adam still has 23/45 of his original collection
Hey there! I'm happy to help!
Since we are using graphs, we will do not need to algebraically solve this system of equations.
When you graph a system of equations, the solution is always the point at which the two lines intersect.
Here is our system of equations graphed. We see that the lines intersect at about (1 1/3, 2 1/3). Therefore, the correct answer is C. x=1 1/3, y=2 1/3
Have a wonderful day! :D
So... hmmm if you check the first picture below, for 2)
we could use the proportions of those small, medium and large similar triangles like

now.. for 3) will be the second picture below
Answer:
I believe the answer is 0.703.
To solve you divide the numerator by the denominator.
1 chicken meal = $5
9 chicken meals = 9($5)= $45
-
1 burger meal = $6
15 burger meals = 15($6) = $90
-
Total amount = $90+$45 = $135
-
Percent spent on chicken meals = [$40 ÷ $135] x 100
= 0.296 x 100
= 29.6% or approximately 30%
