Answer:
a) 3
b) 3
c) because of the permutations and combinations involved
Step-by-step explanation:
a) Determine the smallest number of cars needed
The number of cars are the same as conflict free cars
hence we can group the friends without conflict into the same car
1st car we will have : ACFI in it
2nd car we will have : GD in it
third care we will have : BEJH in it
∴ number of car needed = 3
b) number of conflict free cars = 3
c) Coloring is important in the question because of the permutations and combinations involved
Answer:
Angela paid 679,05 for the couch
Step-by-step explanation:
425*70/100=29.750
29.750/100= 297,5
297,5+425=722,5
722,5*6/100=4.335/100=43,45
722,5-43,45=679,05
Answer:
≈ -2.76
≈ -2.8 (rounded to nearest tenths place)
Step-by-step explanation:
A rate is a ratio where time is usually involved such as 60 km/ 1 hour.
So, the answer is true.
x = 2
solve 4x + 6 = 2x + 10
subtract 2x from both sides
2x + 6 = 10
subtract 6 from both sides
2x = 10 - 6 = 4
divide both sides by 2
x = 
= 2
as a check f(2) =(4 × 2 )+ 6 = 14 and g(2) =( 2× 2) + 10 = 14
