Mathematics
1 answer:
____ [38]3 years ago
3 0

ANSWER: 5

X = 2

Equation: 3x-1 =

________________

Since the equation says that “X” is 2, we will replace the X with 2 within the equation. Now you see here, since there's no symbol with the 3 and “X”, it means they are multiplying ( Or as seens as : 3(2) - 1 =

Then you will get 6 - 1

Which is obviously 5.

In this equation they are saying that X is 2 and that you should replace the letter X with 2 in the equation.

If you have any other questions, please ask. I'm willing to help.

What is the value of x? 3x−8=8x+4/2 Enter your answer in the box
krek1111 [17]

For this case we must find the value of "x" of the following expression:

3x-8 = \frac {8x + 4} {2}

Multiplying by 2 on both sides of the equation:

2 (3x-8) = 8x + 4\\6x-16 = 8x + 4

Subtracting 8x from both sides of the equation:

6x-8x-16 = 4\\-2x-16 = 4

Adding 16 to both sides:

-2x = 4 + 16\\-2x = 20

Dividing between -2 on both sides:

x = \frac {20} {- 2}\\x = -10

Answer:

x = -10

Ype the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.
rewona [7]

Answer:

4/8 or 1/2

Step-by-step explanation:

Convert all size to x/8

1/4=2/8 and 1/2=4/8

Multiply size of beaker by how many there are filled

1/8 * 2= 2/8

2/8*7= 14/8

4/8*3 =12/8

then add all of them together = 28/8

convert 4 liters to 32/8

Subtract 32/8 - 28/8 = 4/8
