Answer:

x=7

Step-by-step explanation:

\frac{2}{5}x+\frac{1}{3}=\frac{1}{3}x+\frac{4}{5}

Subtract \frac{1}{3} from both sides:

\frac{2}{5}x+\frac{1}{3}-\frac{1}{3}=\frac{1}{3}x+\frac{4}{5}-\frac{1}{3}

\frac{2}{5} x=\frac{1}{3}x+\frac{12}{15}-\frac{5}{15}

\frac{2}{5}x=\frac{1}{3}x+\frac{7}{15}

Subtract \frac{1}{3} x from both sides:

\frac{2}{5}x-\frac{1}{3}x=\frac{1}{3}x+\frac{7}{15}-\frac{1}{3}x

\frac{6}{15}x-\frac{5}{15}x=\frac{7}{15}

\frac{1}{15}x=\frac{7}{15}

Multiply both sides by 15:

15\times \frac{1}{15}x=\frac{7\times 15}{15}

x=\frac{105}{15}

x=7

!! Need help with the problem in the photo. !!
lianna [129]

Answer:

B 3x-2y=10

Step-by-step explanation:

This is correct because when solved it has the same slope as line <em>k.</em>

The slope of <em>k</em> is 3/2.

3x-2y=10

first subtract 3x from both sides

-2y=-3x+10

next divide both sides by -2

y=3/2x-5

this shows that the slope 3/2 is the same as line <em>k</em>

The square of a number is 12 less than 7 times the number. What is the number?
hjlf

<u><em>Answer:</em></u>

The number is either 3 or 4


<u><em>Explanation:</em></u>

Assume that the number we are looking for is x

The square of the number would be x²

7 times the number would be 7x


<u>We are given that:</u>

square of the number (x²) is 12 less than 7 times the number (7x)


<u>Translating this into an equation, we would have:</u>

x² = 7x - 12


<u>Rearranging the quadratic equation:</u>

x² - 7x + 12 = 0


<u>Now, we factor the equation:</u>

(x-4)(x-3) = 0


<u>This means that:</u>

either x-4 = 0 ..................> x = 4

or x-3 = 0 ........................> x = 3


<u>Let's check if any of the solutions is an extrovert:</u>

For x = 3 .............> (3)² = 7(3) - 12 .........> 9 = 21 - 12 .......> 9 = 9 .......> not extrovert

For x = 4 .............> (4)² = 7(4) - 12 .........> 16 = 28 - 12 .....> 16 = 16 ....> not extrovert


Since we have no restrictions on the number, therefore, both solutions would be accepted


Hope this helps :)
