Answer:
we are finding the least common multiple
the least common multiple of 2and3 is 6
Step-by-step explanation:
Plug y=2x+1 into <span>x+2y=17, we have:
x+ 2(2x+1)= 17
</span>⇒ x+ 2*2x+ 2*1= 17 (distributive property)
⇒ x+ 4x+ 2= 17
⇒ 5x= 17-2
⇒ 5x= 15
⇒ x= 15/5
⇒ x= 3
<span>
y= 2x+1= 2*3+1= 7
Final answer: x= 3, y= 7~</span>
It can be used on this one 10x=3
It would cost $38.40 because if you do $1.60 times 24 you get 38.4
Answer:
Step-by-step explanation:
a) The half-life equation is given by:
b) Using the decay equation we have:
we need to find t when 
Therefore, it will take 4820 years to decay to half the original amount.
I hope it helps you!
