This one is easy.
<span>–8.6 = –4.1 + x
</span>
So, what you have to do is add 4.1 on both sides.
You do this because you want to get X alone. when you do,
-8.6+4.1=-4.5
X=-4.5
The answer is B
Answer:
Because of cars, and factories making it everyday.
Step-by-step explanation:
The decimal is irrational because it is not repeating.
Answer:
a= 1
b= 0
Step-by-Step Explanation:
I am not 100% sure on part A, however part B is correct because the difference between -2 and -1 is 1, so if you add 1 to -1 you get 0. Hence B= 0.
Again I am not 100% sure on part A, so you may need a second opinion.
Answer:
Radius = 6 ft
Diameter = 12 ft
Circumference = 37.7 ft
Step-by-step explanation:
The radius of the circle is the measurement from the center of the circle to the edge. The diagram gives us the radius, 6 ft.
Radius = 6 ft
The diameter of the circle is the measurement from the edge of the circle through the center, extending back to the edge. The diameter is equal to double the radius.
6*2=12
Diameter = 12 ft
The circumference of the circle is the distance around its edge or the perimeter of the circle. We use the below equation to solve for it:
where
is the diameter
Plug the diameter (12) into the equation

(This answer is approximate)
Circumference = 37.7 ft
I hope this helps!
