Answer: I am pretty sure the answer is 290.55

Answer: The way you would set this up is as follows:

That's when you solve for x.

Cross multiply 260.75 * 39, and you get 10,169.25

Now divide that by 35, and you get your answer, which is $290.55

That's when you solve for x.

Cross multiply 260.75 * 39, and you get 10,169.25

Now divide that by 35, and you get your answer, which is $290.55

Water weighs about 8.34 pounds per gallon about how many ounces per gallon is the weight of the water ?

Note that 1 pound is equivalent to 16 ounces, while 1 ounce is equivalent to 0.0625 pounds.

Since the problem tackles converting pounds into ounces, we need to multiply the number of pounds to the number of ounces a pound is equivalent to, to get the total number of ounces.

Thus; 8.34 pounds * 16 ounces = 133.44 ounces. of water per gallon.

To check:

We can convert ounces back to pounds. Remember, 1 ounce is equal to 0.0625 pounds.

133.44 ounces * 0.0625 pounds = 8.34 pounds; the original weight stated in the problem.

4x+(x-y/8)=17 and 2y+x-(5y+2/4)=2 by using elimination method

Answer:

x=811/238, y=36/119. (811/238, 36/119).

Step-by-step explanation:

4x+(x-y/8)=17

2y+x-(5y+2/4)=2

-----------------------

4x+x-y/8=17

5x-y/8=17

40x-y=136

y=40x-136

------------------

2y+x-5y-2/4=2

2y-5y+x-1/2=2

-3y+x=2+1/2

-3y+x=4/2+1/2

-3y+x=5/2

-3(40x-136)+x=5/2

-120x+408+x=5/2

-119x=5/2-408

-119x=5/2-816/2

-119x=-811/2

119x=811/2

x=(811/2)/119

x=(811/2)(1/119)=811/238

y=40(811/238)-136

y=16220/119-136

y=36/119

x=811/238, y=36/119.

Which statement is true about the graphs of the two lines y = –6 and x = 1/6 ? A. The lines are perpendicular to each other because the graph of y = –6 is a horizontal line with a slope that is undefined, and the graph of x = is a vertical line with a slope of 0.

B. The lines are perpendicular to each other because the graph of y = –6 is a vertical line with a slope that is undefined, and the graph of x = is a horizontal line with a slope of 0.

C. The lines are perpendicular to each other because the graph of y = –6 is a vertical line with a slope of 0, and the graph of x = is a horizontal line with a slope that is undefined.

D. The lines are perpendicular to each other because the graph of y = –6 is a horizontal line with a slope of 0, and the graph of x = is a vertical line with a slope that is undefined.

Right answer: D

1. Lines with the form y=c, where c is a constant, like y=2, y=-3, y=21,7 ... etc are all lines parallel to the x-axis, so they are horizontal lines.

Horizontal lines have 0 inclination, so slope=0

2. Lines of the form x=c, where c is a constant, like x=5,4 , x= 7 etc are lines parallel to the y-axis, so they are vertical lines.

Vertical lines are lines with undefined slope

1. Lines with the form y=c, where c is a constant, like y=2, y=-3, y=21,7 ... etc are all lines parallel to the x-axis, so they are horizontal lines.

Horizontal lines have 0 inclination, so slope=0

2. Lines of the form x=c, where c is a constant, like x=5,4 , x= 7 etc are lines parallel to the y-axis, so they are vertical lines.
