Carlos debe estudiar para seis evaluaciones para ello distribuirá entre las seis materias 1/4 del tiempo del que dispone este fin de semana
Answer:
[tex]Tiempo = \frac{1}{24}[/tex]
Step-by-step explanation:
La pregunta está incompleta, sin embargo, una posible pregunta podría ser calcular el tiempo que Carlos dedicará a estudiar cada asignaturas.
Para hacer esto, simplemente dividimos el tiempo disponible por el número de asignaturas.
Tenemos:
[tex]Tiempo\ disponible = \frac{1}{4}[/tex]
[tex]Numero\ de\ sujetos = 6[/tex]
Solución
[tex]Tiempo = \frac{Tiempo\ disponible}{Numero\ de\ asignaturas}[/tex]
[tex]Tiempo = \frac{1}{4} / 6[/tex]
[tex]Tiempo = \frac{1}{4} * \frac{1}{6}[/tex]
[tex]Tiempo = \frac{1}{24}[/tex]
Esto significa que dedicará 1/24 de su tiempo a cada
The perimeter of a square is given as 8x+20. Write two different expressions for the perimeter. Use factoring to write one of the expressoins. Are the expressions equivalen? Explain
Answer:
P = 4(2x + 5)
P = (2x + 5)+(2x + 5)+(2x + 5)+(2x + 5)
Step-by-step explanation:
Given that:
Perimeter of square = 4 * s
Where s = side length
If perimeter, P = 8x + 20
Then,
4s = 8x + 20
Divide both sides by 4
4s / 4 = (8x + 20) / 4
s = 2x + 5
P = 4s
P = 4(2x + 5)
Or
P = 2x + 5 in 4 places
P = (2x + 5)+(2x + 5)+(2x + 5)+(2x + 5)

Andre and Elena are each saving money. Andre starts with $100 in his savings account and adds $5 per week. Elena starts with $10 in her savings account and adds $20 each week.
Answer:
6 weeks
Step-by-step explanation:
You need to write an equation for each.
For Andre, he has 100 dollars, and every week gets 5 dollars more. You add the 5 dollars, and Since you don't know how many weeks it has been, use a variable.
For Elena, she has 10 dollars, and gets 20 each week.
Now that you know that it has been 4 weeks, you can plug in 4 for the variable for weeks.
Andrew:100+5(4)=100+20+120
Elena: 10+20(4)=10+80=90
Andrew has more money in this time.
To find when they have the same amount, equal their expressions to each other. This means that they will have the same amount (because they are equalled) and you can solve to find the variable, which means the weeks that they are equal at.
Bring the like terms to each side by canceling them out. Since you have positive 10, then subtract 10 to each side. You have 5w, so subtract 5w to each side.
100+5w=10+20w
90+5w=20w
90=15w
90 divided by 15=6
w=6
How to tell the difference between multiplication and division word problems?
Answer:
Multiplication is one of the four elementary mathematical operations of arithmetic, with the other ones being addition, subtraction and division. The result of a multiplication operation is called a product. And division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication

A triangle has side lengths of 6, 8, and 9. What type of triangle is it? right obtuse equiangular acute
Answer:
acute
Step-by-step explanation:
Answer:
It is an acute triangle
Step-by-step explanation:
If it is an acute triangle, a^2 + b^2 > c^2
If it is a right triangle, a^2 + b^2 = c^2
If it is an obtuse triangle, a^2 + b^2 < c^2
If it is an equilateral triangle, a = b = c
6^2 +8^2 ? 9^2
36+64 ? 81
100 ? 81
? is >, meaning it is an acute triangle.

Find the area of the
triangle.
Answer:
472.5
Step-by-step explanation:
Answer:
Step-by-step explanation:
Base (b) = 30 yd
height (h) = 31.5 yd
Area of the triangle
= 1/2 * b * h
= 1/2 * 30* 31.5
=472.5 yd²
EXPLAIN when |−x| = x would be true.
HINT: If you are stuck, try substituting each of x = -1, x = 0, and x = 1 into the equation. Then, interpret your results.
Answer:
It's true when x = a positive number.
Step-by-step explanation:
I don't know how to explain this, so here we go.
The definition of absolute value is the distance a number is away from 0.
In other words, all numbers are now positive or 0.
If |-x| = x, it means x would have to be positive because, well, to prove that, we have to see what it couldn't be a negative number
if x was a negative number (-1), this is what we would get
|-(-1)| = -1
|1| = -1
1 = -1
That's not right!
And this happens in any negative number you do.
Because the absolute value of something cannot be negative
I cannot stress that enough
Since it is the absolute value of -x, x has to be positive, if it isn't, then there is no solution for x.
Any number greater than or equal to zero is a possible answer for the absolute value of something, but the absolute value of something cannot be a negative number
I hope this helps, let me know if you have any questions.

X + 2y = 10
3x + 4y = 8
Which point is the solution to the system of equations?
Answer:
x = -12
y = 11
Step-by-step explanation:
i used substitution and let 'x' = 10 - 2y
3(10 - 2y) + 4y = 8
30 - 6y + 4y = 8
30 -2y = 8
-2y = -22
y = 11
x + 2(11) = 10
x + 22 = 10
x = -12

what is a linear equation
Answer:
A linear equation is an algebraic equation of the form y=mx+b. Where m is the slope and b is the y-intercept. A linear equation most times is called a "linear equation of two variables," where y and x are the variables.
Step-by-step explanation:
A racing shell, which is a boat a crew team rows, moves 20 km/h in still water. During practice, the team rows 36 km against the current and 22 km with the current. Find the speed of the river current if the team rows a total of 3 hours.
Answer:
2 km/h
Step-by-step explanation:
Let x represent the speed of the river current, t₁ be the time spent rowing against the current and t₂ be the time spent rowing with the current.
Since the speed of the still water = 20 km/h.
The speed of rowing against the current = (20 - x)
The speed of rowing with the current = (20 + x)
We know that velocity = distance / time. Hence time = distance / velocity
t₁ = 36 / (20 - x)
t₂ = 22 / (20 + x)
but t₁ + t₂ = 3 hours
Therefore:
3 = 36 / (20 - x) + 22 / (20 + x)
multiply through by 400 - x²
3(400 - x²) = 36(20 + x) + 22(20 - x)
1200 - 3x² = 720 + 36x + 440 - 22x
3x² + 14x -40 = 0
This gives x = -6.7 or x = 2
x cannot be negative therefore x = 2 km/h
The speed of the river current is 2 km/h
Answer:
2km/h is correct
Step-by-step explanation:

Given 3 parallel lines intersected by 2 transversals then the parallel lines divide the transversals proportionally, that is
[tex]\frac{3x}{4}[/tex] = [tex]\frac{7.5}{2.5x}[/tex] ( cross- multiply )
7.5x² = 30 ( divide both sides by 7.5 )
x² = 4 ( take the square root of both sides )
x = [tex]\sqrt{4}[/tex] = 2
Find the marked prices of the following , given the percentage discount and the sale prices: part a: 12% discount , and the sale price $77
part b : 25% discount , and the sale price $123
Answer:
A) $87.5
B) $164
Step-by-step explanation:
A) Marked Price (Original Price)
= [tex]\frac{Sale Price}{1 -Discount}[/tex]
=[tex]\frac{77}{1-0.12}[/tex]
=87.5
B) Marked Price (Original Price)
=[tex]\frac{Sale Price}{1 -Discount}[/tex]
=[tex]\frac{123}{1-0.25}[/tex]
=164

Solve the equation
(x-3)^3-( x - 1 )^3 + 7x^2 = 7(3x - 4 )
Answer:
(x - 3)³ - (x - 1)³ + 7x² = 7(3x - 4)
=> x³ - 9x² + 27x - 27 - (x³ - 3x² + 3x - 1) + 7x² - 21x + 28 = 0
<=> -2x² + 6x + 1 + 3x² - 3x + 1 = 0
<=> x² + 3x + 2 = 0
<=> (x + 1)(x + 2) = 0
<=> x + 1 = 0 or x + 2 = 0
<=> x = -1 or x = -2
