50.
Let Tamara can make a maximum number of n minutes call in a month.
So, call charges for n minutes = $0.02n
Total monthly expenses on her phone = 19+0.02n
As her monthly budget is $29.50.
So, 19+0.02n=29.50
0.02n=29.50-19
0.02n=10.50
n=10.50/0.02
n=525
Hence, she can make a maximum of 525 minutes call.

Consuela drew this figure. Which pair of segments appears to be congruent?
The probability of spinning an even number and flipping heads is..
Answer: 20% Chance
Step-by-step explanation:
Probability of flipping heads on a coin is 50% and this wheel landing on a even number is 40% you multiply .50 and .40 and you get .20.
Probability of spinning an even number and flipping heads P(A∩B) = (2 / 10).
What is probability?
" Probability is a mathematical expression which represents ratio of number of favourable outcomes to the total number of outcomes."
Formula used
Probability= (Number of favourable outcomes) / (Total number of outcomes)
For Independent Event
P(A∩B) = P(A)×P(B)
According to the question,
'A' represents the probability of spinning an even number
'B' represents the probability of flipping heads
Possible outcomes on spinner = { 1, 2, 3, 4, 5}
Favourable outcomes of spinning an even number = 2
Total number of outcomes = 5
Substitute the value in the formula we get,
P(A) = ( 2 / 5)
Possible outcomes of flipping a coin = { head , tail}
Total outcomes of flipping a coin =2
Favourable outcomes flipping heads = 1
P(B) = (1 / 2)
Probability of spinning an even number and flipping heads P(A∩B)
A and B are independent events
Substitute the value of P(A) and P(B) in the formula we get,
P(A∩B) = ( 2/ 5)×(1/2)
= 2 /10
Hence, probability of spinning an even number and flipping heads P(A∩B) = (2 / 10).
