Answer:
2x+1
Step-by-step explanation:
(3x-5)+(x+2)+(2x+6)=6x+3
6x+3/3=2x+1
Answer:
15
Step-by-step explanation:
2/3 of 30 is 20, so 1/2 of 30 is 15
Answer:
R1620
Step-by-step explanation:
1620 ×1=1620
1620×2=3240
1620×3=4860
1620×4=6480
1620×5=8100
1a. 3^1 / 3^2 = 3^1-2 = 3^-1 = 1/3^1 = 1/3.
2b. 4^2 / 4^4 = 4^2-4 = 4^-2 = 1/4^2.
3c. 6^3/6^5 = 6^3-5 = 6^-2 = 1/6^2.
4d. 3^-5 • 3^2 = 3^-10 = 1/3^10.
I believe for the last question its asking only to rewrite exponent as a positive exponent similar to the first question.
