kendra is 3 times her duahters age plus 7myears kendra is 49 years old. write an equation to find her duaters age
natima [27]

Answer:

Kendra's daughter is 14 years old.

Step-by-step explanation:

If I'm reading this correctly, it says "plus 7 <em>more</em> years." I'm writing my equation based off that phrase being true.

Set up equation:

Variable x = daughter's age

x × 3 + 7 = Kendra

x × 3 + 7 = 49

3x + 7 = 49

3x = 42

x = 14

Check your work:

14 × 3 + 7 = 49

42 + 7 = 49

49 = 49

Correct!

Lee y contesta santiago quiere comer la mitad de un pastel y alba quiere un tercio del mismo pastel para repartirlo bien reducen
Thepotemich [5.8K]

Answer:

El pastel se debe dividir en 6 partes iguales, de las cuales Santiago debe tomar 3 y Alba debe tomar 2.

Step-by-step explanation:

Dado que Santiago quiere comer la mitad de un pastel y Alba quiere un tercio del mismo pastel, para repartirlo bien se deben reducir las fracciones a su común denominador. Así, para determinar en cuántas partes iguales deben dividir el pastel y cuántas partes debe tomar cada uno se deben realizar los siguientes cálculos:

Santiago = 1/2

Alba = 1/3

2 x 3 = 6

Santiago = 1/2 = 3/6

Alba = 1/3 = 2/6

Por lo tanto, el pastel se debe dividir en 6 partes iguales, de las cuales Santiago debe tomar 3 y Alba debe tomar 2.
