(Equation) a - 3 = -8

Explanation: If you're asked to solve for a in the equation a - 3 = -8, you want to try to get a by itself on one side of the equation.

If we take a look at the left side of our equation, a 3 is being subtracted from a so in order to get a by itself, we must add 3 to the left side of the equation. If we add 3 to the left side of the equation, we must also add 3 to the right side of the equation to keep our equation balanced.

On the left side of the equation, our -3 and +3 cancel out and we're left with a. On the right side of the equation, -8 + 3 simplifies to -5 so a = -5.

To check our answer, we can substitute -5 back in for a in the original equation and we get (-5) - 3 = -8. (-5) - 3 can be thought of as (-5) + (-3) and you can see that this is a true statement so our answer checks.

Answer:

The dividend is 360, divisor is 6 and quotient is 60.

Step-by-step explanation:

Factors of 3= 3*1

Factors of 18= 3*2*3

Factors of 60= 3*2*2*5

Taking LCM= 3*2*2*2*3*5= 360

60 is a factor of 360

The dividend is 360

If 360 is divided by 6 we get 60 which is a multiple of 3

and 6 is a factor of 18.

Therefore the dividend is 360 divisor is 6 and quotient is 60.

Could someone explain this to me?

You must solve for p, in order to solve for p you must move all the terms to equal p, so the equation is
$2m + 2p = 16$
first move the 2m, subtract the 2m from both sides
$2m + 2p = 16 \\ - 2m \: \: \: \: \: \: \: \: - 2m$
the 2m and -2m cancel out and now your equation looks like
$2p = 16 - 2m$
now to leave p by itself you must divide by 2 on both sides as the 2 is being multiplies on the p (opposite)
$\frac{2p}{2} = \frac{16 - 2m}{2}$
now to put the answer is simplest form your answer is
$p = 8 - m$
which is the first answer choice

Answer:

The center is at ( (-1, -2) and the radius is 5.

Step-by-step explanation:

X^2 + 2X + Y^2 + 4Y = 20

Complete the square on the x and y terms.

(x + 1)^2 -1 + (y + 2)^2 - 4 = 20

(x + 1)^2 + ( y + 2)^2 = 25 Comparing this with the standard form:

(x - h)^2 + (y - k)^2 = r^2

- the center is at ( (-1, -2) and thr radius is 5.
