solve for x
2/3x - 4 1/2 = -8
Answer:
The answer is x= -5 1/4
Step-by-step explanation:
Let's solve your equation step-by-step.
2/3x−4 1/2=−8
Step 1: Simplify both sides of the equation.
2/3x+−9/2=−8
Step 2: Add 9/2 to both sides.
2/3x+−9/2+9/2=−8+9/2
2/3x=−7/2
Step 3: Multiply both sides by 3/2.
(3/2)*(2/3x)=(3/2)*(−7/2)
x=−21/4
Answer:
x= −5 1/4

Una compañía suministra electricidad. Cobra $100 mensuales fijos más 15 centavos por kilowatt hora. En los primeros 400 kilowatts suministrados en el mes y cobra 12 centavos por cada kilowatt hora que pase de 400 kilowatts en el mes. ¿Cuál es la función que define al costo?
Answer:
La función resultante es una función a trozos:
[tex]C_{T}(x) = \left\{\begin{array}{cc}100+0.15\cdot x,\,0\le x \le 400\\112+0.12\cdot x,\,x> 400\\\end{array}[/tex]
Step-by-step explanation:
El coste total de la electricidad suministrada ([tex]C_{T}[/tex]), medida en pesos, es la suma del coste fijo ([tex]C_{F}[/tex]) y el coste variable ([tex]C_{V}[/tex]), medidas en pesos.
[tex]C_{T} = C_{F}+C_{V}[/tex] (1)
Ahora, tenemos que el coste fijo es $ 100 mensuales, así:
[tex]C_{F} = \$ \,100[/tex] (2)
Y el coste variable considera que se cobra 15 centavos por kilowatt-hora para los primeros 400 kilowatts-hora y 12 centavos por kilowatt-hora para cada kilowatt-hora que pase de 400 kilowatts-hora en el mes:
(i) Menos o igual que 400 kilowatts-hora:
[tex]C_{V} = 0.15\cdot x[/tex] (3)
Donde [tex]x[/tex] es la electricidad suministrada en kilowatts-hora.
(ii) Mayor que 400 kilowatts-hora:
[tex]C_{V} = 0.15\cdot (400)+0.12\cdot (x-400)[/tex]
[tex]C_{V} = 12+0.12\cdot x[/tex]
La función resultante es una función a trozos:
[tex]C_{T}(x) = \left\{\begin{array}{cc}100+0.15\cdot x,\,0\le x \le 400\\112+0.12\cdot x,\,x> 400\\\end{array}[/tex]
Tyler and frazer weigh a total of 23kg.tyler is 7kg heavier than frazer.How much do they each weigh
Answer:
Frazer is the 8kg and Tyler is 15 kg.
Step-by-step explanation:
Total 23kg. Take away the 7kg, that Tyler weighs more, is 16.
Half the 16 to get 8.
please mark as the brainliest
Tyler and frazer weigh a total of 23kg then Frazer weighs 8 kg and Tyler weighs 15 kg.
Now assume Frazer's weight as x.
According to the problem, Tyler is 7kg heavier than Frazer.
Hence, Tyler's weight will be x + 7.
Now We know that the total weight of both of them is 23 kg.
Therefore, the equation will be:
x + (x + 7) = 23
Simplifying the equation, we get:
2x + 7 = 23
Now, subtracting 7 from both sides of the equation, we get:
2x = 16
Dividing both sides by 2,
x = 8
So, Frazer weighs 8 kg.
Now, we can calculate Tyler's weight as:
x + 7 = 8 + 7 = 15 kg
Therefore, Tyler weighs 15 kg.

Which fraction converts to a repeating decimal number?
OA. 1/12
OB. 7/8
OC. 14/25
OD. 17/20
OE. 6/10
=======================================================
Explanation:
Using a calculator shows that
1/12 = 0.0833333.... where the 3's go on forever7/8 = 0.87514/25 = 0.5617/20 = 0.856/10 = 0.6We see that nearly all of the decimal values are terminating decimals. This means the decimals don't go on forever, so the decimals stop at some point.
Only 0.083333... goes on forever, so that's why 1/12 converts to a repeating decimal number.
----------------------
A way you can determine this without a calculator is to use long division. Or you could use the idea that if the denominator has prime factors other than 2 and 5, then the decimal will repeat forever.
Note how the denominators of the fractions for choices B through E all have prime factors of either 2s only, 5s only, or a mix of 2s and 5s. This fact is why we have terminating decimals here.
In contrast, 12 has prime factorization 2*2*3. That 3 as a prime factor is why the decimal repeats forever.
The only fraction that converts to a repeating decimal number is 1/12.
What is decimal?Decimal is a fraction whose denominator is a power of ten and whose numerator is expressed by figures placed to the right of a decimal point.
Given is to find a fraction that converts to a repeating decimal number.
Repeating decimals are the decimals of the form -
2.7777...
2.34343434...
2.43434343....
Now, we have the fractions and their corresponding decimal numbers as follows -
1/12 = 0.0833333333333333 : Yes7/8 = 0.875 : No14/25 = 0.56 : No17/20 = 0.85 : No6/10 = 0.6 : NoTherefore, the only fraction that converts to a repeating decimal number is 1/12.

slope: 3, y-intercept; 10
Answer:
y = 3x + 10
Step-by-step explanation:
Given that,
Slope = 3
y intercept = 10
We need to write an equation of a line.
The slope-intercept form of a linear equation is given by :
y = mx + b
Where
m is slope and b is y-intercept
Putting all the given values,
y = 3x + 10
Hence, the required equation is "y = 3x + 10"

The language arts teacher wants to know whether the students in the entire school prefer a debate or a speech. The teacher draws a random sample from the following groups:
A - All teachers in the school
B - All boys in each grade
C-All students in the speech club
D-All students in each grade
Which group best represents the population she should take a random sample from to get the best results for her survey?
Answer:
d- all students from each grade
Step-by-step explanation:
Answer:
D, all students in each grade.
Step-by-step explanation:
If you did a random sample from the students in the speech club it will be biased because they will probably all say giving speeches because they are in the speech CLUB. You cannot do the teahcers because their answers will also be biased. If you do all the boys in each grade it will be biased only to what boys like and not girls or any other student in the grade. Therefore, using the process of elimination, the answer is D, you should take a random sample of all the students in each grade.
You are tasked with constructing a rectangular box with a square base, an open top, and a volume of 184 in3. Determine what the dimensions of the box should be to minimize the surface area of the box. What is the minimum surface area? Keep your answer in radical form and omit units.
Answer:
7.17 by 7.17 by 3.58
Step-by-step explanation:
Since the rectangular box is square based, the total surface area is expressed as;
S = x²+2xh+2xh (the top is opened)
S = x² + 4xh ..... 1
x is the side length of the square
h is the height of the box
Also the volume V = x²h
Given V = 184
184 = x²h
h = 184/x² .... 2
Substitute 2 into 1;
S = x² + 4xh
S = x² + 4x(184/x²)
S = x² + 4(184/x)
S = x² + 736/x
Since we need a dimension that will minimize the surface area of the box then, dS/dx = 0
dS/dx = 2x -736/x²
0 = 2x -736/x²
multiply through by x²
0 = 2x³- 736
2x³ = 736
x³ = 736/2
x³ = 368
x = ∛368
x= 7.17 in
Since V = x²h
184 = 7.17²h
h = 184/7.17²
h = 184/51.4089
h = 3.58 in
Hence the dimensions of the box should be to minimize the surface area of the box are 7.17 by 7.17 by 3.58
a bathtub is draining at a consistent rate. after 2 minutes, it holds 28 gallons of water. three minutes later, it holds 7 gallons of water. write an equation that represents the number y of gallons of water in the tub after x minutes.
Answer:
y = 42 - 6 x
Step-by-step explanation:The slope-intercept formula is:
y = m x + b,
or: y = b - m x, since the rate is negative.
For the 1st formula we have: y = 30 and x = 2
For the 2nd formula: y = 12 and x = 5 ( because: 5 = 2 + 3, or : 3 minutes later, which can be confusing )
30 = b - 2 m
12 = b - 5 m
--------------------
b = 30 + 2 m
12 = 30 + 2 m - 5 m
3 m = 18
m = 18 : 3 = 6
b = 30 + 2 * 6 = 30 + 12 = 42
y = 42 - 6 x
The length of the rectangle is 3 times its width.
The perimeter of the rectangle is 16 inches.
.
Which of the following is a reasonable length for this rectangle?
Answer:
Since length is three times, hence it is 6 inches.
let the width be x.
then, length= 3x
perimeter= 16 inches.
perimeter of a rectangle = 2( L+B)
2(3x+x)=16.
3x+x= 16÷2
4x= 8
x= 2
since length=3x
hence, 3×2= 6 inches
