.50(150)+30=$105
8(32)+12 = $268
5x + 14 = 26
subtract 14 on both sides
5x = 26 - 14
5x = 12
Divide 5 on both sides
x = 12/5
x = 2.4
That's only to the nearest tenth. To make it to the hundreth, just add another 0 at the end. It doesn't change the value of it.
x = 2.40 is your final answer.
70 because you would divide 150.8 by 2 and it gives you 75.4 but you have to round it and do v=4/3×3.14×70^3
