x=12
Step-by-step explanation:
8x6=48 =x
6x6=36
equation= 6x*6-48=x
Answer:
Step-by-step explanation:
Let the number of blue marbles be x
The number of green marbles = 3x - 2
Total marbles= 18
x + 3x -2 = 18
4x - 2 = 18
4x = 18+2
4x = 20
x =20/4
x =5
The number of blue marbles = 5
The number of green marbles = 3*5 - 2 = 15 -2 = 13
Answer:
76.4 m
Step-by-step explanation:
The race track has two straights and two semi circles.
Each straight is 80m
total perimeter for the straights is 80 * 2 = 160m
two semi circles which creates a full circle
perimeter of a full circle =
d
NB : (d) is the diameter
therefore we can find the value of the diameter
400 = 160 +
d
400- 160 =
d
240 =
d
d = 240/
d = 76.394.....
<u>d = 76.4 m</u>
