For this case we must solve the following equation:

For this, we follow the steps below:
We find the Neperian logarithm on both sides of the equation to remove the variable from the exponent

We use one of the logarithm properties to extract x from the exponent:

We subtract xln (7) on both sides of the equation:

We take x common factor:

We divide between
on both sides of the equation, then:

Answer:

Answer:
Step-by-step explanation:
Each parrot gets 2 grapes in one day
In total: Lena gives her parrots(ALL FIVE OF THEM) 10 grapes all together
Okay so every part of sugar requires 4 parts of water
so
3434 cups of sugar x 4 (parts of water per 1 part of sugar) = 13736
She will need to use 13, 736 parts of water for 3, 434 parts of sugar
