Terryn has 25 one-dollar bills and wants to give an even amount to each of his two children. How many bills do each of Terryn's
aleksley [76]

Answer:

Number of one-dollar bills each child gets: 12 dollars

Dollars left over: 1 dollar

Step-by-step explanation:

25/2=12.5

so round down to 12 cause 13(2) is 26 and you only have 25.

so 12(2)=24.

Each kid will get 12 dollars and there will be 1 dollar left over.

Using the slope and the y intercept, graph the line represented by the following equation.
PtichkaEL [24]
Beforehand let me apologize for my sloppy handwriting. I'm a lefty, so please deal with me. . Anyway, the equation you listed didn't really have a x, because a linear equation is y= mx+b, and anything with x is the slope. But I did see y and a number on one side, so I'm like maybe I can get these two alone. So here's what I did:

2y + 4=0
-4 -4 I subtracted 4 on both sides. Why because you would want "y" alone.
Next,
2y= -4
Now to get "y" alone you want to divide on both sides.
2y= -4/ 2
y= -2
Now you're probably thinking "how do you graph it? There's no "x" in the equation." Well, you just graph it. Since the answer is y= -2, you go to the y axis, look for -2, and place a line to indicate that is the equation. And to make it clear, remember y is the y-intercept.

I really do hope this helps you, if not message me. I'll be happy to help, and again I'm sorry for my handwriting!
