You have $-\frac{x}{2} \leq 1$ , isolating 'x' we have

<span> $-\frac{x}{2} \leq 1$
</span> $-x \leq 2$

Dividing both sides by -1 will flip the sign,
<span> $x \geq -2$ </span>

Does the point (5, 10) satisfy the inequality y>x+5

No, because if you plug in 10 for y and 5 for x then solve the inequality says 10>10

Jerome will also order t-shirt for the volunteers he will both adults and child sized t-shirt adults t-shirt are $5;and child t-

Daniel [21]

<h3><u>The two inequalities are:</u></h3>

$a\geq 200\\\\5a + 2.50c\leq 1500$

<h3><u>Solution:</u></h3>

Let "a" be the number of adult sized t shirts

Let "c" be the number of child sized t shirts

Given that,

Each Adult sized t shirts = $ 5

Each child sized t shirts = $ 2.50

<h3><u>Jerome need at least 200 adults t-shirt</u></h3>

Therefore,

$a\geq 200$

Here, we used "greater than or equal to" symbol, since he needs atleast 200 adult t-shirts

<h3><u>Jerome will spend no more than $1500 on t-shirt</u></h3>

Therefore,

$5a + 2.50c\leq 1500$

Here we used, "less than or equal to" symbol, since he will not spend more than 1500

Thus the two inequalities are found

What is the missing numerator? blank over five plus eighteen over twenty equals thirty over twenty 8 5 3 2

Oliga [24]

Given:

$\dfrac{?}{5}+\dfrac{18}{20}=\dfrac{30}{20}$

To find:

The missing value.

Solution:

Let x be the missing value.

We have,

$\dfrac{x}{5}+\dfrac{18}{20}=\dfrac{30}{20}$

$\dfrac{x}{5}+\dfrac{9}{10}=\dfrac{3}{2}$

Subtract $\dfrac{9}{10}$ from both sides.

$\dfrac{x}{5}=\dfrac{3}{2}-\dfrac{9}{10}$

$\dfrac{x}{5}=\dfrac{15-9}{10}$

$\dfrac{x}{5}=\dfrac{6}{10}$

$\dfrac{x}{5}=\dfrac{3}{5}$

Multiplying both sides by 5, we get

$x=3$

So, the missing value is 3.

Therefore, the correct option is C.
