Answer:
<em>x < 2</em>
Step-by-step explanation:
-12x - 0.4 > 0.2(36.5x + 80) - 55
-12x - 0.4 > 7.3x + 16 - 55
-19.3x > -38.6
x < 2
Answer: 729
Step-by-step explanation:
Move items with negative exponents from numerator to denominator or vice versa and change sign of exponent. Factorize composite numbers, say 10^3 = 2^3 × 5^3 and 81 = 3^4. Combine factors with same base, adding exponents. Cancel factors appearing in both numerator and denominator, subtracting exponents.
5^-3×6^-5×81×4/(3^-7×10^-3)
= 3^7×10^3×81×4/(5^3×6^5)
= 3^7×2^3×5^3×3^4×2^2/(5^3×2^5×3^5)
= 2^5×3^11×5^3/(2^5×3^5×5^3)
= 3^6
= 729
Answer:
10^4
Step-by-step explanation:
Ten to the power of 4

Expand the left side:
3x-18 = 10x + 3
Subtract 3x from each side:
-18 = 7x + 3
Subtract 3 from each side:
-21 = 7x
Divide each side by 7 :
<u>-3 = x</u>
39.5 all you have to do is divide 158 and 4 which gives you 39.5
