Answer:
72 and 108
Step-by-step explanation:
540/30= 18 *4 = 72
and
810/30= 27*4=108
Answer:
42 because 3 tens is 30 and 12 ones is 12. so you do 30 + 12 = 42
1) let both have x ,
so putting in eqn ;
4x+0.50 = 9x-3
5x=2.50
x=0.50
therefore both have 50 p in the beginning !!
2) let the number be x
so in eqn;
(x+18)/2=5x
x+18=10x
9x=18
x=2
so the number must be 2 !!
