According to this, then:

6x = 2*sqrt(c)*x

6 = 2*sqrt(c)

3 = sqrt(c)

c = 3^2 = 9

Hope this helps!

3+p/2=6 How do I solve this?

Diano4ka-milaya [45]

$\boxed{\underline{\bf \: ANSWER}}$

$\sf\frac { 3 + p } { 2 } = 6 \\$

Multiply both sides by 2.

$\sf \: 3+p=6\times 2$

Multiply 6 and 2 to get 12.

$\sf \: 3+p=12$

Subtract 3 from both sides.

$\sf \: p=12-3$

Subtract 3 from 12 to get 9.

$\boxed{\bf \: p=9}$

Hope it helps.

Translate then Solve for the variable:

Sergeu [11.5K]

The linear equation will be 2x + 10 = 5(x - 6). Then the value of the variable x will be 23.33.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Translate then Solve for the variable:

The sum of two times a number and 10 is five times the difference between a number and six.

Let the number be x.

Then the equation will be

2x + 10 = 5(x - 6)

Then the value of x will be

2x + 10 = 5x - 60

5x - 2x = 60 + 10

3x = 70

x = 23.33
