Step-by-step explanation:
In order to turn a percent into a decimal you need to move the decimal point already in the percent 2 spaces to the left. Or if your trying to convert a decimal to a percent move it 2 times to the right.
Answer:
x = 7, y = 24
Step-by-step explanation:
23x -16 + 8x - 21 = 180 because they are supplementary angles
31x - 37 = 180
31x = 217
x = 7
23(7)-16 = 7y - 23 because they are vertical angles
168 = 7y
y = 24
5x - 3y = 9
5x = 9 + 3y
5x - 9 = 3y
( 5x - 9 ) / 3 = y
y = ( 5 / 3x ) - ( 9 / 3 ) ( I just split the common denominator to individual parts )
y = 5 / 3x - 3
