Responder:
Pantalón = 50 €
Zapatos = 76 €
Explicación paso a paso:
Total pagado por pantalón y zapatos = 126
Sea el precio del pantalón = p; zapatos = s
p + s = 126
1,14 p = 0,75 s
p = 0,75 s / 1,14
0,75 s / 1,14 + s = 126
(0,75 s + 1,14 s) / 1,14 = 126
0,75 s + 1,14 s = 143,64
1,89 s = 143,64
s = 143,64 / 1,89
s = 76
p + s = 126
P = 126 - s
P = 126 - 76
p = 50
Answer:
20
Step-by-step explanation:
You can start by evaluating the expressions inside the parenthesis:

Step-by-step explanation:
The equation of a horizontal line is
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (- 3, 8 ) with y- coordinate of 8, thus
y = 8 ← equation of horizontal line
Answer:
10 cm.
In order to better understand this question, I will attach an allusive image to the question.
Keep in mind that in this case the base of the triangle is equal to the radius of the base of the cone since the triangle rotates on its own axis, therefore the measurement of the base corresponds to 10 cm, therefore the radius measures 10 cm.
