Answer:

The solutions of 5x-10\le \:20 are (-\infty \:,\:6], so C is the correct answer.

Step-by-step explanation:

The expression 5x-10\le \:20 is an inequality. An inequality is a mathematical statement that compares two expressions using an inequality sign.

The important thing about inequalities is that there can be multiple solutions.

To find all the solutions of 5x-10\le \:20 you must:

\mathrm{Add\:}10\mathrm{\:to\:both\:sides}\\5x-10+10\le \:20+10

\mathrm{Simplify}\\5x\le \:30

\mathrm{Divide\:both\:sides\:by\:}5\\\frac{5x}{5}\le \frac{30}{5}

x\le \:6

The graph of the inequality x\le \:6 is shown below.

According with the graph the solutions are less than or equal to 6, using interval notation (-\infty \:,\:6].

The solutions of 5x-10\le \:20 are (-\infty \:,\:6], so C is the correct answer.

= 3/-12 = -1/4

Point (8,2)

b = 2 - (- 1/4)(8)

Alexandra [31]

Answer:

<h3>Therefore total amount of money that he got is = $(5+0.50x)   [ x = number of correct math]</h3>

Step-by-step explanation:

Given, Gilberto's grandfather gives him $5 for his birthday and then$0.50 for each math he answers correctly on his math exam for the year.

Let , the number of math that he answers correctly on his his math exam for the year is x

Therefore he got = $(0.50× x) =$ 0.50x for doing correct math.

Therefore total amount of money that he got is = $(5+0.50x)   [ x = number of correct math]

sukhopar [10]

Answer: The result is a lemon with a velvety peel and an intense yet mellow lemony character—whose "texture is soft and flavor is deep," says Sortun. From there, the options are manifold. In On Food and Cooking, Harold McGee suggests that a solution of 5 to 10% salt is needed to achieve a good North African–style preserved lemon.
