First you add 8x to both sides because a positive is the opposite to a negative and it’s cancels out

8-2x = -8x+14
+8x +8x

8+6x = 14

Next you subtract 8 to both sides

8+6x = 14
-8 -8

6x = 6

Last you divided 6 so x can be by itself

6x = 6
/6 /6

The answer is x=1

Hello there!

8 - 2x = -8x + 14

Let's start by subtracting 8 to both sides

8 - 2x - 8 = -8x + 14 - 8

-2x = -8x + 6

Let's add 8x to both sides

-2x + 8x = -8x + 6 +8x

6x = 6

Divide both sides by 6

6x/6 = 6/6

x = 1

The correct answer is option D

I hope this helps!

What is the width of Averi's area model? (See picture)

shepuryov [24]

Answer:

Width = x² + 5x - 4

Step-by-step explanation:

By the definition of an area model,

Area = Width × greatest common factor

Since, Area = 4x² + 20x - 16

And greatest common factor = 4

4x² + 20x - 16 = 4(Width)

By dividing both the sides of the equation by 4,

$\frac{4x^2+20x-16}{4}=\frac{4(\text{Width})}{4}$

x² + 5x - 4 = Width

Therefore, width = (x² + 5x - 4) will be he answer.

If 2 apple and 5 bananas cost 4.20 dollars and 3 apples and 4 bananas coke 4.So dollars what is the price of a apple and banana

e-lub [12.9K]

Answer:

An apple costs $0.45 and a banana costs $0.66.

Step-by-step explanation:

This question is solved by a system of equations.

I am going to say that:

An apple costs x.

A banana costs y.

2 apple and 5 bananas cost 4.20 dollars

This means that:

$2x + 5y = 4.2$

So

$2x = 4.2 - 5y$

$x = 2.1 - 2.5y$

3 apples and 4 bananas cost 4.

This means that:

$3x + 4y = 4$

Since $x = 2.1 - 2.5y$

$3(2.1 - 2.5y) + 4y = 4$

$6.3 - 7.5y + 4y = 4$

$3.5y = 2.3$

$y = \frac{2.3}{3.5}$

$y = 0.66$

Then:

$x = 2.1 - 2.5(0.66) = 0.45$

An apple costs $0.45 and a banana costs $0.66.

Please solve the question below 88

RideAnS [48]

Answer:

7361.56 yards

Step-by-step explanation:

Height of the tower = 906 yards

Mauricio's height = 2 yards

Angle of elevation = $7^{o}$

Let the distance between Mauricio and the base of the tower be represented by x.

The difference between the height of tower and Mauricio's height = 906 - 2

= 904 yards

So that applying the appropriate trigonometric function, we have;

Tan θ = $\frac{opposite}{adjacent}$

Tan $7^{o}$ = $\frac{904}{x}$

0.1228 = $\frac{904}{x}$

x = $\frac{904}{0.1228}$

= 7361.5635

x = 7361.56 yards

The distance between Mauricio and the base of the tower is 7361.56 yards.
