X+y=31 So, x=31-y
x+3y=85

31-y+3y=85
31+2y=85
2y=54
y=27
x+3×27=85
x+81=85
x=4

Ellie practices piano 2/3 h per day, several days each week. She practiced piano 32/23 hours during the summer.

butalik [34]

Let us assume that the number of days she practiced the piano to be "d"

Since she practiced 2/3 hours a day, the total number of hours would be: 2/3*d

Now we are given the total number of hours during summer that she practiced be be equal to 32/23

So we equate 2/3 * d to 32/23 to find d

2/3*d = 32/23

d = (32/23)/ (2/3)

d = (32/23) * (3/2)

d = 48/23 hours

The equation that can be used to find the number of days that she practiced piano during the summer is 2/3*d = 32/23

[2.4–(0.3–3.21)÷2+0.44÷(−2)]÷ 2/5=

[4.8:2-(-2.91):2-0.44:2]:2/5=

=[(4.8+2.91-0.44):2]*5/2=

=[(7.71-0.44):2]*5/2=

=(7.27:2)*5/2=(7.27*5):(2*2)=
