<h2><u>solución</u></h2>
deja que los números sean x, and x + 2
sabemos que su suma es igual a 100, entonces
por lo tanto, el primer número es 49
y el segundo número es x + 2 = 49 + 2 = 51 (también es el mayor entre los dos números)
entonces suma de dígitos de mayor número = 5 + 1 = 6
Respuesta correcta de la pregunta anterior = 6
Answer:
C
Step-by-step explanation:
Convert them all to the form y = mx + c
1)
4x + 3y = 15
3y = -4x + 15
y = -4/3 x + 5
2)
3x - 4y = -8
-4y = -3x - 8
4y = 3x + 8
y = 3/4x + 2
3)
y + 1 = 4/3(x - 6)
y + 1 = 4/3x - 8
y = 4/3x - 9
4)
y = 3/4x - 5
The profit is 5rs because 25-20=5rs
Simplifying
3x + 4 = 7 + -2x
Reorder the terms:
4 + 3x = 7 + -2x
Solving
4 + 3x = 7 + -2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2x' to each side of the equation.
4 + 3x + 2x = 7 + -2x + 2x
Combine like terms: 3x + 2x = 5x
4 + 5x = 7 + -2x + 2x
Combine like terms: -2x + 2x = 0
4 + 5x = 7 + 0
4 + 5x = 7
Add '-4' to each side of the equation.
4 + -4 + 5x = 7 + -4
Combine like terms: 4 + -4 = 0
0 + 5x = 7 + -4
5x = 7 + -4
Combine like terms: 7 + -4 = 3
5x = 3
Divide each side by '5'.
x = 0.6
Answer: x = 0.6
