Super easy so what your going to do is replace x with 5 and y with 3 (it says in the directions) for example number 1 3x-2y+4 so replace the variables with numbers so when there is a number next to a letter that means to multiply so 3x5-2x3+4 then you just solve and remember pemdas and when there bit two variables next to each other multiply hope this helps

East of Star, the railroad tracks intersect highway 23o as shown above. If 1=133 , find 2.

Hi there.

These two angles sum up to be 180 degrees, so they are supplementary angles. Now, since these angles sum up to 180 degrees (to form a straight line), we only have to subtract 133 from 180 to find angle 2's measurement.

180 - 133 = 47

Angle 2's measurement is 47 degrees.

Voila!

I hope this helps! Have a great day. :)
