Answer:

Let's solve for f.

4

r

+

8

f

=

5

g

Step 1: Multiply both sides by fr.

4f+8r=

5fr

g

Step 2: Multiply both sides by g.

4fg+8gr=5fr

Step 3: Add -5fr to both sides.

4fg+8gr+−5fr=5fr+−5fr

4fg−5fr+8gr=0

Step 4: Add -8gr to both sides.

4fg−5fr+8gr+−8gr=0+−8gr

4fg−5fr=−8gr

Step 5: Factor out variable f.

f(4g−5r)=−8gr

Step 6: Divide both sides by 4g-5r.

f(4g−5r)

4g−5r

=

−8gr

4g−5r

f=

−8gr

4g−5r

Answer:

f=−8gr4g−5r

At most, Alana can spend $40 on carnival tickets. Ride tickets cost $4 each, and food tickets cost $2 each. Alana buys at least
pogonyaev

Answer:

The maximum number of ride tickets is 4

Step-by-step explanation:

r = number of ride tickets

f = number of food tickets

r + f ≥ 16

4r + 2f ≤ 40

Using these as equations

f = 16  -r

Using this in the second equation

4r+ 2 (16 -r) = 40

4r +32 -2r = 40

2r +32 = 40

2r = 8

r = 4

The maximum number of ride tickets is 4
