Answer:
26 miles per gallon
Step-by-step explanation:
You can but 13 CDs and add it to your 27 to have 40. So no, not all of the 15 CDs you bought will fit.
Replace y with 200 ( amount of water in the tank) and solve for x:
200 = 450 -20x
Subtract 450 from both sides:
-250 = -20x
Divide both sides by-20:
X = 12.5
The answer is A. 12.5 minutes
Answer:
13 weeks; 98 dollars.
Step-by-step explanation:
Let's say x represents the number of weeks, and y the number of dollars. For Janelle, an equation to find out how much money she has is y = 20 + 6x. For April, the equation is y = 150 - 4x. Now we need to find how long it will take them to have the same amount of money, and how much that is. A new equation to figure that out is 150 - 4x = 20 + 6x. To solve, make it so the variable is only one side. Add 4x to both sides. You now get 150 = 20 + 10x. Then we continue solving. Subtract 20 from both sides to get 130 = 10x. Then divide both sides by 10 to get 13 = x. This means in thirteen weeks, they will have the same amount of money. To find out how much money they have, choose one (or both to be sure) of the equations and solve for y. For example, Janelle's equation is y = 20 + 6x. Fill in 13 for x to get y = 20 + 6(13). y = 20 + 78. y = 98. This means in 13 weeks, Janelle will have 98 dollars. To be sure, also check with April's equation. y = 150 - 4x. y = 150 - 4(13). y = 150 - 52. y = 98. Therefore, in 13 weeks, both people will have 98 dollars.
Well, the slope for each side is simple.
All you have to do to remember slope is rise over run.
So for example:
For Vertices E and F the Slope would be 3/9
For Vertices G to H the slope would be 3/9
For vertices G to F the slope would be 6/2
For vertices H to E the slope would be 6/2
What do you notice about slopes on opposite sides?
Answer:
( H to E,and G to F) Have the same slope
(And G to H and E to F.) Have the same slope.
What do you notice about slopes of adjacent lines?
adjacent means adjoining or next to. So can you figure this question out? Using the information above?
