x=2
Step-by-step explanation:
x-5=5x-13
5x-x=-5+13
4x=8
x=8/4
x=2
Answer:
the solution is x<-2
.
Step-by-step explanation:
each time you multiply both sides with a negative number or if you divide both sides by a negative number, you need to "turn" the greater/less sign, so, transform
<
into
>
and vice versa
if you flip the sides of the equation, you also need to "turn" the greater/less sign.
In a circle, the measure of an inscribed angle is half the measure of the intercepted arc ⇒ x = 40/2 = 20°
