Which of the following is an inequality sentence?

ziro4ka [17]

Answer:

$C. x$

Step-by-step explanation:

Option A $[x+5=20]$ tells us that: When we add 5 to a variable x, we get 20. As it has a unique value for x and is completely equal to it(i.e. 15), It is an equality.

Option B $[x=5]$ tells us that: A variable x equals to 5. Hence, as x is unique for 5 and is wholly equal to it, it's an equality too.
Option C $[x$ tells us that: A variable x isn't 5 but lesser than it. As we cannot equate it to 5, nor we are given the nature of the variable x, it is an Inequality.
Option D $[x+5]$ is an expression; It can't be called an equation or an inequality unless we relate it with another expression.

forsale [732]

Hello!

$\bf Answer:$

The probability that the can will be either tomato sauce or beans is $\bf \frac{2}{5}$ .

___________________________________________________

$\bf Explanation:$

To find the probability of he possible outcomes, we must add them together and find the least common denominator.

$\frac{12}{150} + \frac{48}{150} = \frac{60}{150}$

Divide the numerator and the denominator by 30:

$\frac{60}{150} = \frac{2}{5}$
