Solve the formula for x.<br> V=2πrx+6πr2
Anna [14]

Answer:

x=−18.849556r2+v/6.283185r

Step-by-step explanation:

Step 1: Flip the equation.

18.849556r2+6.283185rx=v

Step 2: Add -18.849556r^2 to both sides.

18.849556r2+6.283185rx+−18.849556r2=v+−18.849556r2

0r 2+6.283185rx=−18.849556r2+v

Step 3: Divide both sides by 6.283185r. 0r2+6.283185rx/

6.283185r = −18.849556r2+v/6.283185r

x=−18.849556r2+v/6.283185r

If R is the midpoint of QS, RS=2X-4, ST=4X-1, and RT=8X-43, find QS
Cloud [144]
RT = RS + ST
8x - 43 = 2x - 4 + 4x - 1
8x - 43 = 6x - 5
8x - 6x = -5 + 43
2x = 38
x = 38/2
x = 19

QS = 2RS = 2(2x-4) = 2(2*19-4) = 2*34 = 68
