Por un pantalón y unos zapatos he pagado 126€. Si el precio del pantalón aumentara en un 14%,entonves sería el 75% del precio de los zapatos. ¿Cuánto pagué por cada uno?

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

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
