Answer:
The cost of one burger is $2.95
The cost of one fry is $1.45
Step-by-step explanation:
Let
x----> the cost of one burger
y---> the cost of one fry
we know that
----> equation A
----> equation B
Using a graphing tool
Remember that the solution of the system of equations is the intersection point both graphs
The intersection point is (2.95,1.45)
see the attached figure
therefore
The cost of one burger is $2.95
The cost of one fry is $1.45
Answer:
x = -2, y = -2
Step-by-step explanation:
Your goal is to try and cancel out a variable. I want to get rid of y so i subtracted the first equation from the second one.
After that I solve for x and got x=-2.
I used x=-2 and plugged it back into either of the equation to solve for y.

Answer:
0.4
Step-by-step explanation:
Given
60 % wear neither ring nor a necklace
20 % wear a ring
30 % wear necklace
This question can be Solved by using Venn diagram
If one person is choosen randomly among the given student the probability that this student is wearing a ring or necklace is
The sum of probabilty is equal to 1 because it completes the set
Therefore the required probabilty is 0.4
