Answer:
Least 4 5/7 {-6 5/7} - | -7 1/7 {-4 4/5} | 5 5/7 X 5 5/7.
Step-by-step explanation:
In a trapazoid the diagonals are the same so therefore the two equations equal echother
3x+7=5x-11 solve for x by combining like terms
18=2x then divide to unto multiplication
9=x
9 is the value of x

Answer:
It would be 6 dollars
Step-by-step explanation:
20 percent of 30 dollars is 6 dollars.
If an item costs 30 dollars and it's on sale for 20 percent off, how much will you save? To figure this out, you need to find 20 percent of 30.
This is easy to do in your head. Think of what 10 percent would be. 10 percent of 30 would be the same as .10 x 30, or 3. So, 10 percent off is 3 dollars off.
20 percent is twice as much as 10 percent. If 10 percent off is 3 dollars, then 20 percent off would be 2 x 3 or 6.
20 percent of 30 dollars would be 6 dollars.
Answer:
Step-by-step explanation:
X = Movies | Y = Video Games
Using these variables, we can set up equations.
3x + 2y = $24 eq1
8x + 4y = $57 eq2
We have here a system of equations, where we have two or more equations with two or more different variables. We use the elimination method to solve for the variables.
Multiply eq1 by 8. Multiply eq2 by 3.
24x + 16y = $192 eq1
24x + 12y = $171 eq2
Subtract eq2 from eq1 to eliminate the x terms.
4y = 21
y = $5.25
This rental cost of one video game is $5.25
Substitute the value of y into eq1 to solve for x. This will give you the rental cost of one movie.
The rental cost of one movie is $4.50
3($4.50) + 2($5.25) = $24
8($4.50) + 4($5.25) = $57
