8 x 1 = 8
8 x 1/2 = 4
8+4 =12
therefore, 8 x 1 1/2 = 12
It would be 2u3+4u2-2u-4u2-8u+4= 2u3-10u+4
Your answer is D)16. To find the average, add up all the numbers and divivde by the number of numbers there is
Answer: 30
Step-by-step explanation:
3+4+3=10 400/10=40 so each has 40 so math has 120 120*25=3000 for physics is 4*40 so 160 160*20=3200 9800-3000-3200=3600 3*40=120 3600/120=30
Since 5=15/3
5^x = (15/3)^x = 15^x / 3^3
