Here is the complete question (in attachment).

The least price is for Water Spring brand and the greatest price is of Clear Mountain brand.

Step-by-step explanation:

To find the unit price we have to divide the full price with the whole of the quantity.

From least to greatest unit prices are arranged below.

Water Springs $=\frac{19.99}{48}=0.416\$$
Nature's River $=\frac{20.35}{48}=0.423\$$

Forest Air $=\frac{10.49}{24}=0.437\$$
Iceland Springs $=\frac{5.49}{12}=0.457\$$

Clear Mountain $=\frac{11.99}{24}=0.499\$$

In ascending order the number are.

$0.416 < 0.423< 0.437< 0.457< 0.499$

So the least price is for Water Spring brand,and the greatest price is for Clear Mountain brand.

in a school 60% of the total number of student are boys. if the number of girl is 500, how many student are there in the class

Andreas93 [3]

Answer:

x=1250 students

Step-by-step explanation:

x= total amount of students

boys=60% of x

so left is 40% of girls given number is 500

so x=total number of boys+girls

X = (60/100)*X+500

X - (60/100)*X = 500

(40/100)*X = 500

X = (500*100)/40

x=1,250 students

Here is an inequality: -2x>10

jek_recluse [69]

Answer:

The right solution is " $x>-5$ ".

Step-by-step explanation:

The given inequality is:

⇒ $-2x>10$

By solving the above expression, we get

⇒ $x >-\frac{10}{2}$

⇒ $x>-5$

Thus the above is the correct answer.

Which are correct representations of the inequality –3(2x – 5) < 5(2 – x)? Select two options.

avanturin [10]

The correct simplified inequality is - 6x + 15 < 10 - 5x and the number line representation is "an open circle is at 5 and a bold line starts at 5 and is pointing to the right".

The given inequality is -3(2x - 5) < 5(2 - x)

We need to simplify the inequality.

<h3>What is inequality?</h3>

In mathematics, inequality is a statement of an order relationship greater than, greater than or equal to, less than, or less than or equal to between two numbers or algebraic expressions.

Consider LHS and simplify -3(2x - 5) = -3(2x)-5(-3)

⇒ -3(2x - 5) = - 6x + 15 [∵(-)(-) = (+)]

Consider RHS and simplify 5(2 - x) = 5(2) + 5(-x)

⇒5(2 - x) = 10 - 5x [∵(+)(-) = (-)]

Now, - 6x + 15 < 10 - 5x

By subtracting 15 from both sides, we get

- 6x < -5 - 5x

By adding 5x to both sides, we get - x < - 5

The coefficient of x is -1. So, divide both sides by -1

Then we get x > 5

Hence, the correct simplified inequality is - 6x + 15 < 10 - 5x and the number line representation is "an open circle is at 5 and a bold line starts at 5 and is pointing to the right".
