Hello!
Explanation:
Distributive property: → 
First do expand.

Then you subtract by 4 from both sides of an equation.

Simplify by equation.

Next, subtract by 2x from both sides of an equation.

Simplify.

You can also divide by 2 from both sides of an equation.

Finally, simplify by equation and dividing into the groups.

Answer: →

Hello there.
<span>Which equation has solution x = -3?

Answer:

Step-by-step explanation:
<u>1) Find the radius</u>
We can do this by using the distance equation with the centre (7,1) and the given point (-1,-5):
where the two points are
and 
Plug in the points (7,1) and (-1,-5)

Therefore, the radius of the circle is 10 units.
<u>2) Plug the data into the equation of a circle</u>
Equation of a circle (when not centred at the origin):
where the centre is
and r is the radius
Plug in the centre (7,1) as (h,k)

Plug in the radius 10

I hope this helps!
No, because 2 / 2 is not 3/4
Y is 85% of 60
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 85% * 60
Converting percent to decimal:
p = 85%/100 = 0.85
Y = 0.85 * 60
Y = 51
