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
805043 would be the answer i believe
Answer:
The answer is 88.
Step-by-step explanation:
68+81+74+89+x/5=80
312+x/5=80
312+x=80*5
312+x=400
x=400-312
x=88
The amount of cloth needed to make 1 headband is 10 meters.
<h3>Unit value</h3>
- Number of headbands Anne made = 6
- Total clothes used = 3/5 meters
Cloth needed to make 1 headband = Number of headbands Anne made / Total clothes used
= 6 ÷ 3/5
= 6 × 5/3
= (6 × 5) / 3
= 30/3
= 10 meters
Therefore, the amount of cloth needed to make 1 headband is 10 meters.

Answer:
c is the answer. (Assuming that's a positive 5)
Step-by-step explanation:
You would use the slope formula: (y1 - y2)/(x1-x2).
Plugging in gives
(3--2)/(2-1)
(3+2)/(2-1)
which simplifies to:
5/1
= 5
