Answer:
8
Step-by-step explanation:
Let x represent the number. Then the reciprocal is 1/x. The quotient of 25 and the number is 25/x. The problem statement tells us ...
3 + 1/x = 25/x
Subtracting 1/x, we have ...
3 = 24/x
x = 24/3 = 8 . . . . . . . . multiply by x/3
The number is 8.
Hello!
Our two angles are corresponding. Therefore they are congruent. This gives us the equation below.
3x+2=5x-10
We subtract 5x from both sides.
-2x+2= -10
We subtract 2 from both sides.
-2x=-12
We divide both sides by -2.
x=6
Therefore, our answer is A) 6.
I hope this helps!
counterexample.
One way to show that a statement is NOT a good definition
is to find a counterexample. In description, counterexample is an exception to
a “proposed general rule or law”. Philosophically, counterexample somehow
generalizes a set of ideas or a notion declared in its position. For example,
all colors are white. Therefore it is wrong to say that red, orange, blue or
any other “color” is not a color by which the statement declared itself.
Moreover, in mathematics counterexamples are utilized frequently
to testify theorems' limitations.
Answer:
d = 711 miles
Step-by-step explanation:
The speed s of the car is given by :
...(1)
Where
d is the stopping distance
We need to find the stopping distance of a car travelling at 80 mph.
Rearranging equation (1) for d.
or
d = 711 miles
So, the required stopping distance is 711 miles.
