<span>One side of a triangle is half the longest side. The third side is 8 m less than the longest side
Let x,x/2 and (x-8m) represent these sides
</span>

x + x/2 + (x-8m) = 42m
Solving for x
5/2x = 50m
x = 20m, the longest side. The other two are 10m and 12m
Three sides are: 10m,12m and 20m

F/13 = 6.2 what is the value of f
nekit [7.7K]

Answer:

The value of f is 80.6.

Step-by-step explanation:

We are given the equation and asked to solve for f.

If we are given a fraction with a variable in the numerator, we can multiply both sides of the equation by the denominator to isolate it.

For example, if you look at this equation:

\displaystyle\frac{a}{26}=17.9

We can multiply both sides by 26 to get the a by itself so the equation can be solved.

\displaystyle26\times\frac{a}{26}=17.9\times26\\\\a = 465.4

Therefore, we can apply this same technique to the equation \frac{f}{13}=6.2.

\displaystyle\frac{f}{13}=6.2\\\\13\times\frac{f}{13}=6.2\times13\\\\f = 80.6\ \text{or} \ \frac{403}{5}

Therefore, the value of f is 80.6.

Answer:

Nonproportional

Step-by-step explanation:

A line that is proportional will always pass through the origin (0, 0). If it does pass through the origin, then x and y have a proportional relationship.

Best of Luck!
