Step-by-step explanation:
5x-4=-3-x
5x+x=4+(-3)
6x=1
x=1/6
So right now you see that you have x and y intercept right? Then plug those intercepts in equation that you have and solve for z. Which means z=5(1)(1) will be 5, 5(4)(1) will be 20, and 5(1)(2) will be 10. So, overall you have 5, 20, 10.
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
81, if you mean 9 Squared.
3 Divided by 4 is .75
0.75 divided by four is 1/2
1/3 divided bt 4 is 1/12
3/32 + 1/12 is 17/96 (that is in simplest form)
Therefore
17/96
