Need a picture or some other information to find the answer.
Answer:
80.2 pounds of cheaper beans and 109.8 pounds of high quality beans.
Step-by-step explanation:
Let x represent pounds of high quality beans and y represent pounds of cheaper bean.
We have been given that Sarah needs to prepare 190 pounds of blended coffee beans. We can represent this information in an equation as:
We are also told that Sarah needs to prepare 190 pounds of blended coffee beans selling for $3.80 per pound. She plans to do this by blending together a high-quality bean costing $4.75 per pound and a cheaper bean at $2.5.
We can represent this information in an equation as:
Upon substituting equation (1) in equation (2), we will get:
Therefore, Sarah should use 109.8 pounds of high quality beans.
Upon substituting in equation (1), we will get:
Therefore, Sarah should use 80.2 pounds of cheaper beans.
Let William be x years old.
Thomas = (4 + x) years
In five years,
William = (x + 5) years
Thomas = 4 + x + 5 = (9 + x) years
Given, in five years sum of their ages is 24.
x + 5 + 9 + x = 24
2x + 14 = 24
2x = 24 - 14
2x = 10
x =
x = 5
Hence, William is 5 years old and Thomas is 9 years old.
g (f (4)) = -24
Explanation:
g(n) = 4n
f (n) = -2n + 2
f(4) means n = 4
f(4) = -2(4) + 2
f(4) = -8 + 2
f(4) = -6
g (f (4)) means n = f(4) = -6
g(-6) = 4(-6)
g(-6) = -24
g (f (4)) = g(-6)
Therefore, g (f (4)) = -24
