The expression simplified in form is answer : A
Answer:
x=-11/8
Step-by-step explanation:
First use the Distributive property on [3(2x-1)]:
5x+6x-3=3x-14
Now combine alike terms:
11x-3=3x-14
Now add three to both sides:
11x=3x-11
Now subtract 3x from both sides:
8x=-11
Now divide both sides by 8:
x=-11/8
This fraction cannot be simplified meaning your final answer SHOULD be -11/8
Radius=8/2=4cm
circular area=4*4*3.14=50.24cm₂
volume=50.24*12=602.88cm₃
The answer is 602.88cm₃
Answer:
It will take the police car 3.5 hours to travel a distance of 175 miles traveling at a rate of 50 miles/hour.
Step-by-step explanation:
If a car is traveling at a constant speed of 50 miles/hour and we wish to know how long it will take it to travel a distance of 175 miles, we will use this formula
d = r*t
Where d is the distance traveled in miles
r is the rate of speed in miles/ hour, and
t is the time in hours
d in this case is 175 miles and r is 50 miles/hour, plugging this in, we have
175 miles = (50 miles/hour) * t Divide both sides by 50 miles/hour
Our miles unit will cancel out, leaving us with
3.5 hours = t
The advantage of the graphing calculator is that you just have to find two independent equations, introduce them in the calculator and it will find the intersection point ot the two graphs.
The equations that you have to introduce are:
1) y = 2.25x + 24
2) y = 2.75x + 23
The algebraic solution, which will give you the same coordinates of the intersection point of the graphs is
2.25x + 24 = 2.75x + 23
2.75x - 2.25x = 24 - 23
0.5x = 1 => x 1 /0.5 = 2.
Answer: 2
