Step-by-step explanation:
For the income to exceed the cost, a minimum of 34 complete cups of lemonade must be sold.
Mathematical expressions with inequalities are those in which the two sides are not equal.
Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), larger than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
The cost in dollars C(x) = 10 + 0.20x.
The revenue in dollars, R(x) = 0.50x.
For revenue to outpace cost
R(x) > C(x)
0.50x > 10 + 0.20x
0.50x - 0.20x > 10
0.30x > 10
x > 10/0.30
x > 33.333
Hence, For the income to exceed the cost, a minimum of 34 complete cups of lemonade must be sold.

g(x) = 4x + 5
find (f+g) (3)
Answer:
23
Step-by-step explanation:
(f + g)(3) = f(3) + g(3)
f(3) = 3(3) - 3 = 9 - 3 = 6
g(3) = 4(3) + 5 = 12 + 5 = 17
Then
(f + g)(3) = 6 + 17 = 23
b. How many trombones are in the orchestra? Please help, I'm in 8th grade! (:Thank youu..
Answer:
Givens
So, if there are 9 violas, the number of trombones is three, because 9 violas represents a triple proportion, which means we need to multiply by 3 to find the number of trombones according to the given proportion.
The expression that gives the number of trombones is
The number of trombones is 3, there are 3 trombones while there are 9 violas.
