Answer:
1. -564
2. 11 1/2
3. 45/472
5. 3(2x - 1) = 3(2x) - 3(1)
6. 1/5(x) + 2y
= x/5 + 2y
7) 77.1km
8. 211.8 pizzas
Step-by-step explanation:
1. 4 (6) -2 (8) + 4-576
= 24 - 16 + 4 - 576
= 24 + 4 - 16 - 576
= 28 - 16 - 576
= 28 - 592
= -564
2. 2 3/4 + 8 3/4
Mínimo común múltiplo de los denominadores = 4
2 3/4 + 8 3/4
= (2 + 8) + (3 + 3/4)
= 10 + (6/4)
= 10 + 1 2/4
= 10 +1 1/2
= 11 1/2
3. (9/4) (6/59 (1/2) 2/6 ÷ 6/5
BODMAS
= 9/4 × 6/59 × 1/2 × 2/6 ÷ 6/5
= 9/4 × 6/59 × 1/2 × 2/6 × 5/6
= 45/472
5. Expresar el lenguaje común 6x -3

It would take Delia 3 hours longer to re tile their bathroom by herself than it would for kari to retile on her own. If they work together it would take them 2 hours to retile their bathroom. How long would it take for Delia to retile the bathroom alone?
Answer:
6hours
Step-by-step explanation:
From the given information:
Suppose it took Karl x hours to retile her bathroom,
Then it will take Della 3 hours longer i.e (3+x) hours
If Della and Karl work together or will take them 2 hours
The objective is to determine how long it will take Delia to retile the bathroom alone?
∴
[tex]\dfrac{1}{x}+\dfrac{1}{3+x}= \dfrac{1}{2}[/tex]
[tex]\dfrac{x+3+x}{x(3+x)}= \dfrac{1}{2}[/tex]
[tex]\dfrac{2x+3}{3x+x^2}= \dfrac{1}{2}[/tex]
By cross multiplying, we have:
2(2x+3) = 3x+x²
4x + 6 = 3x + x²
3x + x² - 4x - 6
x² - x - 6 = 0
Using quadratic equation
x² -3x +2x - 6 = 0
x(x - 3) + 2(x - 3) = 0
(x +2) (x - 3) = 0
x + 2 = 0 or x - 3 = 0
x = -2 or x = 3
Since we are concerned about the positive integer,
Then, Karl = x = 3 hours while Della which is (3+x) = 3+3 = 6hours
Una empresa comercial vende automóviles cuyo precio es de S/.60000, con una cuota inicial del 20 % , para cancelar el saldo en treinta meses de plazo . Calcula la cuota fija mensual que se pagara si la empresa cobra una tasa de interes simple del 12% semestralmente
Responder:
$ 2560
Explicación paso a paso:
Dado lo siguiente:
Importe total (A) = 60000
Pago inicial = 20% de A
Pago inicial = 0,2 * 60000 = 12000
Importe pendiente de pago = (60000 - 12000) = 48000
Calcular el interés simple sobre el saldo de 48000 = principal
principal * tasa * tiempo
(48 000 * 0,12 * (30/6))
48000 * 0,12 * 5 = 28800
Por tanto, el importe total a pagar durante 30 meses será:
(48 000 + 28800) = 76800
Dado que el pago mensual es fijo:
Pago mensual = (monto total a pagar / cantidad de meses)
Pago mensual = (76800/30)
Pago mensual = $ 2560
The heaviest land animal ever recorded (according to the Guinness Book of World Records) was a male African bush elephant. He weighed 13.5 tons measured to the nearest half-ton. How would you find the elephant’s minimum and maximum possible weights?
Answer:
The largest African elephant weighed 13.5 tons (27,000 pounds) The world record holder weighed this much and stood 13ft/4m tall at the shoulder. There are other species of elephants, namely the Asian and the Indian, but they are much smaller than the African. The African elephant is the king among the giants on land. No other land animal comes close to the size of these creatures. It would take 165 full-grown men to make up the same weight as the world's record African elephant. The noise of an elephant digesting its food (when its tummy's growling) can be heard up to 600ft/183m away. Elephants actually have control over their digestive processes because they are able to stop the sounds of digestion when they sense danger. Here are some other cool elephant factoids:

What is the y-intercept of 3x+5y=−30 ?
(0,−6)
(−6,0)
(10,−6)
(0,10)
Answer: (0,-6)
Step-by-step explanation:
To find the y-intercept, we can rewrite the equation into slope-intercept form.
3x+5y=-30 [subtract both sides by 3x]
5y=-3x-30 [divide both sides by 5]
y=-3/5x-6
Now that the equation is in slope-interceot form, we know that the y-intercept is -6, we know that the answer is (0,-6).

Supplementary angles are angles that sum up to 180 degrees
Step 1:
If m<x and m<y are supplementary, hence;
m<x + m<y = 180 ....................1
Step 2:
If m<y is a supplement to m<z, hence:
m<y + m<z = 180 ...........................2
Equating 1 and 2
m<x + m<y = m<y + m<z
Subtract m<y from both sides
m<x + m<y-m<y = m<y + m<z - m<y
m<x = m<z
This proves the statement m<x = m<z

A college has a financial aid formula that applies to applicants whose family's income is below a certain threshold. The financial aid can be determined by the function f(x)=25000+3000x,f(x)=25000+3000x, where xx is the number of siblings (including half siblings and step siblings) that the applicant has living in their household. Find and interpret the given function values and determine an appropriate domain for the function.
The values of the function are,
f (- 3) = 16,000 meaning a qualifying applicant with - 3 siblings in their household would get $16,000 in financial aid. This interpretation does not make sense in the context of the problem.
f (3) = 34,000 meaning a qualifying applicant with 3 siblings in their household would get $34,000 in financial aid. This interpretation makes sense in the context of the problem.
The domain for this function is x ≥ 0, indicating that the number of siblings must be a non-negative whole number or zero.
Given that,
The function is,
[tex]f (x) = 25000 + 3000x[/tex]
Where x is the number of siblings.
Hence, the values of the function are found as,
[tex]f (x) = 25000 + 3000x[/tex]
Put x = - 3;
[tex]f (- 3) = 25000 + 3000 \times - 3[/tex]
[tex]f (- 3) = 25000 - 9000[/tex]
[tex]f (- 3) = 16,000[/tex]
Put x = 3;
[tex]f (x) = 25000 + 3000x[/tex]
[tex]f (3) = 25000 + 3000 \times 3[/tex]
[tex]f ( 3) = 25000 + 9000[/tex]
[tex]f (3) = 34,000[/tex]
Since the given function is,'
[tex]f (x) = 25000 + 3000x[/tex]
Regarding the domain of the function,
Since the number of siblings (x) must be a non-negative integer, it represents the count of individuals.
Therefore, the appropriate domain for this function would be x ≥ 0, meaning x can be any non-negative whole number or zero.

Write the equation of the line that passes through the points
(-2, -1) and (2, 4). Put your answer in fully reduced point-
slope form, unless it is a vertical or horizontal line.
Answer:
Step-by-step explanation:
Step 1 : Find the slope/gradient (this is known as "m")
The slope formula is :
[tex]m = \frac{y2 - y1}{x2-x1}[/tex]
*Note that we are given 2 points:
For the first point (-2,-1) , this means x1 = -2 and y1 = -1
For the second point (2,4), this means x2 = 2 and y2 = 4
If we substitute those values into the slope formula you end up with this:
[tex]m = \frac{y2-y2}{x2-x1} = \frac{4 - (-1)}{2 - (-2)} = \frac{4+1}{2+2} =\frac{5}{4}[/tex]
Step 2: Substitute the values into the point-slope formula:
[tex]y - y1 = m(x- x1)[/tex]
Now that we know m = 5/4 , you can substitute this into the above formula and you get:
[tex]y - y1 = m(x- x1)[/tex]
[tex]y - (-1) = \frac{5}{4} (x - (-2)) \\y + 1 = \frac{5}{4} ( x + 2)[/tex]
[tex]y = \frac{5}{4}(x + 2) - 1[/tex]

What number must be subtracted from both the numerator and the denominator of 5/3 to obtain a Fraction equal to 5/7 ?
Answer:
Step-by-step explanation:
Let the number = x
So we are trying to work out what number must be subtract from the numerator and denominator of 5/3 to equal 5/7.
You can write this as:
[tex]\frac{ 5-x}{3 - x} = \frac{5}{7}[/tex]
Then you want to get rid of the fractions so multiply both sides by 3-x
[tex]5 - x =[/tex] [tex]\frac{5 ( 3 - x)}{7}[/tex]
Then multiply both sides by 7
[tex]7( 5 - x) = 5 ( 3 - x)[/tex]
Multiply it out.
35 - 7x = 15 - 5x
Add 7x to both sides:
35 = 15 - 5x + 7x
35 = 15 + 2x
Subtract 15 from both sides
35 - 15 = 2x
20 = 2x
To find x, divide both sides by 2.
x = 10.

4 to the power of -1
Answer:
0.25
I hope this helps!
Answer:
1/4
Step-by-step explanation:
Negative exponents basically flip the number upside down,
so 4 ^ -2 would be 1/4^2
where the four has a power of 2.
The answer would therefore be 1/16
Numbers to the power of 1, is just the same number, so if you have negative exponents, it would be the same 4, except flipped over.
