3) Add 2.82, 3.44, and 4.15. Then round it so it looks like this : #.#
4) Add 0.55, 0.15, 0.40, and 0.05 all together
5) Subtract 0.39 from 0.72.
the ratio that is equal to 10:85 is 20:170 because if you multiply both sides by two you get 20:170
28^2=784
29^2=841
784<830<841
therefore sqrt784<sqrt830<sqrt841
therefore 28<sqrt830<29
Done!
Answer:
a = 6, b = -2, c = 3
Step-by-step explanation:
6x² - 2x + 3 = 0
a = 6, b = -2, c = 3
7(12 1/3) + 8(12 1/3 + 1/4) = 3(6(12 1/3) - 9) - 8
12 1/3 = 12.33
1/4 = 0.25
7(12.33) + 8(12.33 + 0.25) = 3(6(12.33) - 9) - 8
86.31 + 8(12.58) = 3(73.98 - 9) - 8
86.31 + 100.64 = 3(64.98) - 8
186.95 = 186.94 - 8
186.95 ≠ 178.94
False. The x, when 12 1/3 does not work inside this equation
hope this helps
