Answer: 0.6 in 10 % ; 0.4 in 15 %
Step-by-step explanation:
1. (x*10%) + (y*15%)/ x+y=12%
2. x+y = 1 x= 1-y
(0.1x + 0.15y/ x+y= 12/100) * 100
(10x + 15y/x+y = 12)*(x+y)
10x+15y= 12x + 12y
-2x=-3y
2x = 3y 2(1 - y)= 3y
2-2y=3y 2= 5y
y= 0.4
x= 0.6
Step by Step:
14 average pots x 4 days a week = average money made
14x4= 56
56 pots a 4-day week x 24$ a pot
56x24 = 1344$
Answer:
x = StartFraction 2 Over 3 EndFraction and x = StartFraction negative 2 Over 3 EndFraction.
Step-by-step explanation:
We are given a quadratic equation of single variable x as
.
There is no doubt that as the equation is of two degrees so, it will have two solutions.
Now,
⇒
⇒
and
Therefore, the solution will be x = StartFraction 2 Over 3 EndFraction and x = StartFraction negative 2 Over 3 EndFraction. (Answer)
The two angles are obtuse which is greater then 90 degrees or acute which is less then 90 degrees.
