21 + 15 = 36
36 x 3 = 108
Their father donated $108 to charity
Answer:
Gordon gets 16£, Henry gets 24£ and Sarah gets 8£
Step-by-step explanation:
Let the ratio be 2x + 3x + 1x
Total amount = £48
So;
2x + 3x + x = 48
6x = 48
x = 48 / 6
x = 8
Now
2x = 16
3x = 24
x = 8
Answer:
16
Step-by-step explanation:
-21x+121
x=5
substitute x
-21(5)+121=-105+121=16
Yes
(2+5)+8=2+(5+8)
7+8=2+13
15=15
