Answer:
The equation that will determine the cost of two folders is; 3x = 2× $2.91
and the cost of the 2 folders is $1.94
Step-by-step explanation:
To solve this problem, we will follow the steps below;
Using proportion;
Let x be the cost of 2 folders
3 folders = $2.91
2 folders = x
Cross-multiply
3x = 2× $2.91
The equation that will determine the cost of two folders is
3x = 2× $2.91
We can go ahead and solve
3x = $5.82
Divide both-side of the equation by 3
= 
x = $ 1.94
The cost of 2 folders is $1.94
Answer:
8n=20+6(n-2)
Step-by-step explanation:
n is the number of GB
Plan A has no initial fee and charges 8$ per each GB
So A has an equation that is y=0+8n or just y=8n.
Plan B has 20 for the first 2 GB and $6 for each addition GB after the first 2.
So B has an equation that is y=0+20+6(n-2) assuming n is 2 are greater.
So the two equations are y=8n and y=20+6(n-2).
We want Plan A to be the same as Plan B.
So we need to solve:
8n=20+6(n-2).
Let's check our equation:
Distribute:
8n=20+6n-12
Subtract 6n on both sides:
2n=20-12
2n=8
Divide both sides by 2:
n=4
Plan A charges 8 dollars ber GB, so plan A charges 4(8)=32 dollars.
Plan B charges 20 dollars for the first 2GB and 6 dollars for each GB after so we used 4 which means we are spending 20+6(2)=20+12=32 dollars.
They are the amount so n=4 is right.

Answer:
X=36
Step-by-step explanation:
Let x be the unknown number
Three quarters of a number =3x/4
Three was added =3x/4 +3
Final
3x/4 + 3= 30
Multiply through with 4
3x+ 12=120
3x=120-12
3x=108
X=108/3
X=36
