Answer:
-3(a-b) < 0. divide both sides by -3 and reverse the inequality sign: 0 0
Step-by-step explanation:
the answer is A cuz non of the number are repeated
Answer:
C = 5x + 8y + 15z + 1.5r + 15
Where C = cost for the family of 6
Step-by-step explanation:
Let:
x = number of children under 10
y = number of children 11-16
z = number of all others (16 and above)
r = number of rides
Cost:
Under 10 = $5
11-16 = $8
Above 16 = $15
Ticket Ride = $1.50
We have an additional $15 for parking
So from there, we can find the cost by getting the total:
Cost for each TOTAL
x x $5 $5x
y x $8 $8y
z x $15 $15z
r x $1.50 $1.50r
Constant : $15 for parking
So the expression would then be:
C = 5x + 8y + 15z + 1.5r + 15
Given:
6 family members
x = 3
y = 1
z = 2
r = 5
We fill in the formula
C = 5x + 8y + 15z + 1.5r + 15
C = 5(3) + 8(1) + 15(2) + 1.5(5) + 15
C = 15 + 8 + 30 + 7.5 + 15
C = 75.50
Answer:
38.5 years old
Step-by-step explanation:
Let us represent Mrs.Kelly's age with the parameter (k). It is given that her brother is (15) years younger than her, thus his age is (k - 15). It is given that the sum of their ages is (62). Therefore one can form an equation with the given information and solve for the unknown.
(Mrs.Kelly's age) + (Brother) = (62)
Substitute,
(k) + (k - 15) = 62
Simplify,
k + k - 15 = 62
2k - 15 = 62
Inverse operations,
2k - 15 = 62
2k = 77
k = 38.5
30= 3*10
30= 3*2*5
48= 12*4
48= 3*4*4
48= 3*2*2*2*2
60= 3*20
60= 3*10*2
60= 3*2*5*2
The GCF is 3*2 because all 3 numbers contain a 3 and a 2 in their prime factorizations.
Final answer: 6
