15. marteen wants to paint 2/3 of her room today. she wants to paint 1/4
of that before lunch. how much of her room will she paint
today before lunch?

1/6

Step-by-step explanation:

2/3 x 1/4 is 2/12, which simplified is 1/6.

Marteen will paint 1/6 of her room today.

Step-by-step explanation:

In order to solve this equation, all you have to do is multiply how much of her room Marteen wants to paint today (2/3) by how much of that amount she wants to paint before lunch (1/4). because she wants to paint 1/4 of 2/3 of her room before lunch, you have to multiply 2/3 and 1/4. SO...

Multiply: 1/4 x 2/3 = 2/12

Simplify: 2/12 = 1/6

1/6

Hope this helps!

here is your mark brainliest

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
