A number is :
_________________________________
Three quarters of it means :
_________________________________
Decrease by 20 means :
_________________________________
Equals to 82 means :
_________________________________
What is that number ?
x asked so we must solve the above equation for x.
Let's do it....
Plus sides 20
Multiply sides by 4
Divided sides by 3
Simplify
So that number is 136 .

Step-by-step explanation:
The approximate stopping distance d(in feet) is given by the formula :
...(1)
Where
v is the speed of the car in mph
We need to find the speed of the car when the distance is 200 feet
Put d = 200 in equation (1)
It is a quadratic equation. Divide the above equation by 0.05.
The solution of the above equation is given by :
Since, 1 mph = 5280 ft/hour
44.96 ft/h = 0.00851 mph
-88.96 = -0.0168 mph
Hence, this is the required siolution.
Answer:
1. The bar interval is correct, the height does not need to be changed.
2. The bar interval is not correct, the height has to change higher by 1.
3. The bar interval is not correct, the height has to change lower by 1.
4. The bar interval is correct, the height does not need to be changed.
Hi, let's there!
6x^4 -5x^2 + 12x^2 -10
Rewriting this equation as:
6x^4 + 12x^2 -5x^2 - 10
Now putting 6x^2 as commun factor
6x^2.( x^2 +2) -5x^2-10
Now putting -5 as commun factor
6x^2.( x^2 + 2) -5.( x^2 +2)
Now putting (x^2+2) as commun factor
(x^2 + 2).( 6x^2 +2)
Now putting 2 as commun factor on the expression 6x^2 +2
6x^2+2 = 2.( 3x^2 +1)
Then stay:
2.( x^2 +2).( 3x^2 +1)
