11. Liza earned some money delivering newspaper .She bought a battery for $1.95, and gave her mother $30. She bought a ring
for $7.20, and then spent half of the remaining money on a radio.
If Liza has $38.50 left, how much money did she earn delivering
newspapers?
anonh the solution set.

$116.15

Step-by-step explanation:

We first would start with the last  thing, the $38.50 Lisa has left! From reading the word problem, we can tell that she had another $38.50 she spent on a radio.She spends $7.20 (ring) + $1.95 (battery) before this and gives her mom $30.

All of these are subtractions from the initial amount:

x - 1.95 - 30.00 - 7.20 - 38.50 = 38.50

x - 77.65 = 38.50

x = $116.15

Please give brainliest! It would really help!

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
