Subtract 100 from both sides
50x = 150 + 30x - 100
Simplify 150 + 30x - 100 to 30x + 50
Subtract 30x from both sides
50x - 30x = 50
Simplify 50x - 30x to 20x
20x = 50
Divide both sides by 20
x = 50/20
Simplify 50/20 to 5/2
<u>x = 5/2</u>
<em>In decimal: 2.5</em>
You can calculate the arc lenght by using this formula:
arc length = 2π*r*(A/360) , where A=angle of the arc.
So for you it would be:
arc length = 2π*4*(72/360) = 5.03
I hope that helped.
Answer:
m2 or inch2 or pulg2
Step-by-step explanation:
2(2ax-y)=3ax-4y
4ax-2y=3ax-4y
Move 3ax from the right to the left. You do so by subtracting 3ax from both sides. Once doing so, you should have:
ax-2y=-4y
Isolate ax. You do so by adding (-2y) to both sides. After doing so, you should have:
ax=-2y
To isolate y by itself, you divide everything by -2, thus, equaling y= ax/-2
