Answer:

p = $\frac{16}{3}$

Step-by-step explanation:

Given

$\frac{p}{20}$ = $\frac{p-4}{5}$ ( cross- multiply )

20(p - 4) = 5p ← distribute left side

20p - 80 = 5p ( subtract 5p from both sides )

15p - 80 = 0 ( add 80 to both sides )

15p = 80 ( divide both sides by 15 )

p = $\frac{80}{15}$ = $\frac{16}{3}$

Answer:

{10, 20, 30, 40, 50, 60}

Step-by-step explanation:

The function is:

$f(x)=10x\\\{x\in \mathbb{N}|1\leq x \leq 6\}$

State that the tange of function is the set of all output values of a function. Therefore, the answer cannot be {1, 2, 3, 4, 5, 6} and $1\leq x\leq 6$ . The answer is not $10\leq y\leq 60$ because its output will always be a natural number and it's not stated in the answer, like I did above. The answer is {10, 20, 30, 40, 50, 60}
