Considerando la definición de una ecuación, la edad actual de Claudia es 60 años.
Una ecuación es la igualdad existente entre dos expresiones algebraicas conectadas a través del signo de igualdad en la que figuran uno o varios valores desconocidos, llamadas incógnitas, además de ciertos datos conocidos.
Los miembros de una ecuación son cada una de las expresiones que aparecen a ambos lados del signo igual.
En este caso, "dentro de 10 años Claudia tendrá el doble de la edad que tenía hace 25 años," puede ser expresado mediante una ecuación, donde consideras que "x" es la incógnita, que representa la edad actual de Claudia.
Teniendo en cuenta que el doble de un número se calcula multiplicando el número por 2, entonces:
Dentro de 10 años: x +10 Edad que tenía Claudia hace 25 años: x-25El doble de la edad que tenía Claudia hace 25 años: 2×(x-25)=2(x-25)Entonces, la ecuación queda expresada como:
x+10=2(x-25)
Resolviendo:
x+10=2x-50
10 + 50= 2x - x
60= x
Finalmente, la edad actual de Claudia es 60 años.

What is 3 3/7 in it's simplest form?
Answer:
Mixed Number: 3 3/7
Improper Fraction: 24/7
Step-by-step explanation:
3 3/7 is already in its simplest form. However, we can also turn it into an improper fraction.
3 3/7 --> 24/7
You get that by multiplying 3 and 7 (21) and then adding the numerator (3) to get 24. The denominator (7) remains the same. All in all, it becomes: 24/7

The sum of three numbers is 164. The second number is 3 more than twice the first number, and the third number is four times the first number. What are the three numbers
Answer:
23, 49, and 92
Step-by-step explanation:
three numbers x, y, z
x+y+z=164
y=2x+3
z=4x
we have three equations and two of them are in terms of x so we can solve for x first by plugging in the two equations to our first equation
x+2x+3+4x=164
7x+3=164
7x=161
x=23
then find y
y=2(23)+3=46+3=49
then find z
z=4(23)=92
Equation a line into slope-intercept form simplifying fractions 5x+6y=42?
Answer:
5x+6y = 42
Step-by-step explanation:
solve for y
6y = -5x + 42
y = (-5/6)x +42/6
y =(-5/6)x + 7 where -5/6=slope and 7=y intercept

If the condition like the symbol which on the graph
(1,4) and (6,-1) in slope intercept form
Answer:
[tex]Y = -X+5[/tex]
Step-by-step explanation:
To find the slope you need to do [tex]m = \frac{y2-y1}{x2-x1}[/tex]
Using that formula you will get [tex]m = -1[/tex]
Now you need to use the slope -1 and a given point (1,4) to substitute for x1 and y1 in point slope form
[tex]y-4 = -1*(x-1)[/tex]
now you need to solve for y
and you get....
[tex]y= -x + 5[/tex]

The perimeter of a rectangle is 56 centimeters. If the length of the rectangle is four centimeters less
than three times its width, what are the dimensions of the rectangle?
Answer:
Let the length be x and the width be y, then
2x + 2y = 56
x + y = 28 . . . (1)
x = 4 + 3y . . . (2)
Putting (2) into (1) gives
4 + 3y + y = 28
4y = 28 - 4 = 24
y = 24/4 = 6
x = 4 + 3(6) = 4 + 18 = 22
Therefore, length is 22 inches and width is 6 inches.
Write the equation of equation of the line parallel to 5x - 2y = 10 that goes through the point (-3, 6).
Can someone pls help me with this,ill give you brainliest,help asap pls
Answer:
y=5/2x+13.5
Step-by-step explanation:
5x-2y=10
-2y=-5x+10
y= 5/2x-5
y-6=5/2(x+3)
y-6=5/2x+ 7.5
y=5/2x+13.5
Answer:
Step-by-step explanation:
First you must isolate y in the given equation
5x - 2y = 10 Subtract 5x from both sides
-2y = -5x + 10 Divide both sides by - 2
y = -5/-2 x + 10 / -2
y = 2.5 x - 5 The new equation has a slope of 2.5
x = - 2
y = 6
y = 2.5x + b
6 = 2.5*-2 + b
6 = -5 + b Add 5 to both sides
6+ 5 = b
b = 11
Answer: y = 2.5x + 11
