William put $100 in a bank account last year. Now he has 1/12 more money in the account. Which expressions represent how much money William has in his bank account now? Choose all answers that are correct. a.100-(1/12*100) b.100+(1/12*100) c.100+(13/12*100) d.13/12*100

Answers

well he put 100 dollars in his account

he then added 1/12 more money
so the amount of money he has is 1 and 1/12 of 100 dolars  1 and 1/12 is equal to 12/12+1/12=13/12
so b. [100+(1/12*100)] makes sense and d.[13/12*100] makes sense
I think its b and d because b : 100 add half a hundred. thats right.
d : 1 and a half of 100. thats right too. hope this helped!

Write a rule for the linear function in the table (1)(3),(2)(2),(3)(1),(4)(0)

Answers

y= -x + 4
I just did this one. Look at the steps I. The other one.
Here, f(x) = {(1,3), (2,2), (3,1), (4,0)}
So, rule for this function is {x+n, y-n}

Where, n = number of steps, & x, y are the initial values of the function which is 1 & 3 respectively

Hope it Helped

Solve by the linear combination method (with or without multiplication) 2x+3y= -17, 5x+2y = -4

Answers

2x+3y= -17 
5x+2y= -4
You must cancel either the x or y out to solve so i'm going to cancel the x. 
-5(2x+3y= -17)
2(5x+2y= -4)
This simplifies to: 
-15x -15y=85
15x+4y= -8
The -15x and 15x cancel out leaving you: 
-15y=85 
4y= -8
You add them top numbers by the bottom and get: 
-11y=77
Then divide by -11 to get y by its self.
y= -7
Now that you know what y is just plug it in to either original problem. I will use the second one. 
5x + 2(-7) = -4
5x -14 = -4
5x = 10 
x = 2
So the answer is (2,-7) or x=2 and y=-7

Answer: (2,-7) or x=2 and y=-7

How many meters are in 1000 millimeters? 1 10 100 10000

Answers

1000 millimeters = 1 meter

1 millimeter equals 0.001 meters, so we can multiply the meters by 1000.

0.001 × 1000 = 1

Therefore, 1 meter is in 1000 millimeters.

The conversion of 1000 millimeters to meters is: 1 meter

How to carry out unit conversion?

There are different methods of unit conversion such as:

gram to kilogram

centimeter to meter

liters to centiliters

Newtons to kilonewtons

Now, we want to find out how many meters are in 1000 millimeters.

We know that:

1 millimeter = 0.001

Thus:

1000 millimeter = 1000 * 0.001/1

= 1 m
