Answer:
Step-by-step explanation:
Given:
w = 250 + 132.5t
The two possible solution to the equation includes
1. If the value of w is given, the w value will be substituted in the equation to find the value of t
2. If the value of t is known , the value of t will be substituted in the equation to find the value of w
That is,
w = 250 + 132.5t
132.5t = w - 250
t = (w - 250) / 132.5

Answer:
- 3.84 pounds of $2.50/lb candy
- 13.16 pounds of $0.95/lb candy
Step-by-step explanation:
Let x represent the number of pounds of $2.50 per pound candy. Then 17-x is the number of pounds of $0.95 per pound candy. The total cost of the mix is ...
0.95(17 -x) +2.50x = 1.30(17)
16.15 +1.55x = 22.10 . . . . . . . . . simplify
1.55x = 5.95 . . . . . . . . . . subtract 16.15
x ≈ 3.84 . . . . . . . . . divide by 1.55
17-x = 13.16
The grocer should use 3.84 pounds of $2.50 candy and 13.16 pounds of $0.95 candy.
To shift a function f(x) to left or right, use the rule
g(x)=f(x-h)
where g(x) is the result of f(x) shifted h units to the right.
To shift 4 units to the right,
g(x)=f(x-4)
Answer = p=12-4 -12=17=18+19
p-q
p=12
So the chickens have 1 beak and 2 legs and the sheep have 4 legs.
So since there are 8 chickens we know that there are 8 beaks
If we multiply 2 legs times 8 chickens we get 16
If we multiply 4 legs times 14 sheep we get 56
The number of legs is 16+56=72
So we have 8 beaks and 72 legs or 8:72
Divide both sides by 8 to simplify and you get 1:9 as the answer
