Here is the answer for ur question
Answer:
C ≈ 54
Step-by-step explanation:
The circumference (C) is calculated as
C = πd ( d is the diameter )
Here d = 18 , then
C = π × 18 ≈ 3 × 18 = 54
Answer:
Marcus total score = 1 points
Step-by-step explanation:
Given:
Marcus score in the first round = 5 points
Marcus score in the second round = -4 points
Find:
Marcus total score
Computation:
Marcus total score = Marcus score in the first round + Marcus score in the second round
Marcus total score = 5 + (-4)
Marcus total score = 5 - 4
Marcus total score = 1 points
Answer:
y=17/3
Step-by-step explanation:
So you should make one -3y positive to cancel them out.
So multiply 2x-3y=43 by -1 and you get
-2x+3y=43
4x-3y=83
now +3y -3y cancel each other out
4x-2x=83-43
2x=50
x=25
Now enter 25 into the equation as x to find y
4(25)-3y=83
100-3y=83
100-83=3y
3y=17
y=17/3
