Answer:

With algebraic expressions, you can’t add and subtract any terms like you can add and subtract numbers. Terms must be like terms in order to combine them. So, you can’t always simplify an algebraic expression by following the order of operations. You have to use the distributive property to rewrite the expression and then combine like terms to simplify. With numeric expressions, you can either simplify inside the parentheses first or use the distributive property first.

Please mark Brainliest!

Plan A = 10x + 144
Plan B = 48 + 22y
Equate them
10x + 144 = 22y + 48
22y - 10x = 144 - 48
22y - 10x = 96
divide by 2
11y - 5x = 48
What I did was just use trial and error at this point.
11(8) - 5(8) = 48

8 visits must a person make for plan A to plan B.

If 5 times the square of an integer is added to 3 times the integer, the result is 2. Find the integer. (Simplify your answer co

Hello from MrBillDoesMath!

Answer: x = -1

Discussion:

Let x be the unknown integer. Then

5 x^2 + 3x = 2 or

5x^2 + 3x -2 = 0 or (factoring)

(x+1) ( 5x -2) = 0

so x = -1 (the other value of x, +2/5, is not an integer)
