16. LCD: 48 because 1/4= 12/48, 1/12=4/48, 11/16= 33/48 and they all share 48 as the denominator

17.  LCD: 168 because 5/56= 15/168, 7/24= 49/168, 7/12= 98/168, 5/42= 20/168

18. LCD: 30 because 2/1= 60/30, 1/5= 6/30, 1/10= 3/30, 5/6= 25/30

Line AB passes through A(-3, 0) and B(-6, 5). What is the equation of the line that passes through the origin and is parallel to
amid [387]

parallel means "same slope (m)"

m = \frac{y2 - y1}{x2 - x1} = \frac{0 - 5}{-3 - (-6)} = \frac{-5}{-3 + 6} = \frac{-5}{3}

Now, input the point (0, 0) and the slope (\frac{-5}{3}) into the Point-Slope formula:

y - y₁ = m(x - x₁)

y - 0 = \frac{-5}{3}(x - 0)

    y = \frac{-5}{3}x

 3y = -5x    <em>multiplied both sides by 3</em>

 0   = -5x - 3y  <em>subtracted 3y from both sides</em>

Answer: C

Round to the nearest gram
earnstyle [38]

Alright, so after a half-life, half of the previous number would be left. So basically,

180 g ← 0 half lives

90 g ← 1 half life

45 g ← 2 half lives

22.5 g ← 3 half lives

11.25 g ← 4 half lives


Therefore, the answer is 11.25 grams
