Answer:

C. More than 1 solution

Step-by-step explanation:

Divide the second equation by 3.

y -x = -3

Add x.

y = x -3

This matches the first equation exactly, meaning that any solution to the first equation is also a solution to the second equation. There are an infinite number of possibilities. There is "More than 1 solution."

A single die is rolled on time. Find the probability of rollung a number greater than 5 or less than 4

suter [353]

Answer:

$\dfrac{2}{3}$

Step-by-step explanation:

A single die is rolled on time.

All possible outcomes are $1,2,3,4,5,6$ (6 in total)

Rolling a number greater than 5 or less than 4 means rolling numbers $6$ or $1,2,3$ so

All favorable outcomes are $1,2,3,6$ (4 in total)

The probability of rolling a number greater than 5 or less than 4 is

$P=\dfrac{\text{Number of all favorable outcomes }}{\text{Number of all possible outcomes}}\\ \\=\dfrac{4}{6}\\ \\=\dfrac{2}{3}$
