4a + 6b= 10 2a - 4b =12 what does 12a=
mixer [17]
4a + 6b = 10
2a - 4b = 12...multiply by -2
----------------
4a + 6b = 10
-4a + 8b = - 24 (result of multiplying by -2)
------------------add
14b = - 14
b = -14/14
b = -1

2a - 4b = 12
2a - 4(-1) = 12
2a + 4 = 12
2a = 12 - 4
2a = 8
a = 8/2
a = 4

so 12a = 12(4) = 48 <==

A specific cars engine has a capacity of 5.1 Lof oil. How many quarts of oil does the engine have?
mr Goodwill [35]

<u>ANSWER: </u>

The engine have 5.39 qt approximately.

<u>SOLUTION: </u>

Given, a specific cars engine has a capacity of 5.1 L of oil.  

We need to find how many quarts of oil does the engine have?

Number of quarts of oil is product of number of liters of oil and the number of quarts per liter.

We know that, one liter of liquid contains 1.056 quarts approximately.

Number of quarts of oil = number of liters of oil x number of quarts per liter.

Number of quarts of oil = 5.1 liters x 1.056 quarts.

Number of quarts of oil = 5.1 x 1.056  

Number of quarts of oil = 5.389 qt.

Hence, the engine have 5.39 qt approximately

7,220 kids drink zero.

14,060 kids drink one

5,700 kids drink two

(multiply the total amount of kids by the percent (convert percent to decimal))

When added together, you get 26,980.

24. C

5,700 kids drink two

2,660 kids drink three

1,140 kids drink four

7,220 kids drink five or more

When added together, you get 16,720 kids.

Next set up a proportion.

38,000 total 30 total kids
------------------ = --------------------
16,720 kids x

For 38,000 to get to 30, you have to divide 38,000 by 1,266.67.

This means that you also have to divide 16,720 by 1,266.67.

This gets you 13.

Which set describes the domain of p(h)? {h| 0 ≤ h ≤ 40} {h| 0 ≤ h ≤ 60} {p(h)| 0 ≤ p(h) ≤ 1,400} {p(h)| 0 ≤ p(h) ≤ 1,800}
Vera_Pavlovna [14]

The set {h| 0 ≤ h ≤ 60} describe the domain of p(h).

According to the statement

We have given that the brenton gets paid $20 per hour for the first 40 hours he works in a week. For any hours above that, he is paid overtime at $30 per hour.

and we have to find that the those set which describes the domain of p(h).

So,for this purpose

In this case, the domain represents the set of hours he is permitted to work

From the question, we understand that he cannot work more than 60 hours

This means that, the least number of hours to work is 0, and the highest is 60

So, the domain is 0 to 60

When represented properly, the domain of P(h) is (b)  {h| 0 ≤ h ≤ 60}.

So, The set {h| 0 ≤ h ≤ 60} describe the domain of p(h).

Question:

Brenton’s weekly pay, P(h) , in dollars, is a function of the number of hours he works, h. He gets paid $20 per hour for the first 40 hours he works in a week. For any hours above that, he is paid overtime at $30 per hour. He is not permitted to work more than 60 hours in a week. Which set describes the domain of P(h)? {h| 0 ≤ h ≤ 40} {h| 0 ≤ h ≤ 60} {P(h)| 0 ≤ P(h) ≤ 1,400} {P(h)| 0 ≤ P(h) ≤ 1,800
