The list of pairs of integers will be created by starting with the factor pairs for 30.
1 x 30
2 x 15
3 x 10
5 x 6
Then multiply these with negative integers which will result in a positive answer.
-1 x -30 (This means the opposite of one groups of negative 30, which is posiitve 30).
-2 x -15
-3 x -10
-5 x -6
Answer:
|x - 2| = 15 ; |x + 2| = 15
Step-by-step explanation:
Given that:
Wait time = 15 minutes
Variation in wait time depending on level of hotness = 2 minutes
X ± 2 = 15
x + 2 = 15 or x - 2 = 15
x = 15 - 2 = 13 or x = 15 + 2 = 17
Hence, to express the above as an absolute value equation :
|x - variation| = mean time
|x - 2| = 15 ; |x + 2| = 15
Answer: In 1 hour water flowed out = 74/17 gallons
Step-by-step explanation:
Given as ,
The quantity of water flowed out of tank = 18 1/2 gallons
= 37/2 gallons
The time spend in flowing water out of tank = 4 1/4 hours
= 17/4 hours
∵ In 17/4 hours , water flowed out = 37/2
∴ In 1 hours , water flowed out =
So, in 1 hour water flowed out = 37*4/17*2 gallons Answer
Answer:
22 units of wood
Step-by-step explanation:
21 x 11 = 231
22 x 11 = 242
You need 22 units of wood because with 21 units there is not enough wood by 2 feet.
7 & 8/10 or 78/10 ( which is the same thing)
