Answer:

$x=-2$

Step-by-step explanation:

So we have the equation:

$6-4x=7x-9x+10$

First, combine like terms on the right:

$6-4x=-2x+10$

Add 4x to both sides. The left cancels:

$6=2x+10$

Subtract 10 from both sides. The right cancels:

$-4=2x$

Divide both sides by 2:

$x=-2$

So, the value of x is -2.

And we're done!

Step-by-step explanation:

$6 - 4x = 7x - 9x + 10 \\ 6 - 4x = - 2x + 10 \\ 6 - 10 = - 2x + 4x \\ - 4 = 2x \\ x = \frac{ - 4}{2} \\ x = - 2$

hope it helped you:)

What statement is true?

givi [52]

Answer:

$\frac{18}{32}>\frac{16}{32}$

Step-by-step explanation:

We need to find which statements are true.

Solution to find the same we will solve each statement and will conclude the same.

1. $\frac{14}{21}>\frac{17}{24}$

Now On solving we get;

$\frac{14}{21} = 0.66$

$\frac{17}{24}=0.70$

So we can see that 0.70 > 0.66

Hence The given statement is False.

2. $\frac{18}{32}>\frac{16}{32}$

Now On solving we get;

$\frac{18}{32}=0.5625$

$\frac{16}{32}= 0.5$

So we can see that 0.5625 > 0.5

Hence The given statement is True.

3. $\frac{20}{15}$

Now On solving we get;

$\frac{20}{15} = 1.33$

$\frac{28}{23}=1.2$

So we can see that 1.33 > 1.2

Hence The given statement is False.

4. $\frac{29}{35}$

Now On solving we get;

$\frac{29}{35}= 0.82$

$\frac{20}{30}= 0.66$

So we can see that 0.82 > 0.66

Hence The given statement is False.

Does anyone know this?

scoundrel [369]

Answer:

B is correct

Step-by-step explanation:

In order to simplify a square root, look at the number inside the square root. See its factors. For this problem, 100*2=200. The square root of 100 is 10, which you would take outside of the square root. This leaves 2 inside the square root, which cannot be further simplified.

Can someone help me with this:

Answer:

F (-8, -1)

Step-by-step explanation:

We can solve the system using substitution.

From the second equation

x-6y= -2

x= -2 + 6y

This value of x substitute into 1st equation

-4x+5y=27

-4(-2+6y)+5y=27

8-24y+5y =27

- 19y = 19

y= -1

x= -2 + 6y, y= - 1

x= -2 +6(-1)= -8

x= - 8

x= -8, y= -1

(-8, -1)
