I'm thinking this is what the problem looks like:

. The first thing to do is to move the

over to the other side because it has a common denominator with the other side. Doing that and at the same time combining them over their common denominator looks like this:

. The best way to solve for x now is to cross-multiply to get 3(4-x)=-4(x-4). Distributing through the parenthesis is 12 - 3x = -4x + 16. Solving for x gives us x = 4. Of course when we sub a 4 back in for x we get real problems, don't we? Dividing by zero breaks every rule in math that there ever was! So, yes, the solution is extraneous.
Account balance is not proportional to the number of weeks.
Answer:

Step-by-step explanation:
let length of calble = L
distance from 10-foot pole = x ft
Moving from the top of the 10-foot pole to point x, we have
From the diagram that

Take the square root of both sides

Moving from point x to the top of the 12-foot pole, we have
From the diagram that

Take the square root of both sides

Amount of cable used, L = L1 + L2

Answer
125 of each meal are ordered
Step-by-step explanation:
You first multiply 7 x 125, which will get you 875
Next, you multiply 5 x 125 and get 625
Add that together and you get 1500
Is there any other information lol
