12 divided by 10 is 1.2. 15 multiplied by 1.2 is 18 so x equals 18
Answer:
10 pounds.
Step-by-step explanation:
Let x pounds be the amount of mixed nuts we require.
Amount of peanuts in this mix = 0.70x pounds. Amount of peanuts in the 20% mix = 0.20*15 = 3 pounds.
So we have the equation:-
0.70 x + 3 = 0.40(x + 15)
0.70 x + 3 = 0.40(x + 15)
0.70x + 3 = 0.40x + 6
0.70x - 0.40x = 6 - 3
0.30x = 3
x = 10.
Answer:
Unreduced: (4) + (5 • x) + (-9) + (4 • x)
Reduced: 9x – 5
Answer:
The vertex of this graph is (5, 3)
Step-by-step explanation:
In order to find the vertex of any graph in vertex form, we need to look at the base form.
f(x) = a|x - h| + k
The point (h, k) is the vertex. You can see that 5 lines up with the h term and 3 lines up with the k term. This gives us a vertex of (5, 3)
Answer:
The correct answer is 206550 pigs.
Step-by-step explanation:
First of all you need to calculate the constant growth rate, which is given by the formula 
where f is the value at the end of the year, s is the start value of that year, and y is the number of years.
From the excercise facts, we know that for 1 year (y=1), the final value is 421 (f=421), and the start value is 16 (s=16). Replacing them in the formula we get : 
So, the constant growth rate equals 2531.25.
Next, we have to multiply the starting amount of pigs times the constant growth rate times the amount of time that passed to get the final quantity of pigs. This would be 
and this gives us a total amount of 206550 pigs.
Have a nice day.
