Multiply the number of bags by the ounces in each bag:
8 x 3 1/2 = 28 total ounces.
Divide total ounces by the number of hikers:
28 / 12 = 2.33 ounces per hiker.
1 cup = 8 ounces.
Divide the number of ounces per hiker by the number of ounces in 1 cup:
2.33 / 8 = 0.29 cups per hiker.
Answer:
-1, 1 and 3.
Step-by-step explanation:
Let the integers be n, n + 2 and n + 4, then
6( n + n+2 + n + 4) = 18
6(3n + 6) = 18 Divide through by 6:
3n + 6 = 3
3n = -3
n = -1
So the integers are -1, 1 and 3.
System A:
6x + y = 2
-x - y = -3
System B:
2x - 3y = -10
-x-y = -3
Solve:
System A:
6x + y = 2
y = 2 - 6x
-x - (2-6x) = -3
-x - 2 + 6x = -3
5x = -3 + 2
5x = -1
x = -1/5
y = 2 - 6(-1/5)
y = 2 + 6/5
y = 2 + 1.2
y = 3.2 System A: x = -1/5 or -0.2 ; y = 3 1/5 or 3.2
System B:
2x - 3y = -10
2x = -10 + 3y
x = -5 + 1.5y
-x - y = -3
-(-5 + 1.5y) -y = -3
5 - 1.5y - y = -3
-2.5y = -3 - 5
-2.5y = -8
y = 3.2
x = -5 + 1.5(3.2)
x = -5 + 4.8
x = -0.2 System B: x = -0.2 ; y = 3.2
<span>B) They will have the same solution because the first equations of both the systems have the same graph.</span>
