Answer:

H(x) = 5x - 10

H(x) + 10 = 5x

(H(x) + 10) ÷ 5 = x

Replace H(x) with x and x with H-1(x)

H-1(x) = (x + 10) ÷ 5

$\bf \cfrac{1}{\frac{5}{4}}=\cfrac{6}{x}\implies \cfrac{\frac{1}{1}}{\frac{5}{4}}=\cfrac{6}{x}\implies \cfrac{1}{1}\cdot \cfrac{4}{5}=\cfrac{6}{x}\implies \cfrac{4}{5}=\cfrac{6}{x}

Solve for n -19=-8+n

laila [671]

-------------------------------------------------------------------------------------------------------------

Answer: $\textsf{n = -11}$

-------------------------------------------------------------------------------------------------------------

Given: $\textsf{-19 = -8 + n}$

Find: $\textsf{Solve for n}$

Solution: In order to solve for n we need to add 8 to both sides which would cancel -8 on the right side and isolate n giving us the value of n.

Add 8 to both sides

$\textsf{-19 + 8 = -8 + 8 + n}$

$\textsf{-19 + 8 = n}$

$\textsf{-11 = n}$

Therefore, the final answer would be that n is equal to -11.

kherson [118]

Given:
land area of Alaska: 1,700,000 square kilometers
land area of Florida: 0.10 of Alaska

To find the land area of Florida, we multiply its decimal to the land area of Alaska

1,700,000 sq. km * 0.10 = 170,000 square kilometers.

The land area of Florida is 170,000 square kilometers. It is equal to 0.10 or 10% of the land area of Alaska.
