Answer:
x=12
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
Divide C values/T values that will tell if it is constant or not and that is the reason.
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
The answer is 4.51 and what needs to be added to 4.5 is a .01
