8090kg-4854kg=decrease in kg ----- find the difference
3236=decrease in kg
3236kg/8090kg=percent decrease ----- decrease/original amount
0.4= percent decrease ------ percent decrease in decimal form
0.4*100=percent decrease ------ multiply by 100 to get percent form
40% decrease
-7.5 / -2.5 = 3

Answer: b
Step-by-step explanation:
Answer:
c= ab + d/ a
Step-by-step explanation:
Let's solve for c.
a(c-b)=d
Step 1: Add ab to both sides.
-ab + ac + ab = d+ ab
ac = ab + d
Step 2: Divide both sides by a.
ac / a = ab + d / a
c = ab + d/ a
Answer:
c= ab + d/ a

So we have 2 variables here: tacos and orders of nachos.
When we translate the paragraphs into equation:

Now, in this situation we can make use the elimination method by converting 3n to -27n.

Add both equations:

So we find that one taco costs $2.75.
We can plug this into any of the first two equations to find n:

So one order of nachos cost $1.40.
