The answer in which you were looking for is C. 106
Answer:
2/5
Step-by-step explanation:
expressing 1 1/2 in an improper fraction:
1 1/2 = 3/2
Hence
(3/5) ÷ (1 1/2)
= (3/5) ÷ (3/2) (convert divide to multiply by flipping divisor fraction)
= (3/5) x (2/3)
= (3 x 2) / (5 x 3)
= 6/15 (divide both numerator and denominator by 3)
= 2/5
For the answer to the question above, I'll provide my solutions below.
x² + 4 = 0
<span> - 4 - 4
</span> x² = -4
x = +2i
x² - 6x + 1 = 0
x = -(-6) +/- √((-6)² - 4(1)(1))
2(1)
x = 6 +/- √(36 - 4)
2
x = <span>6 +/- √(32)
</span> 2
x = <span>6 +/- 2√(2)
</span> 2
x = 3 + √(2)
x = 3 + √(2) x = 3 - √(2)
I hope this helps.
(10 + 14 + 8 + 16 + 12 + x ) /6 = 13
(60 + x) / 6 = 13
60 + x = 13 * 6
60 + x = 78
x = 78 - 60
x = 18 <=====
