Answer:

First subtract 7 from each side of the equation

Step-by-step explanation:

2x+7 = 13

First subtract 7 from each side of the equation

2x+7 -7 = 13-7

2x = 6

Next divide each side by 2

2x/2 = 6/2

x=3

Answer:

X=3

The answer should have a positive sign.

Step-by-step explanation:

<em>First, you subtract by 7 both sides of equation.</em>

<em>2x+7-7=13-7</em>

<em>Simplify.</em>

<em>13-7=6</em>

<em>2x=6</em>

<em>Then, divide by 2 both sides of equation.</em>

<em>2x/2=6/2</em>

<em>Simplify, to find the answer.</em>

<em>6/2=3</em>

<em>X=3 is the correct answer.</em>

If EFH = (5x + 1)°, HFG = 62°, and EFG = (18x + 11)°, find EFH
olga55 [171]

Given:

Consider the below figure attached with this question.

∠EFH = (5x + 1)°, ∠HFG = 62°, and ∠EFG = (18x + 11)°

To find:

The measure of ∠EFH.

Solution:

From the figure it is clear that ∠EFG is divide in two parts ∠EFH and ∠HFG. So,

\angle EFG=\angle EFH+\angle HFG

18x+11=(5x+1)+(62)

18x+11=5x+63

Isolate variable terms.

18x-5x=63-11

13x=52

Divide both sides by 13.

x=\dfrac{52}{13}

x=4

The value of x is 4.

\angle EFH=(5x+1)^\circ

\angle EFH=(5(4)+1)^\circ

\angle EFH=(20+1)^\circ

\angle EFH=21^\circ

Therefore, the measure of ∠EFH is 21°.

One solution to a quadratic equation is x= -5/3 What is true about any remaining solutions?
miv72 [106K]

Answer:

There is exactly one more real solution or there is exactly one more complex solution

Step-by-step explanation:

A quadratic equation is a polynomial of degree two

What this means is that a polynomial has two answers.

Now, from the question, we have an answer already which is a real root

Then the other answer which we do not have can take the form of two answers

It can either be a complex root or other wise be a real root

So the answer to this question is that ;

There is exactly one more real solution or there is exactly one more complex solution
