Answer:
1=15.7
2:31.4
3:12.5
Step-by-step explanation:
1=5×3.14=15.71
2:5×2=10×3.14=31.42
3:39.25÷3.14=12.5
hope this helps
Step-by-step explanation:
4x+9y=28
-4x-y=-28
8y=0
divide both side by 8
y=0
solve for X in equation 1
4(X)-9(0)=28
4x-0=28
4x =28
divide both side by 4
4x/4=28/4
X= 7
y=0,x=7
8x8x8=512
hope this is what its asking
Answer:
Both calculated the slope as 1/3
Step-by-step explanation:
Avis:
Rise = 4
Run = 12
Rise goes over the run: 4/12
4/12 simplifies into 1/3
Alec:
Rise= 2
Run= 6
Rise goes over the run: 2/6
2/6 simplifies into 1/3
