My question is what is 7+6x=3x+3+4x

Mathematics

7+6x= 3x+3+4x

7+6x= 3x+4x+3

7+6x= 7x+3

move +7x to the other side

sign changes from +7x to -7x

7+6x-7x= 7x-7x+3

7-x= 3

Move 7 to the other side.

Sign changes from +7 to -7.

7-7-x= 3-7

-x= -4

Multiply by -1

-1(-x)= -1(-4)

x= 4

answer: x= 4

If the measure of 0 is A radians and B degrees, then A=180B/pie
yKpoI14uk [10]
Yup that is correct, that is the way to convert measurements of angle from radians to degrees. because 2pi is equivalent to one revolution of a circle and in degrees is equal to 360 degrees, then simplifying it 360 / 2pi = 180 / pi.
so <span>the measure of 0 is A radians and B degrees, then A = 180 B/pi</span>

Give me a correct answer, My answer probably wrong.
Georgia [21]

Hello!

This is a problem about the general solution of a differential equation.

What we can first do here is separate the variables so that we have the same variable for each side (ex. dy with the y term and dx with the x term).

\frac{dy}{dx}=\frac{x-1}{3y^2}

3y^2dy=x-1dx

Then, we can integrate using the power rule to get rid of the differentiating terms, remember to add the constant of integration, C, to at least one side of the resulting equation.

y^3=\frac{1}{2}x^2-x+C

Then here, we just solve for y and we have our general solution.

y=\sqrt[3]{\frac{1}{2}x^2-x+C}

We can see that answer choice D has an equivalent equation, so answer choice D is the correct answer.

Hope this helps!
