Step-by-step explanation:
Answer: radius = 6.18 (I don't know what solutions you have, but the actual answer for the radius is about 6.18 cm so which ever is closest.)
Step-by-step explanation:
the area of a circle is \pi r^{2}
*rewrite your equation solving for radius
r=\sqrt{A/\pi } =\sqrt{120/\pi } = 6.18
You have to distribute the 4 to the numbers in the parenthesese. So 4 times 3x which is 12x and 4 times 5 which is 20 so now you get 12x plus 20 equals 8. Now you have to subtract 20 from 8 which is -12 so now you have 12x=-12 now divide the 12 from x and 12 from -12 and so now you have x=-1
Answer:
4 Hours.
Step-by-step explanation:
You would set this up as an equality where x represent hours
19.00 + 1.50x = 14+2.75x
You then get the x on one side by subtracting 14 from both sides and 1.50x from both sides.
5 = 1.25x
Divide both sides by 1.25 to x by itself.
4 = x
