Answer:
Y=−4y/v +4x/v
Step-by-step explanation:
Divide each term in by v and simplify.
Initial amount: 27,500
Growth
Value of car change 28% each year
First, organize your variables:
Let x= the number of small packages and y=the number of large packages. C= the cost of sending the packages.
Set up your equation:
2.10x+3.90y=C
Substitute 1 and 5 for x and y since that's how many packages Diane wants to mail, and then solve for C
2.10(1)+3.90(5)=C
2.10+19.50=C
21.60=C
It will cost Diane $21.60
Answer:
The cost of the tile for the kitchen is $1,680
Step-by-step explanation:
step 1
we know that
The scale drawing is 
The dimensions of the kitchen in the blueprint are
L=3(1/4)=3/4 in
W=5(1/4)=5/4 in
step 2
Find the actual dimensions of the kitchen
Divide the dimensions of the kitchen in the blueprint by the scale drawing
L=(3/4)/(1/16)=12 ft
W=(5/4)/(1/16)=20 ft
The area is equal to
A=(12)(20)=240 ft²
step 3
Find the cost of the tile for the kitchen
7(240)=$1,680
