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.

Yolanda bought 12 pounds of rice for $5 . How many pounds of rice did she get per dollar?
defon
<h3>Answer:  2.4 pounds per dollar</h3>

Explanation:

We can set up the ratio

12 pounds : 5 dollars

Then divide both parts of that ratio by 5 so that the "5 dollars" becomes "1 dollar"

  • 12/5 = 2.4
  • 5/5 = 1

The ratio 12 pounds : 5 dollars is equivalent to 2.4 pounds : 1 dollar

Can u plz help me look at the photo<br><br> PLZ NO LINKS
djyliett [7]

Answer:

0.07

Step-by-step explanation:

The hundredths place is the place between the tenths and thousandths place. For example, the digit in the tenths place in 0.073 is 7.

To round to the nearest hundredth, we look to the digit right of the hundredth digit, 7. We notice that the digit in the thousandths place is 3. When rounding, if a number is 4 or less, we change that digit to a 0, along with the digits beyond it. If a number is 5 or more, we bump up the digit to the next number. Since 3 is less than 4, we change 0.073 to 0.07.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

nignag [31]

Answer:

41

Step-by-step explanation:

Given Expression:

(4 x 9 - 21) \ 3+6^2

Multiply 4 and 9 to get 36.

36 - 21 / 3 + 6^2

Subtract 21 from 36 to get 15.

15/3 + 6^2

Divide 15 by 3 to get 5.

5+6^2

Calculate 6 to the power of 2 and get 36.

5+36

Add 5 and 36 to get 41.
