D=dimes
q=quarters
if she has 12 coins then
12-d=q she has 12-d quarters
we dont know how much money she has unless we know d.
she could have 12 dimes and 0 quarters or 11 dimes and 1 quarter etc. we need more information to solve.
Hamburger 1.80lbs sausage is 1.90lbs
1.80+ 1.80+ 1.90=$5.50
Answer:
N = 10
Step-by-step explanation:
Normally the coordinate system goes:
x axis (horizontal)
y axis (vertical)
Here, we have:
Horizontal axis as "M", and
Vertical axis as "N"
We want to know what N will be when M equals 50.
So, we look at the x-axis and go to M equals 50.
Then we move up until the "trend line". The intersection.
If we move directly left to vertical axis (N variable), we see that it is at the point:
N = 10
So,
When M = 50, N = 10
4(r)^x=y
4(r)^(1)=2
r=1/2
y=4*(1/2)^x
