Answer:
36
Step-by-step explanation:
Since f(x) varies directly with x, f(x) can be expressed alternatively as \[f(x) = k * x\] where k is a constant value.
Given that f(x) is 72 when the value of x is 6.
This implies, \[72 = k * 6\]
Simplifying and rearranging the equation to find the value of k:
k = \frac{72}{6}
Hence k = 12
Or, \[f(x) = 12 * x\]
When x = 3, \[f(x) = 12 *3 \]
Or in other words, the value of f(x) when x=3 is 36
Answer:

Step-by-step explanation:
The like terms are the ones containing the variable 'c'. They are combined by adding their coefficients.
Working just with the coefficients of c, we have ...

Then the simplified expression is ...
(2 3/4)c +(3 1/8)c +7
= (5 7/8)c +7
This is 4x + 3 + 2x - 5
= 6x - 2 answer
