Solve for x 0.5(5−7x)=8−(4x+6) x = ???

1 answer:

7 0

Hello!

0.5 (5 - 7x) = 8 - (4x+6)
2.5 - 3.5x = 8 - 4x + 6
2.5 - 3.5x = 2 - 4x
-3.5x + 4x = 2 - 2.5
0.5x = -0.5
X = -1

Your answer is x = -1. I hope this helps!

ASHA 777 [7]

Answer:

Step-by-step explanation:

Let x represent the amount that he paid for one hamburger.

Daniel buys lunch for his family from a food stand. He purchased one hot dog for $2.50 and 3 hamburgers. The cost of 3 hamburgers would be 3x.

If he spent a total amount of $13 on the hot dog and hamburgers, it means that

2.5 + 3x = 13

3x = 13 - 2.5 = 10.5

x = 10.5/3

x = $3.5

16r^4t-6r^3t^2+4rt^2=

DochEvi [55]

Answer:

$2rt(8r^3-3r^2t+2t)$

Step-by-step explanation:

We have been given a polynomial $16r^4t-6r^3t^2+4rt^2$ and we are supposed to simplify our polynomial.

We will use factoring to simplify our polynomial. Let us factor out the greatest common factor of all the terms.

We can see that 16, 6 and 4 has 2 as their greatest common factor.

The greatest common factor of $r^4, r^3,r$ is r.

The greatest common factor of $t, t^2, t^2$ is t.

So the greatest common factor of the terms of our expression will be $2rt$ .

Let us factor out $2rt$ from our given polynomial.

$2rt(8r^3-3r^2t+2t)$

As we can not factor our expression more, therefore, we will get $2rt(8r^3-3r^2t+2t)$ after simplifying our polynomial.

Derek says that the quotient of -2/7 divided by -2/21 is -1/3. Part A: What is the correct quotient? Part B: What mistake did De

Thepotemich [5.8K]

Answer:

The correct quotient is 3.

I think Derek has mistaken to divide $-\frac{2}{21}$ by $\frac{2}{7}$ .

Step-by-step explanation:

We have to check the quotient of $(-\frac{2}{7}) \textrm{ divided by }(-\frac{2}{21})$ .

Part A:

Now, $(-\frac{2}{7}) \textrm{ divided by }(-\frac{2}{21})$ .

= $\frac{-\frac{2}{7} }{-\frac{2}{21} } =3$

So, the correct quotient is 3.

Part B:

Derek says that the quotient is $-\frac{1}{3}$ .

So, I think Derek has mistaken to divide $-\frac{2}{21}$ by $\frac{2}{7}$ . (Answer)
