Answer:
B
Step-by-step explanation:
A differential equation is one that contains the derivative of a function. For example f(x) + 3 = 4f'(x) - 2. Usually you will be given one of the functions and initial conditions if you have to solve.

Tyrell worked on
16 - 2(4 + 3x)
what do brackets mean ? they mean that this operation has to be done before everything else in the expression.
as this contains a variable, we cannot fully calculate it, true, but we need to keep this in mind and always treat the content of the brackets as one package.
so, whatever I do from the outside with one part of that package, I have to do also with all the other parts of that package.
so, the multiplication with -2 has to happen with both : 4 and 3x. not just with 4.
therefore, the correct simplification looks like
16 - 8 - 6x
8 - 6x or -6x + 8
Amelia multiplied correctly, but then made a mistake summing things up
10x - 3(4x + 1)
10x - 12x - 3
10x - 12x = -2x
I can't mix the pure constant -3 into the factors of x. that would be like the famous mixing of apples and oranges.
so, the result is
-2x - 3
The recipe makes 8 pancakes.
He wants to make 12 pancakes.
First, find out how many times what he needs is compared to the recipe.
He wants 12 pancakes; the recipe makes 8 pancakes.
12/8 = 1.5
He wants to make 1.5 times the recipe.
Now multiply every ingredient amount by 1.5 to find what he needs to make 12 pancakes.
240 g of plain flour.
240 g * 1.5 = 360 g of plain flour
2 egs
2 eggs * 1.5 = 3 eggs
600 ml milk
600 ml * 1.5 = 900 ml
Answer: 360; 3; 900
