Answer:
2, 4 and 6 are consecutive even integers that fit the criterion.
Step-by-step explanation:
Model the problem as an equation
let a be first integer, b be second, c be third
8a = b+c+6
Since these are consecutive even integers:
b = a + 2
c = b + 2 = a + 4
Substitute these equivalents into the equation
8a = (a+2)+(a+4)+6
Combine like terms
8a = a+2+a+4+6
8a = 2a + 12
Isolate a
6a = 12 (divide both sides by 6)
a = 2
Sub a=2 into b=a+2 and c=a+4
b=a+2 = 2+2 = 4
b=4
c=a+4 = 2+4 = 6
c=6
40s=360+30a
40s+30a=$3960
40s=360+30a
40s/40=360+30a/40
s = 9+3/4a
40(9+3/4a) +30a=$3960
360+30a+30a=$3960
360+60a=$3960
360-360+60a=$3960
60a=$3960
60a/60 = $3960/60
a= $60
The algebra book is $60
Square root 48 because it can't be written as a fraction with integers
Answer: 105
Step-by-step explanation:
Flow Load Distance Id
A - B 50 2 100
C-A 5 1 5
Total = 105
Recall that The load-distance method is a mathematical model used to evaluate locations based on proximity factors. The objective is to select a location that minimizes the total weighted loads moving into and out of the facility. The distance between two points is expressed by assigning the points to grid coordinates on a map.
From the table above, it is shown that there is movement from A - B and from C - A , travelling from A could be done in 2 ways , either from A - B directly or From A - c , and it is said that none travel between C and B .

Answer:
12+4=4+12
2+7+0=2+7
17+(-17)=0
Step-by-step explanation:
first one is clear
second one is a associative property
third onw can be because 2+7+0 is 14 and 2+7 is also 14
17 +(-17) is 0 and the other side it is zero
