Try this solution:
1. Note, that 100 is divisible by 4, and 999 is not divisible by it, only 996. This is an arithmetic sequence.
2. a1;a2;a3;a4;...a(n) the sequence, where a1=100; a2=104; a3=108; a4=112; ... etc., and a(n)=996. n=?
3. using a formula for n-term of the sequence: a(n)=a1+d(n-1), where a(n)=996; a1=100 and d=4 (according to the condition ' is divisible by 4'). Then 100+4(n-1)=996; ⇒ 4n=900; ⇒ n=225 (including 100).
answer: 225
Answer:
yes
Step-by-step explanation:
1 cm=10mm. if 1cm=10mm what about 9cm
Answer:
45 kg = Bethan's share
105 kg = Jade's share
Step-by-step explanation:
Let 3x = Bethan's share
4x = Noah's share
7x = Jade's share
Since Noah's share was 60, then 4x = 60
x = 15
3(15) = 45 kg = Bethan's share
7(15) = 105 kg = Jade's share
