A) 25x+15y=650
25x+15(40)=650
Or it could be 25x=650 and 15y=650
B) No because she makes $15 for every necklace which she only has 40 necklaces 15x40=600
The answer is: 40
Step by step explanation:
The answer x = 7 is false here is why.

This further simplifies to solution,

First, I'm going to separate factor the expression inside of the square root.
sqrt[ (2/18) * (x^5) ]
sqrt[ (1/9) * (x^5) ]
We can take the square root of 1/9 easily, because 1 and 9 are both perfect squares. The square root of 1/9 is 1/3.
Looking at the x^5, we can separate it into x^2 * x^2 * x^1. The square root of x^2 is x. So, we now also have an x^2 on the outside because there are two x^2s in our expanded form.
ANSWER: (x^2 * sqrt(x)) / 3

Answer:
X=43.5
Step-by-step explanation:
The angle will equal 90 so the equation is 90=2x+3
87=2x
x=43.5
