I think it’s c sorry if it’s wrong
Answer:
the answer is 5.1%
Step-by-step explanation:
first you divide 37 by 39 to get .94871795
next you would subtract 1 by that number and you get
.05128205 which can be rounded to .051 or 5.1%
1)x+1) has positive slope, it is only A or B
2) For f(x)=4 we have x≥1, so this graph should begin with black dot.
3)So answer is B
Blue dot should be empty.
Orange dot should be black.
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
