Question #1:
Since it is unknown how much they paid for the original painting, we'll use x to represent that. 2x+1000 is equal to 55,000, so that is our equation.
2x+1000=55,000
2x=54,000
x=27,000
The Leungs originally paid $27,000 (answer choice B)

Question #12:
-4(x-11)=16
Apply the distributive property.
-4x+44=16
-4x=--28
x=7
Since x=7, let's figure out which answer choice can be possible by subsituting the x in each answer choice with 7.
Answer choice F: Does 7-11=4? No, so this answer can't be correct.
Answer choice G: Does 7-11=-4? Yes! This answer is correct.
Answer choice H: Does -28-11=16? No, so this answer can't be correct.
Answer choice I: Does -28+44=64? No, so this answer can't be correct.
It is answer choice G.

your model train has one engine and eight train cars. find the total number of ways you can arrange the train. (the engine must be first.

Answers

Answer:

40,320

Step-by-step explanation:

We are given that there are 8 train cars and 1 engine.

We will fix the first place for the engine.

So, we are left with 8 options for the next place.

Now, if we fix the second place for any one of the train cars.

We will be left with 7 options for the next place.

Going on this way until there is no place left for the train cars, we get the relation,

Total number of ways to arrange the train = 1 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1

i.e. Total number of ways to arrange the train = 1 × 8! = 8! = 40,320

Hence, the total number of ways to arrange the train is 40,320.

This is called a permutation. You would solve this in the following way: 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1. This could also be written as 8!. The answer would be 40,320. Hope this helps.

Solving linear equation 7-x=19

Answers

x is equal to -12
7-(-12)=19

Answer:

x = -12

Step-by-step explanation:

To solve an equation, you want to "undo" what has been done to the variable. Here, it has been multiplied by -1 and that result added to 7. In general, you want to "undo" these operations in reverse order.

First, you need to subtract 7 to undo the addition of 7. Of course, anything you do to one side of the equation is also done to the other side:

7 -x -7 = 19 -7

-x = 12 . . . . . . . . simplify

Now, you want to undo the multiplication by -1. Multiplication (or division) by -1 will take care of that:

(-1)(-x) = (-1)(12)

x = -12 . . . . . . . . simplify

The solution is x = -12.
