3:4:5 = 3+4+5 = 12
660/12 = 55
55*3 = 165
55*4 = 220
55*5 = 275
person 1 = 165
Person 2 = 220
person 3 = 275
Answer:
C. 2x + 12
Step-by-step explanation:
2(10) + 2(x-4)
= 20 + 2x - 8
= 2x + 20 - 8
= 2x + 12
2.32*103 = 2.39E3, or 2.39*10^3
This result is likely wrong because I first thought your 103 literally meant 103. Now it seems that you meant 10^3 (10 to the third power). So, ignore the above result and multiply again: 2.32*10^3. This is already in scientific notation.
4.2*10^4 is already in scientific notation.
4.2*10^(-2) is already in scientific notation.
5700=1.7*10^3 (answer in scientific notation)
6548000= 6.55*10^(-6) (in scientific notation)
1g = 1000mg
40,000mg = 40g
10xg=40g
X=4
Hope this helps.
