Answer:

Step-by-step explanation:

2)  

x + 14 \frac{13}{25}  =  -0.87

x + \frac{363}{25} = - \frac{87}{100}

x + \frac{1452}{100} = - \frac{87}{100}

x  = - \frac{87}{100} - \frac{1452}{100}

x = - \frac{1539}{100}

3)

x -8 \frac{5}{6} = 1.5

x - \frac{53}{6} = \frac{9}{6}

x =  \frac{9}{6} + \frac{53}{6}

x = \frac{62}{6}

x = \frac{31}{3}

4)

x - \frac{7}{12} = - 7 \frac{7}{16}

x - \frac{28}{48} = - \frac{119}{16}

x = - \frac{357}{48} + \frac{28}{48}

x = - \frac{329}{48}

5)

\frac{8}{9} - x = 6 \frac{1}{15}

\frac{8}{9}  = \frac{91}{15} + x

\frac{40}{45} - \frac{273}{45} = x

- \frac{233}{45} = x

x = - \frac{233}{45}

6)

-33.754 - x = 28.05

-33.754  - 28.05 = x

- 61.804 = x

x = - 61.804

Which of the following is a factor of 2xy + 8y − 8x − 32?
melamori03 [73]

We are given

2xy+8y-8x-32

We can write it as

=2y*x+2y*4-8*x-8*4

we can see that 2y is in first two terms

and -8 is in last two terms

so, we can factor it out

=2y(x+4)-8(x+4)

now, we can see that x+4 is common in both terms

so, we can factor it out

=(x+4)(2y-8)

we can see that

x+4 is one of factor of terms

so, option-B..........Answer

A.) Write an exponential expression: choose a prime number between 2 and 10 to be the base, and an even between 0 and 10, to be
Slav-nsk [51]

Answer:

e_3^{4} will be the exponential expression.

Step-by-step explanation:

We have to choose a number between 0 ad 10 and has to be odd to be base say 3

And even number between 0 ad 10 to be exponent  say 4.

So the exponential expression will be : e_3^{4}

According to the information given above expression is the required expression.

What is the coefficient b makes the equation true for any real number x -3 (2x-3) + 5x = bx + 9
QveST [7]

Answer:

b = 0

Step-by-step explanation:

x -3 (2x-3) + 5x = bx + 9

x - 6x +9 + 5x = bx + 9

-9 -9

x - 6x + 5x = bx

-5x + 5x = bx

0 = bx

b/x 0/x

b = 0

Andre says 10x + 6 and 5x + 11 are equivalent because they both equal 16 when x is 1. Do you agree with Andre?​
Serga [27]

Answer:

No, They are not equivalent

Step-by-step explanation:

The two expressions are only said to be equivalent if they are the same regardless of whatever value the variable(s) is.

The variable in this question is x.

To prove this, we equate both expressions:

10x + 6 = 5x + 11

10x - 5x = 11 - 6\\\\\\5x = 5\\\\\\x = 1

This shows that they have the same value ONLY when x is 1.

This is why Andre says that they are equivalent, but they are not.
