Answer:

$5.95

Step-by-step explanation:

Given :

Let containers = c ;Gallon of gas = g

2c + 8g = 38.06 - - - (1)

c + 3g = 15.76 - - - - (2)

From (2) :

c = 15.76 - 3g

2(15.76 - 3g) + 8g = 38.06

31.52 - 6g + 8g = 38.06

2g = 6.54

g = 6.54 / 2

g = 3.27

Recall :

c = 15.76 - 3g

c = 15.76 - 3(3.27)

c = 5.95

Answer:

x < -16, none of the solution sets are correct for the given equation.

Step-by-step explanation:

-1/4x > 4, multiply both sides by -4, don't forget when you multiply or divide by a negative you have to flip the sign.

x < -16

none of the solution sets are correct for the given equation.

Select the correct answer from each drop-down menu.

lbvjy [14]

Answer: a) additive inverse (addition)

b) multiplicative inverse (division)

<u>Step-by-step explanation:</u>

Step 2: 6 is being added to both sides

Step 4: (3/4) is being divided from both sides

It is difficult to know what options are provided in the drop-down menu without seeing them. If I was to complete a proof and justify each step, then the following justifications would be used:

Step 2: Addition Property of Equality

Step 4: Division Property of Equality

3 3/6 =<br> + 1 2/3 =<br><br><br><br> Add. Write the sum in lowest term

defon

3 3/6 is equal to 21/6
1 2/3 is equal to 5/3
Both 3 and 6 go into 6 so the denominator is 6
Now multiply 5 by 2 because 3 goes into 6 twice.
10/6
You don't need to change 21/6 because the denominator is already 6
So now you need to add them
21/6+ 10/6= 31/6
Which is also 5 1/6
So the overall answer is 5 1/6

How do I solve it <br>?????

Shalnov [3]

Answer:

Step-by-step explanation:

$METHOD\ \#1\\\\\text{Put b = 3 to each equation and check equality:}\\\\A.\ 3-24b=75\\L_s=3-24(3)=3-72=-69\\R_s=75\\L_s\neq R_s\\\\B.\ 65+9b=38\\L_s=65+9(3)=65+27=92\\R_s=38\\L_s\neq R_s\\\\C.\ -2b+30=24\\L_s=-2(3)+30=-6+30=24\\R_s=24\\L_s=R_s\\\\D.\ 102b-21=-55\\L_s=102(3)-21=306-21=285\\R_s=-55\\L_s\neq R_s$

$METHOD\ \#2:\\\\\text{Solve each equation:}\\\\A.\\3-24b=75\qquad\text{subtract 3 from both sides}\\-24b=72\qquad\text{divide both sides by (-24)}\\b=-3\neq3\\\\B.\\65+9b=38\qquad\text{subtract 65 from both sides}\\9b=-27\qquad\text{divide both sides by 9}\\b=-3\neq3\\\\C.\\-2b+30=24\qquad\text{subtract 30 from both sides}\\-2b=-6\qquad\text{divide both sides by (-2)}\\b=3\\\\D.\\102b-21=-55\qquad\text{add 21 to both sides}\\102b=-34\qquad\text{divide both sides by 102}\\b=-\frac{1}{3}$
