Solve for x: 3-(2x-5)<-4(x+2)
trapecia [35]
3-(2x-5)=-4(x+2)

We simplify the equation to the form, which is simple to understand
3-(2x-5)=-4(x+2)

Remove unnecessary parentheses
3-2x+5=-4*(x+2)

Reorder the terms in parentheses
3-2x+5=+(-4x-8)

Remove unnecessary parentheses
+3-2x+5=-4x-8

We move all terms containing x to the left and all other terms to the right.
-2x+4x=-8-3-5

We simplify left and right side of the equation.
+2x=-16

We divide both sides of the equation by 2 to get x.
x=-8

Find the radius of a circle whose circumference is 31.4 centimeters. Approximate Π as 3.14.
AnnyKZ [126]
Circumference is Diameter * 3.14

so D * 3.14 = 31.4

31.4 / 3.14 = 10 so the diameter is 10.

the radius is half of the diameter so radius = 5 centimeters.
