Part 1. x/1.6=3 (the slash is a fraction bar)
Part 2. x= 4.8
Answer:
i'd say about 4.0
Step-by-step explanation: looked it up
The equation is already in slope - intercept form y=mx+b, where m = slope, so m=4
The slope is 4
You can see that you're constantly subtracting 8 to get the next number. So, we have
So, as you can see, to get the n-th term we must subtract (n-1) times 8 from the original number.
Lets say cost of cheeseburgers is x and cost of medium shake is y
so first fast food joint gives 2x+3y=8.98----------1
and nother one gives 7x+2y=15.45-----------------------2
multiply eq1 with 2
and multiply 3 to eq3
4x+6y=17.96
21x+6y=46.35
subtract both eq
-17x= - 28.39
cheese burger cost x=1.67 $ put x in eq1
medium shake cost y=1.88$
