X=25 degrees

2x+3x+x+30 = 180
6x+30 = 180
180 - 30 = 150
6x = 150
150/6 = 25
X = 25

Sophia had 64¢ until she spent 1 quarter. How much money does Sophia have now?

aleksklad [387]

Answer:

Sophia now has 39 cents.

Step-by-step explanation:

$\: \: \: 64 \: cents \\ \frac{ - 25 \: cents}{ \: \: \: 39 \: cents}$

Therefore, Sophia now has 39 cents.
