4) n=12 this is because 45/4=11.25 and dividing 135 by 11.25 equals to 12
5) n=2.5 this is because 5/2=2.5 and multiplying 1 by 2.5 equals to 2.5
hope this helps :)
To find this, simply subtract 57 from 90. 90 is the measurement for a completed compliment equation, and 57 is the part of the compliment we know.
33 is the answer
5x+4=114
5x= 110
X=22
114+ 3(22)-24=156
180-156=24
2y=24
Y=12
