Answer:

16, -16, 14, and -14

Step-by-step explanation:

The easiest way of solving this question is by setting up an equation. Let's use "n" to represent any random possible integer.

n (n + 2)  = 224

Simplifying:

x^2 + 2n - 224 = 0

(n + 16)(n - 14) = 0

n = -16, 16 or n = -14, 14

<u>Check:</u>

16 * 14 = 224

-16 * -14 = 224

Thus, answers of 16, -16, 14, and -14 all work correctly.

There were 287 music books and 134 science books in the store. After some books were sold there are 159 books left. How many boo
stiks02 [169]

Answer:

262 books sold

Step-by-step explanation:

This is a very vague word problem, but if it truly is just asking the amount of books sold (regardless of music or science), here's how to get the answer:

1. 287+134=421 - first you want to add together the two types of books to get the total amount of books in the store

2. 421-x=159 - create an equation and solve.

3. -x=-262 - follow order of operations and subtract 421 on both sides in order to isolate the variable

4. x=262 - divide each side by -1 to make the variable positive.

If you'd like an easier way, you can just:

1. 421-159=262 - it's easier, but my math teacher would count us wrong if we didn't do equations a specific way. Good luck!

Solve for w and simplify this fraction 3/2w=-20​
AleksAgata [21]

Answer:

If I'm correct, the answer should be  negative 40/3.

Step-by-step explanation:

Because you first combine multiplied terms into a single fraction, then you multiply all terms by the same value to eliminate fraction denominators. Now you simplify it, by canceling multiplied terms that are in the denominator and then you multiply the numbers. Now you will divide both sides of the equation by the same term. Finally, you will simplify the equation.

(Hope this helps) I had to get a little help myself on this problem)

A student bought 5 coats at $86 each and paid for them with only $20 bills. How many bills did it take ?
aleksandr82 [10.1K]
It took 22 $20 bills . $86 x5= $430
Then $430 divide by 20 = 21.5
So you can’t have half a bill do the answer has to be rounded up to 22 twenty dollar bills
