Answer:
x - 4 = 0 and x - 2 = 0
Step-by-step explanation:
Total money before purchasing = $30
Cost of each song = $1.20
Solution:
According to the table,
No. of songs Amount
2 27.60
3 26.40
4 25.20
Difference between amount she have after bought 3 songs to 2 songs:
27.60 – 26.40 = 1.20
Difference between amount she have after bought 4 songs to 3 songs:
26.40 – 25.20 = 1.20
So, the cost of each song = $1.20
Amount of money she had after purchasing one song = $27.60 + $1.20
= $28.80
Tasha initially had before purchasing songs = $28.80 + $1.20
= $30
Hence Tasha initially had $30 before purchasing songs and the cost of each song was $1.20.
Answer:
Step-by-step explanation:
AD and EH are parallel lines
Angle CBD = Angle CFH = x (corresponding angles)
x + 2x = 180 (angles on a straight line)
3x = 180
x = 60
Angle GFH = 120
Angle CBD = 60
Answer:
Step-by-step explanation:
A=P(1+r/n)^nt
A=56057(1+((0.095)/4))^(4)2.5
A=$138922.0053
Answer:
Step-by-step explanation:
115+94+107+2x=360 degree(sum of interior angles of four angles is always 360 degree)
316+2x=360
2x=360-316
x=44/2
x=22 degree
