For this question you can say:
5/9( °F - 32) = -10 °C
so now you should solve the equation:
5F/9 - 160/9 = -10
⇒ 5F/9 = -10 + 160/9 ⇒ 5F/9 = -90/9 + 160/9 ⇒ 5F/9 = 70/9 ⇒ now you can multiply both sides of the equation by 9 so you will have:
5F = 70 ⇒ F = 14 ° F :)))
i hope this is helpful
have a nice day

Amber is starting a garden. She plants 2 flowers the first month. The next month, she plans three times more flowers (6 flowers)

Artist 52 [7]

This is a geometric progression problem. We can the general formula that can tell us how many flowers would be planted each month.
Let's write the terms that we know and see if we can find the pattern:
$
\begin{tabular}{lll}
Month & Number of flowers planted & Different form \\
1 & 2 & 2\cdot3^0 \\
2 & 6 & 2\cdot3^1 \\
3 & 18 & 2\cdot3^2 \\
4 & 54 & 2\cdot3^3
\end{tabular}
\end{table}$
The patern here is obvious. Let's write it down:
$N=2\cdot3^{n-1}$
This formula gives us a number of flowers planted in the n-th month.
