Step-by-step explanation:
This is a hard one but this may be correct
3 simple bracelets and 4 deluxe bracelets
0 simple bracelets and 6 deluxe bracelets
12 simple bracelets and 0 deluxe bracelets
7 simple bracelets and 3 deluxe bracelets
Given the inequality 9x + 20y > 120, it is easier to just substituting the answers from the choices and see which ones satisfy the inequality. From the choices, the correct answer is 7 simple bracelets and 3 deluxe bracelets, which yield an answer of 123, which is greater than 120.

Answer:
The approximate solution of the equation is 4,29.
Step-by-step explanation:
The solve of this fomula is:
5ˣ = 1000
You can use log in each side of the formula::
log₁₀ 5ˣ = log₁₀ 1000
By logarithm law (logₐ (mⁿ) = n logₐ m. And as log₁₀(1000) = 3:
x log₁₀ 5 = 3
x = 3 / log₁₀ 5
x ≈ 4,29
Thus, the approximate solution of the equation is 4,29.

Part 2 is 12.5 cm represents 5km
I worked this out by doing a ratio
5cm=2km
?cm=5km
you have to do 2 times 2.5 to get 5km so you do 5 times 2.5 to get 12.5cm
so the answer is that 12.5cm
