8x - 4 = 6x - 10
8x - 6x = - 10 + 4
2x = -6
x = -3
3x = -9
Answer:
7.3
Step-by-step explanation:
In order to find the hypotenuse, we just need to use the Pythagorean Theorem.
Remember, that this theorem only works for right triangles.
This theorem states that a^2+b^2=c^2
This is where a and b are legs of the triange, and c is the hypotenuse.
Knowing this, we can plug our values in.
6.4^2+3.5^2=c^2
Simplify.
41.344+12.25=c^2
53.594=c^2
Root both sides.
c=7.32 (about)
Round that to tenths.
c=7.3
9 I think because 1/4 needs to have 4 of those to be a whole so yeah 9.
If we are going to analyze the problem very well, the equation that we will be able to make would be: 2x + 6y = 72
72 is the oz of water conditioner to use in his fish tanks.
small tanks would require 2 oz of conditioner
large tanks would require 6 oz of conditioner
There is only one point which satisfy's the above equation.That is the points of (0, 12) and (36, 0)
