Substitute x= 3 and calculate
f(3)= 2•9+5• sqrt( 1)
f(3)= 18+5= 23
Answer:
Sue is 6 and Mary is 10
Step-by-step explanation:
let Sue's age be x then Mary is x + 4 and the sum of their ages is
x + x + 4 = 16
2x + 4 = 16 ( subtract 4 from both sides )
2x = 12 ( divide both sides by 2 )
x = 6
x + 4 = 6 + 4 = 10
then Mary is 10 and Sue is 6
300,000 / 4,000 = 75
so the weight of the blue whale is 75 times bigger then the weight of the shark
