Answer:

y = 9 1/3 or 8 if the first equation is 1/3x + 1/4y = 1.

Step-by-step explanation:

1/3x + 1/4y = 2

    2x - 3y = -30

Multiply the first equation by -6:

- 2x - 3/2y = -12  

Adding the last 2 equations:

-9/2 y = -42

y = -42 * -2/9

y = 9 1/3.

If the first equation is 1/3x + 1/4 y = 1

then y = -36 * -2/9

= 8.

Can the values be added or subtracted? If one value needs to be converted to another, describe the conversion.
vaieri [72.5K]
Okie, the terms are similar in that they both have inches, but they are in different forms. The first has inches to the 2nd power. This is a unit for area. The second has the units of inches to the 3rd power. This is a unit of volume. To convert from area to volume, you would need a conversion but it usually would be from a problem with certain values. Ex. Think of a cube, the 2 sides multiplied would be area and third multiplied in would be volume. If you are adding an area to a volume, you would need to know of which since you cannot change volume magically to area or area magically to volume if you do not know the details of the problem. The answer is A; I hope this helps :-)

Find the value of x. <br><br><br>A.20 <br><br>B.25 <br><br>C.18.75 <br><br>D.22.5
miss Akunina [59]

The two equations are vertical angle, which would be equal to each other.

Set the equations to equal and solve for x:

5x -10 = 3x +40

Subtract 3x from both sides:

2x -10 = 40

Add 10 to both sides:

2x = 50

Divide both sides by 2:

x = 50 / 2

x = 25

The answer is B. 25

klasskru [66]

Answer:

z-score = 2.

Step-by-step explanation:

The z-score = (x - m) / d   where x =the person's score, m = the  mean and d = the standard deviation.

So we have (87-67)/10

= 2.
