Answer:
t ≥ 0.2c
Step-by-step explanation:
Her tip is at least 20% of the cost of the meal, so her tip is greater than or equal to 20% of the cost of the meal
tip ≥ 20% of the cost of the meal
t ≥ 20% of c
Another way of writing "20% of c" is multiplying the two values, so we have
20% of c = 20% * c
t ≥ 20% * c
To convert from a percentage to a decimal, we can divide the percentage by 100. Here, we have
20% = 0.2
t ≥ 0.2 * c
Answer:
1 it 111111111111111111111111111111111111
Step-by-step explanation:
I:a*b=48
II:a/b=3
II': a=3b
insert into I:
3b*b=48
b*b=16
b=4
insert b=4 into I:
a*4=48
a=12
solution: a=12, b=4
12*4=48
12/4=3
