Answer:
Hola,
1, 2, 4, 5, 10, 20
Step-by-step explanation:
3.60/6 = 0.60...so it costs 60 cents per oz
2 oz at 0.60 per oz = (2*0.60) = 1.20...so a 2 oz bag costs less then 1.25
Answer:
A_ 1,2,4,5,-1, or,-2
3 plus any of these will always leave you with a positive number of 1-8
B_ -1, -3, -4, -5, or 1
-2 plus any of these will leave you with a negative number of -7 through -1
C_ 1+(-1)
2+(-2)
3+(-3)
4+(-4)
5+(-5)
since all the numbers are 1-5 are both negative and positive these will cancel out and equal to zero.
Step-by-step explanation:
Answer:
6 Chickens
Step-by-step explanation:
Let H represent the number of horses and C represent the number of chickens. Since there are 32 legs altogether this means that on equation to use would be given by:
2C + 4 H = 32 (Eq. 1)
Another equation can be made from the fact that there are 11 heads or 11 animals altogether which can be written as:
C + H = 11 (Eq. 2)
From Eq. 2, solve for the number of chickens:
C + H = 11
C = 11 - H (Eq. 3)
Substituting Eq. 3 in Eq. 1, the number of horses can be determined:
2 C + 4 H = 32
2 ( 11 − H ) + 4 H = 32
22 − 2 H + 4 H = 32
2H = 32 − 22
2 H = 10
H = 5 Eq.4
Putting Eq.4 in Eq.1
2C + 4*5 = 32
2C = 32 - 20
2C = 12
C = 12/2
C = 6
Answer:
42 miles
Step-by-step explanation:
so average is found by taking the sum of numbers of all the numbers given, and dividing by the number of numbers
so
68+25+33= 126
126/3=42
they drove an avg of 42 miles
hope this helps
