The complete question in the attached figure
let
r-----------> <span>the amount charged for a refill
</span><span>b ----------> the amount charged for the egg breakfast.
we know that
2r+b=8.40
3r+b=9.35
Part a) </span><span>Write a system of equations for the situation
the answer Part a) is</span>
2r+b=8.403r+b=9.35<span>
Part b) </span><span>Graph the equations in the system
</span>
using a graph tool
see the attached figure
Part c) <span>Use your graph to estimate how much each item cost.
we know that
</span><span>the point of intersection of both graphs is the solution of the system
</span>
the solution is the point (0.95,6.5)
therefore
r=0.95
b=6.5
the amount charged for a refill is $0.95 the amount charged for the egg breakfast is $6.5
Answer:
There is a 40% probability that she will choose a green marble
Step-by-step explanation:
2/5=0.4
0.4 as a percentage is 40%
The correct answer to this problem is
C=3
Y=3
12 boys : 26 students
divide by 2 and you get
6 : 13
this can’t be divided anymore so the ratio in simplest form is 6:13
There were 4 friends you divide 20 by 5 and you get 4 friends
