Answer:
Line n slope is 9/5
Step-by-step explanation:
This one is simple, parallel lines have the same slope.
Answer: 4/7
This is a fraction
---------------------------------------------------
The two points are (x1,y1) = (2,3) and (x2,y2) = (9,7)
Which breaks down to these four facts
x1=2
y1=3
x2=9
y2=7
Plug those values into the slope formula below and simplify
m = (y2 - y1)/(x2 - x1)
m = (7 - 3)/(9 - 2)
m = 4/7
The slope is 4/7
Side Note: slope = rise/run = 4/7 so rise = 4 and run = 7. Meaning that each time we go up 4, we also go to the right 7
Because it go to google docs of middle school of math?
Answer:
She started with $6.00.
Step-by-step explanation:
1. This problem is meant to have you work backwards from the information given. Firstly, it is important to write all the expenses and earnings she had to her weekly earnings.
Starting Amount = ?
- $0.45 (candy bar)
- $2.50 (pen)
+ $.200 (mom)
End Total = $5.05
2. With this information, this next step will be much easier. With this process, you can now use inverse operations to undo the last few equations.
Firstly, $2.00 given by her mom will be subtracted from $5.05.
Secondly, with our new total of $3.05, $2.50 from purchasing the pen will be added to this amount. This leaves you with $5.55.
Lastly, the $0.45 cents she spent with the candy bar will be added to the $5.55.
This leaves the starting amount to $6.00.
3. She started with $6.00
It should be half antifreeze and then half water because you have to mix together
