Answer:
The choose B. x = 7 , x = – 15
(x+4)-5=6
x +4-5=6 —> x=6-4+5 —> x= 7
– (x+4)-5=6 —> -x -4-5=6—> x = -4 -5 -6 —> x = – 15
I hope I helped you^_^
Answer: 24
Step-by-step explanation:
10/5 = 1/x
cross multiply
10x = 5
x = 5/10
x = 1/2...u need 1/2 gallon per fish
Here we use the equation

Taking points (0,4), (1,2)
Substituting the point (0,4) , we will get

Substituting (1,2) we will get

So we have

Therefore , required equation is

The 2 lines are parallel, so the 2 sides(e.g. 1 and 2/ 3 and 49) add up = 180 and In this case the 2 sides are equal as u can see from the original diagram so the angle of 2 is 180-49=131.
