Ann and Joes father donated 3$ for for every lap they sam in a swim a thin. Ann swam 21 laps and joe swam 15 laps. Use he distri
Anna35 [415]

To solve this problem, we must remember that the distributive property allows us to get rid of parentheses by multiplying the coefficient by each of the terms in parentheses. In this case, our coefficient is 3, because that is the number of dollars Ann and Joe's father will donate per lap. This means that we must multiply this by the total number of laps that they swam, which can be found by adding together their individual number of laps, 21 + 15.

This makes our expression: 3(21 + 15)

Using the distributive property, we can multiply both numbers in the parentheses by 3 to simplify our expression, as shown below:

3(21) + 3(15)

Now, we must multiply these numbers together to simplify.

63 + 45

When we add these two numbers together, we get 108.

Therefore, your final answer is that their father donated $108.

Hope this helps!

#7-9 please help with an explanation,, will mark brainliest
Mandarinka [93]

Answers:

<h2>7. 12</h2><h2>8. -√18</h2><h2>9. √220</h2>

Step-by-step explanation:

To find out which is greater, we must eliminate the radical symbol.

#7

\sqrt{88} = 9.38083151965

9.4 < 12

#8

-\sqrt{18} = -4.24264068712

-4.2 > -6

#9

\sqrt{220} = 14.8323969742

14.5 < 14.8

I'm always happy to help :)

Identify the inequalities A, B, and C for which the given ordered pair is a solution: (0,0)<br>​
professor190 [17]

Answer:

Options (A) and (C)

Step-by-step explanation:

A). The given inequality is,

    x + y ≤ 2

    Solution area of the inequality is the shaded area below the line.

    Since (0, 0) lies in the shaded region, ordered pair will be a solution of this inequality.

B). For the inequality y ≤ \frac{3}{2}x-1

   Since, (0, 0) doesn't lie in the shaded region of this inequality, ordered pair will not be a solution of the inequality.

C). y > -\frac{1}{3}x-2

    In this graph (0, 0) lies in the shaded region of the inequality therefore, it will be a solution of the given inequality.

Therefore, Options (A) and (C) are the correct options.
