Answer:
13
Step-by-step explanation:
25 x 2 = 50. 10% of 70 equals 7. 50 + 7 = 57. 70 - 57 = 13.
Cards given to her friend brad + cards sold online = cards givin
25+25=50
Amount of cards + cards givin = amount left
70-50=20
10% of 20=2
20-2=18
Tasha has 18 left
Hope this helps
24x + 30x = 3x + 24 + 4
54x=3x+24+4
54x=3x+28
54x-3x=28
51x=28
X=28/51
sin xy / x = 0
thay x = 0 và y = 3 vào sin xy / x ta có:
sin (0*3) / 0 = sin (0) = 0
