Answer:
2. 11x - 10
3. -8 + 11x - 2
5. -8 + 6x + 5x -2
Step-by-step explanation:
To find the equivalent expressions, find the solution to the expression -2(4 - 3x) + (5x - 2). All expressions that are within the solving process <u>or</u> have the same solution are equal to the given expression.
-2(4 - 3x) + (5x - 2)
-2(4 - 3x) + 5x - 2
-8 + 6x + 5x - 2
-8 + 11x - 2
11x - 10
In this case, the equivalent expressions were within the solving process. From this, we can see that the equivalent expressions are 11x - 10, -8 + 11x - 2, and -8 + 6x + 5x - 2. Aka choices 2, 3, and 5.
hope this helps!
N= the # of books
So you're trying to find n and you have the cost for the printed books, which is 15,000, so you would set up your equation like this:
15,000=500+10n
Subtract 500 from each side
14850=10n
Divide by 10
n=1,485 books are printed
X + y = 125
x - y = 47
---------------add
2x = 172
x = 172/2
x = 86
x + y = 125
86 + y = 125
y = 125 - 86
y = 39
ur 2 numbers are 39 and 86
