Answer: The answer to this is x= -9/4
Answer:
[tex]\boxed {x = - \frac{9}{4}}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex] :
[tex]-2(x + \frac{1}{4}) + 1 = 5[/tex]
-Use Distributive Property:
[tex]-2(x + \frac{1}{4}) + 1 = 5[/tex]
[tex]-2x + \frac{-2}{4} + 1 = 5[/tex]
-Reduce the fraction [tex]\frac{-2}{4}[/tex] to the lowest terms by canceling out [tex]2[/tex] :
[tex]-2x + \frac{-2}{4} + 1 = 5[/tex]
[tex]-2x - \frac{1}{2} + 1 = 5[/tex]
- Convert the integer [tex]1[/tex] to [tex]\frac{2}{2}[/tex] :
[tex]-2x - \frac{1}{2} + 1 = 5[/tex]
[tex]-2x - \frac{1}{2} + \frac{2}{2} = 5[/tex]
-Since both fractions [tex]-\frac{1}{2}[/tex] and [tex]\frac{2}{2}[/tex] have the same denominator, you add the numerators together:
[tex]-2x - \frac{1}{2} + \frac{2}{2} = 5[/tex]
[tex]-2x + \frac{1}{2} = 5[/tex]
-Change the integer [tex]5[/tex] to [tex]\frac{10}{2}[/tex] and subtract [tex]\frac{1}{2}[/tex] on both sides. Then, when both fractions have the same denominator, you subtract them, by subtracting the numerators:
[tex]-2x + \frac{1}{2} - \frac{1}{2} = \frac{10}{2} - \frac{1}{2}[/tex]
[tex]-2x = \frac{9}{2}[/tex]
-Divide by Multiplying [tex]2[/tex] and [tex]-2[/tex] :
[tex]\frac{-2x}{-2} = \frac{9}{2 (-2)}[/tex]
[tex]x = \frac{9}{-4}[/tex]
-Rewrite the answer:
[tex]x = \frac{9}{-4}[/tex]
[tex]\boxed {x = - \frac{9}{4}}[/tex]
Solvefor x. x+3/5 =2
Answer: x=7/5 or 1 2/5
Step-by-step explanation:
Given
x+3/5=2
Subtract 3/5 on both sides
x+3/5-3/5=2-3/5
x=10/5-3/5 (This is to convert 2, as a integer, to a fraction in order to ease the
x=7/5 operation)

Which expression is equivalent to this polynomial expression? (2a – 36)(2a2 + 662) + (6a26 + 12a62 – 783)
Answer:
1. Look for factors that each term has in common.
They all have a "b" so factor that out.
a2b + 2ab - 8b = b(a2 + 2a - 8)
2. Factor the remaining polynomial.
Factors of -8 that add to 2 are 4(-2)
a2 + 2a - 8 = (a+4)(a-2)
Final answer: b(a+4)(a-2)

A publisher needs to send many books to a local book retailer, and will send the books in a combination of small and large boxes. Each small box can hold 20 books and each large box can hold 45 books. How many books could be shipped using 5 small boxes and 7 large boxes? How many books could be shipped using s s small boxes and l l large boxes?
Answer:
a, [tex]Books = 315[/tex]
b, [tex]Total = 20s + 45l[/tex]
Step-by-step explanation:
Given
[tex]Small\ Box = 20[/tex]
[tex]Large\ Box = 45[/tex]
Solving (a): Books using 5 small and 7 large boxes;
This is calculated as follows
[tex]Books = Size * quantity[/tex]
For Small box
[tex]Books = 20 * 5[/tex]
[tex]Books = 100[/tex]
For large box:
[tex]Books = 45 * 7[/tex]
[tex]Books = 315[/tex]
[tex]Total = 100 + 315[/tex]
[tex]Total = 415\ books[/tex]
Solving (b): s small and l large
We use the same concept as (a) above:
For Small Box
[tex]Books = 20 * s[/tex]
[tex]Books = 20s[/tex]
For large box
[tex]Books = 45 * l[/tex]
[tex]Books = 45l[/tex]
[tex]Total = 20s + 45l[/tex]

Daryl has a total of 120 national football league (NFL) trading cards from both the American football conference(AFC) and the national football conference (NFC). The number of AFC cards is 5 more than four times the number of NFC cards . Which system of equations can be used to find how many AFC cards, A and NFC cards,N, Daryl has?
Answer:
A = 4N + 5
A + N = 120
Step-by-step explanation:
Given that
A = Number of AFC cars
N = Number of NFC cards
And, Total cards is 120
Now
the equation would be
A + N = 120
Also
The number of AFC is 5 more than 4 times the number of NFC cards
So,
A = 4N + 5
Therefore
A = 4N + 5
A + N = 120
Hence, the system of equations that should be used is A = 4N + 5 and A + N = 120 respectively

the volume of the truck is 162 yards. To find how many cubes will fit in each dimension, divide that length by the side of the cube
Answer:
180 cubes would be fit inside the truck
Step-by-step explanation:
well we know 1 cube is 1/10 of a yard
so let’s make it a easier number and say 10 cubes is 1 yard (you multiply 10 on each side, as long as you multiply the same number, which can be any number but I use 10 since it’s easier, on both sides, it’ll be the same thing.
so 162/10=16
So 16, 10 cubes si we multiply those two and you’ll get 160.
But there’s 2 yards not filled yet, we know that 1 yard is 10 cubes, so 2 yards would be 20 cubes.
so 160+20=180
180 cubes

Solve the proportion for X.
3X 120
----- = ------
24 192
Answer:
x = 5
Step-by-step explanation:
There are two possible ways to look at this equation, but each way the answer is the same
first
(3x / 24) = (120 / 192)
solve using cross products
24 * 120 = 3x * 192
2880 = 576 x
/ 576 /576
5 = x
second
(3x / 120) = (24 / 192)
solve using cross products
3x * 192 = 24 * 120
576 x = 2880
/576 /576
x = 5

how to solve this sum with detailed explaination
Answer:
A = (- 1, 0 ) and B = (4, 0 )
Step-by-step explanation:
Given
y = x² - 3x - 4
To find the x- intercepts, let y = 0, that is
x² - 3x - 4 = 0
Consider the factors of the constant term (- 4) which sum to give the coefficient of the x- term (- 3)
The factors are - 4 and + 1 , since
- 4 × 1 = - 4 and - 4 + 1 = - 3, thus
(x - 4)(x + 1) = 0
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4 ⇒ point B
x + 1 = 0 ⇒ x = - 1 ⇒ point A

As an aid to the establishment of personnel requirements, the director of a hospital wishes to estimate the mean number of people who are admitted to the emergency room during a 24-hour period. The director randomly selects 64 different 24-hour periods and determines the number of admissions for each. For this sample, X = 396 and S = 100. Using the sample standard deviation as an estimate for the population standard deviation, what size sample should the director choose if she wishes to estimate the mean number of admissions per 24-hour period to within 1 admission with 99% reliability, what size sample should she choose?
Answer:
Sample size n = 16
Step-by-step explanation:
We use the formula for Margin of Error for the question
Margin of Error = z × Standard deviation/√n
Margin of Error = 1
z score for 99% confidence interval = 2.576
Standard deviation = 100
1 = 2.576 × 100/√n
1 × √n = 257.6
√n = 257.6/1
n = √257.6
n = 16.049922118
Approximately = 16
Therefore, the sample size = 16

in a standard deck of t2 playing cards, there are 4 aces, 4 kings, 4 queens, and 4 Jacks. All other cards have number values. the kings, queens, and Jack's are called face cards. You are dealt 2 cards in a sequence. calculate the probability of being dealt a 3 and then a 10. write your answer as a decimal to the nearest hundredth
Answer:
0.01
Step-by-step explanation:
Assuming the deck is the national playing deck with 52 cards.
Your probability of getting a 3 from the entire deck is 4/52. This number is the same for 10.
To get the probability of pulling a 3 and a 10 afterwards, you must multiply these two fractions (you're expecting a lower percentage).
[tex]4/52 * 4/52 = 0.0059[/tex]
