Answer:
Step-by-step explanation:
Bill + 220
Total is 538 so subtract 220 which gives you 318.
318/2 = 159
159+220 for Bill = 379
Bob has 159
Add 159 + 220 for Bill and 159 for bob = 538
So Bill has 379
and Bob has 159
Answer:

Step-by-step explanation:
Answer:
-5
explanation:
what
Using proportions, it is found that the life span of the person would be 14 years, 212 days and 22 hours shorter.
---------------------------
- 2 packs a day for 35 years is 40 cigarettes a day for 12775 days, as
. - Thus, a total of 511000 cigarettes, as
. - Assuming each cigarette costs 15 minutes of life, the person loses 7665000 minutes of life, as
- One year has 525600 minutes, thus the person loses 14 years of life, as
- Looking at the decimal part, the person loses 212 days of life, as
- Again looking at the decimal part, 22 hours, as
- Thus, the person loses 14 years, 212 days and 22 hours of life.

Answer:
x = -2, y = 3
Step-by-step explanation:
2x + 3y = 5
5x - 2y = -16
In order to find the value of a variable, we must eliminate the other variable by multiplying the equations to get the same coefficient.
We can multiply the first equation by 5 and the second one by 2 to get the same coefficient for x, the equations then become:
10x + 15y = 25
10x - 4y = -32
Now we can subtract:
19y = 57
y = 3
Since we know the value of y, we can substitute it into one of the original equations:
2x + 3(3) = 5
2x + 9 = 5
2x = -4
x = -2
