3d=12
This should be your equation
And if it is asking for the answer it would be 4
I hope this answer helps!
I think C I’m not sure but if you want me to explain I multiplied 12 x 10 and 20 x 6 and they both equal 120. So then I added 120 + 120 and got 240. Then u just added 8 because 8 was never use. Which will now look like 240 + 8 and that equal 248. :)
You know that 1 km=1000 m, then the length of the road
km is
metres.
A group of 8 people are picking up litter along the road and each person is assigned an equal section of the road. The whole road has length 800 m, then for each person will be assigned 800:8=100 m of the road.
If you want to know the length of each part in km, then 1 m=0.001 km and 100 m =1 m·100=0.001 km ·100=0.1 km.
Supplementary angles are two angles that add up to 180 degrees. so....<3 + <4 = 180 <3 is 117 so sub in 117 for <3 117 + <4 = 180 <4 = 180 - 117 <4 = 63 degrees
