Alejandro rounded the number 76.518 to 76.5. Jiro rounded the same number to 76.52. Who is correct? Explain your reasoning

sergeinik [125]

Alejandro is correct because you do not need to add another number to 76.518, as Jiro did, but you need to round it to the nearest tenth.

Glad I could help, and good luck!

harina [27]

Answer:

x = 5, y = 7, z = 12

Step-by-step explanation:

<u>Let the numbers be x, y and z</u>

x + y + z = 24
2y = z + 2
z = x + y

<u>Solving by substitution:</u>

x + y + z = z + z = 24
2z = 24
z = 12

2y = z + 2
2y = 12 + 2
2y = 14
y = 7

z = x + y
x = z - y
x = 12 - 7 = 5

<u>The answer:</u>

x = 5, y = 7, z = 12
