Number of nickels plus number of dimes equals total number of coins
so
n + d = 40
then they tell us that "there are seven times as many dimes as there are nickels"
this translates to
d = 7n
we then plug that into our first equation
and get
n + 7n = 40
then we solve for n
add like terms
8n = 40
then divide both sides by 8
n = 40/8 = 5
therefore Jimmy has 5 nickels

Answer:
I believe it to be C
Step-by-step explanation:
Answer:
C ≈ 14.18
Step-by-step explanation:
<u><em>Question Given:</em></u>
A circle has an area of 16mm². Find it's circumference.
<u><em>Formula:</em></u>
C = 2√πA
<u><em>Solve:</em></u>
C = 2√πA
C = 2√(3.14 × 16)
C = 2√50.24
C = 14.1760361173
C ≈ 14.18
<em>Hence, Circumference is approximately 14.18.</em>
