The segment addition postulate tells you that
... JK + KL = JL
a) Filling in the given information, you have
... 3n + (5n-7) = 25
... 8n = 32 . . . . . . . . . . . collect terms, add 7
... n = 4 . . . . . . . . . . . . . divide by 8
b) Now, you know that
... JK = 3n = 3·4 = 12
... KL = 5n-7 = 5·4-7 = 13
The segments are: JK = 12; KL = 13.
Answer:
25%
Step-by-step explanation:
Since there are 24 apples, and 6 are bad, to find the percentage of the bad apples, you do bad apples/total apples
6/24=.25
0.25 is 25%
Answer:
30$ for a pack of 15
Step-by-step explanation:
12$ ÷ 6 to get the price for 1 can, then use that to multiply by 15 to get how much 15 cans cost.
The Answer is -4x^2+10x+4
-4x^2 is not effected, as it has no like terms.
3x-(-7x) is equivalent to 3x+7x which equals 10x.
-5-(-9) is equivalent to -5+9 which equals 4.
Each complete cleaning requires 6 drops of cleaner. Let's convert that to ml:
6 drops 1 ml 3 ml cleaner
----------- * ------------- = ------------------- = 0.3 ml cleaner per cleaning
20 drops 10 cleanings
Recall that 1 bottle contains 30 ml cleaning fluid.
How many cleanings is one bottle of fluid good for?
1 bottle 0.3 ml
----------- = ----------- => x = 100 cleanings/bottle
x 30 ml
