6(3x+8)+32+12x=
18x+48+32+12x=
30x+80
Step-by-step explanation:
The radius is half the size of the diameter. So, we will divide 60 by 2 in order to get the radius.
60 ÷ 2 = 30
So, the radius of the circle is 30 mm
Answer:
(-5,2)
Step-by-step explanation:
Answer: 455 mph
Step-by-step explanation:
if train one is traveling one way at 60mph, then you have to multiply that by 3.5 to see how far it traveled in that amount of time.
60 x 3.5 = 210
then, you have to multiply 3.5 by 70mph, to see how far the second train has traveled in that amount of time
70 x 3.5 = 245
finally, since both trains are moving in opposite directions, you have to add up the distances together to get the final difference
210 + 245 = 455
