I’m guessing that this is for systems of equations?
n - nickels
d - dimes
These are the equations you start off with.
n = 5d-2
0.95 = 0.10d+0.05n
Substitute the top equation for n into the variable n in the bottom equation.
0.95 = 0.10d+0.05(5d-2)
Solve for d.
0.95 = 0.10d+0.25d-0.10
1.05 = 0.35d
3 = d
Substitute d into the top equation and solve for n.
n = 5(3)-2
n = 15-3
n = 12
There are 3 dimes and 12 nickels in the coin purse! Hope this helped <3
Answer:
48 in³
Step-by-step explanation:
The volume (V) of a pyramid is calculated as
V =
× area of base × height
here area of base = 24 and height = 6, so
V =
× 24 × 6 = 8 × 6 = 48 in³
Answer:3/8
Step-by-step explanation:
5/8 of the staff are male. The entire staff is represented by the fraction 8/8. Taking 5/8 from this, what we have left is
8/8-5/8 = 3/8 of the staff are female.
Answer:
Answer+Step-by-step explanation: 2019 game of the year award limited edition.
Step-by-step explanation:
This is all about carefully examining the slope. If you look carefully you will notice B curves in at the top just a little more than A so the first one is correct.
The second one is obviously not true.
The third one is disproved by the first.
The fourth one is correct as C is the peak and has little to no drop or rise.
The 5th one is correct, after spending several minutes examining it with 200%+ zoom I will tell you that it is correct B and D are the same.
I'm not 100% sure but I'm probably 95% sure that The 6th one is incorrect and A is changing height faster than D.
