There is 7.5 killograms in 7500 grams.
0.001 killograms are in a gram, so I did 0.001 x 7500
Step-by-step explanation:
first you have to find the value of X. So you take both expressions and make them equal to 180 degrees. Then you solve for X. Once you do that X should equal 30. Then in place of X plug in 30 and solve. it should look like this (3(30)+22). The answer is 112 degrees.
You could of also looked at your angle and saw it was an obtuse angle. The only answer that was obtuse was 112 degrees.

Answer:
yellow : 8
Red : 4
Step-by-step explanation:
Yellow : Y and Red : R
R : Y = 12
They need to add up to 12 because its the total.
We know that yellow is twice the amount so
4×2= 8
so if yellow was to be times by 2 itd be 8 which will still add up to 12.
