Diego va a la confitería tiene 150 pesos y cada dulce vale 15 pesos, pero compró un refresco de $ 25 ¿por cuántos dulces tiene? tengo que usar esta ecuacion y=mx+b

8

Step-by-step explanation:

y = mx + b

150 = 15x + 25

15x + 25 = 150

15x + 25 = 150 (el 25 se cancela)

       -25    -25

15x = 125 (divide cada lado por 15) (y el 15 se cancela dejando la x sola)

15       15

x = 8.3 (pero como necesitas un numero completo lo redondeas al 10 mas sercano que seria 8)

x = 8

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
