14x - 3
6x + 3
14x + 3
6x - 3
Answer:
6x - 3.
Step-by-step explanation:
4x + 3(2x -1) - 4x
= 4x + 6x - 3 - 4x
= 6x - 3.
The correct equivalent expression for 4x + 3(2x -1) - 4x is 6x - 3. This result is achieved by distributing, combining like terms, and simplifying.
The subject of this question is Mathematics, with the problem concerning simplifying expressions in algebra. To handle this problem, first expand the expression 4x + 3(2x -1) - 4x.
From this initial question, follow these steps:
The correct choice from the given list is therefore 6x - 3, which implies that the equivalent expression for 4x + 3(2x -1) - 4x is 6x - 3.

2 teaspoons
21+21=42 so for every 1 teaspoon there is 42 people
42+42=84 so it’s 2 teaspoons
Answer:
Let's imagine that x is the number of teaspoon of salt needed to make at least 84 cupcakes.
So we know that, 1 batch makes 21 cupcakes, and we need at least 84 cupcakes, so the number of cupcakes batch needed here should be:
84 ÷ 21 = 4 (batches)
Since we knew the number of batches that we need to make the cupcakes, we now calculate the amount of sugar needed. We have:
1/2 teaspoon of salt for every 1 batch.
x teaspoon of salt for every 4 batches.
x = (4 . 1/2) . 1 = 2 (teaspoons)
