What you have to find is LCM(least common multiple in order to find the lcm all you have to do is list all the multiples and find their common multiple.
<span>We write the equation in the standard form which is:
ax^2 + bx + c = 0
(x + 15)(x) = 100
x^2 + 15x - 100 = 0
(x + 20) (x-5) = 0
The solutions are
x = -20 and x = 5
Therefore, the correct answer is option B. </span><span>The solution x = 5 should be kept, but x = –20 is unreasonable.</span><span>

Answer:
26.67%, or if asked to round, 27%.
Step-by-step explanation:
30 treats total
8 given away
8/30 are gone
8/30 = x/100 Set up the percentage equation.
30x = 800 Cross-multiply.
30x/30 = 800/30 Divide each side by 30 to isolate x.
x = 26.67% or 27%
X - 18 < or = 20.
x < or = 38.
Hope it helps!
Answer:
14.91g/ ml
Step-by-step explanation:
Answer:
Step-by-step explanation:
Weight of honey= (703.55g - 345.8g)
= 357.75g
But
Density= mass/ volume
Mass of honey= 357.75g
Volume of honey=24ml
If we substitute the values, we have
Density=(357.75g/24ml)
=14.91g/ ml
Hence, the density honey in g/ml is =14.91g/ ml
