Answer:
x=5, -2/3
Step-by-step explanation:
3x^2-13x=10
3x^2-13x-10=0
factor out,
(3x+2)(x-5)=0,
zero property,
3x+2=0, x-5=0,
3x=0-2=-2
3x=-2, x=-2/3
x=0+5=5, x=5

Answer:
Tank A is filling quicker
Step-by-step explanation:
The slope of line A is larger and going up faster, that tells you tank A is filling up faster than Tank B
Answer:
You multiply 5 by 1/5 to get 1. So with 2x, you multiply by 1/(2x) to get 1. That's about all you know, since we only know that x is positive.
Step-by-step explanation:
The correct answer is 120 degrees.
With the bigger triangle you can add all of the angles to get 60 degrees. (35+25)
This leaves you with a 120 degrees angle in the unmarked corner of the triangle. Any horizontal line and any triangle is 180 in total.
So with a 120 degree angle in the corner this leaves us with a 60 angle in the smaller triangle. ( The smaller triangle equals 60 degrees in all corners, it is equalateral ).
X is on a horizontal line and we now know that the one side of the line equals 60 degrees and any horizontal line equals 180 in total, this means that the measure of X is 120, (60+120)
X is 120 :)
