Answer:
p = (105-2l)/13
Step-by-step explanation:
4l + 26p = 210
Isolate 26p by subtracting 4l from both sides
26p = 210-4l now divide by 26
p = (210-4l)/26 you can simply
p = (105-2l)/13
Answer:
Let ten's place digit =x and unit place digit =y
Number=10x+y
x+y=5 ...(i)
10x+y−9=10y+x
9x−9y=9x−y=1 ...(ii)
from (i) and (ii) we get,
x=3,y=2
∴Number=10×3+2=32.

Answer:
79.95
Step-by-step explanation:
The first step is to rewrite the percentages into decimals so they can be added or subtracted easier. To turn a percentage into a decimal, remove the percent sign and move the decimal two spaces to the left (in other words, divide the number by 100).
12% becomes -0.12
8% becomes 0.08
Now, let's solve.
79.99 - 0.12 + 0.08
Evaluating 79.99 - 0.12, the equation becomes 79.87 + 0.08.
Evaluating 79.87 + 0.08, we get the final answer, 79.95.
That depends on the total distance of the race, which you
have not bothered to mention.
If the team has exactly enough runners to run the entire race,
one at a time, then the number of runners needed is ...
(3) times (the total distance of the race, in miles) .
