-9(3-r)=45
-27+9t=45
9r=45+27
R=72/9
R=8
The answer is 8 not -8
The answer is 8. This is because when you substitute 8 with “a” you then solve the problem to see if it is equal to the answer. -4+8=4... -4+4=0 so that is wrong and -4+O=-4 which is also incorrect.
Hi
24% of 80 is 19.2
100% ⇒ 80
24% ⇒ x
100x = 24·(80)
100x = 1920
x = 1920/100
x = 19.2
