Answer:
x = 9
Step-by-step explanation:
Jane writes 7x
Andrew writes 5x + 18

7x = 5x + 18 ( subtract 5x from both sides )
2x = 18 ( divide both sides by 2 )
x = 9

Answer:
$93.33 per dose
Step-by-step explanation:
$1.4×10⁶/(7.5 kg) × (1 kg)/(1000 g) × (0.5 g)/(1 dose)
= (1.4×10⁶×0.5)/(7.5×10³) $/dose = 700/7.5 $/dose ≈ $93.33/dose

Converting dollars per kilogram to dollars per dose involves units conversion from kilograms to doses. We have done it in two steps, first to grams, then to doses.
A prime number is a number which is only divisible by itself and 1.
No even numbers can be primes because they are all divisible by 2.
Therefore, 14 is not a prime number.
21 ÷ 3 = 7
33 ÷ 3 = 11
That leaves 13.
13 is a prime number.
