Answer:
40 minutes
Step-by-step explanation:
2/3 x 60 = 40
Probably the subsitution method
y=1/2x
subsitute that fr y
2x+3(1/2x)=28
2x+3/2x=28
times 2 both sides
4x+3x=56
7x=56
divide by 7 both sides
x=8
sub back
y=1/2x
y=1/2(8)
y=4
(x,y)
(8,4)
Divide 224 by 8 and you will get 28.
The values are x = 8 and x = -1.
To find the undefined values, we need to know when the denominator is zero.
To do this, we need to factor it and find the value that would make either factor equal to zero.
If factors to: (x - 8)(x + 1)
Therefore, the undefined values would be at 8 and -1.
Answer:
a=b+cd
c=b/c/a or c^2=b/a
Btw ^2 means squared or to the second power.
this might no be the answer you are looking for though
